Looks and feels like an M4 firearm. Shoots either BBs or pellets, so you can use whatever ammo you've got on hand. Since it's a multi-pump, you can pump it up to 10 times to get higher velocities or less if you'd like to do some easy all-day shooting. Get extra clips (same ones used by the Crosman 760 Pumpmaster) and load up so you don't have to interrupt your range time with a lot of reloading. A neat kit that gets you shooting the minute the box arrives! Includes everything for family shooting fun, indoors or out.

  • 18-rd BB mag, 5-rd pellet mag
  • 350 Round BB Reservoir
  • Rear Sight Adjustable for Windage
  • Post Front Sight Adjustable for Elevation
  • Both Sights are Removable
  • Weaver/Picatinny optics rails above the receiver, below the front sight fitting and on the underside of the forearm
  • Adjustable/telescoping stock (30.5" to 33.75")
  • Sling Loops
  • Manual Safety
  • Includes Sight Adjustment Tool, Targets, Pellets, Steel BBs and Safety Glasses

When you shoot steel BBs, do not shoot at hard objects or water. The BBs will ricochet! No matter what ammo you're using, remember to wear safety glasses. Everyone in the vicinity of the range should wear safety glasses, even if they're not shooting. Remember to remove all pets from the range before you start shooting.

Replaced my Pumpmaster with this rifle kit. Rifled barrel is much more accurate than the smooth bored Pumpmaster. Does it have a lot of plastic? Yes. My opinion, this is durable material, thick and textured. Example, I first thought the entire underside of the pump handle was a picatinny rail. Only front most portion is. I bought a separate flat bottomed rail, took down the raised ridges on bottom pump piece with a dremel tool, drilled through the bottom, added the rail with two 8-32 tapered head screws and locknuts, which are a perfect fit along the inside groove. No need for a wrench, nuts won’t turn inside groove. Tightened down rail securely. No cracking, chipping at all of plastic. This was all for adding a hand brake, which also turned out to be the perfect pump aid. Liked the authentic look of gun with the top hand rail. Sights take getting used to. Rear/handle sight is adjustable for both elevation and windage. My front sight was not adjustable for elevation, it was fixed and the kit didn’t come with any tool. Call to Crosman’s customer service went smoothly (they second to none), immediately an adjustable front sight and tool were in the mail. If your hands are big enough you can improve the velocity of this gun. There is no o ring or seal of any kind for the bolt probe so there’s a lot of air wasted on blowback. If you can keep your pointer finger on trigger and get your thumb up to the back of the bolt handle and keep it pushed forward while shooting I was getting 80 fps more than without pushing the bolt forward. Fun gun and you won’t find a better price than Airgun Depots.
ProsPrice, quality for price, accuracy
ConsUpwards of 10 pumps it can get difficult
Best UsesTargets, pests

Not so good.
January 29, 2019
I have had this for a couple months now and don't really use it. I can't hit anything with it. This is due to the fact that I can not adjust the sight since it didn't come with the sight adjustment tool. There are also very sharp edges and the handle for the pump. Been a little disappointed.
Best UsesSetting in a closet.

December 31, 2018
I bought the rifle for the appearance then I tricked it out Bi-Pod, Scope w/mount, flash light I have it stored in a tactical carry bag. The adjustable butt stock is great. From a distance you can’t tell if it’s authentic AR and it shoots well 20 to 30 yard accuracy is great. You can’t go wrong buying a Crosman Rifle or Pistol. Another fantastic buy is the 2100 edition, you can’t find a bad thing to say about that rifle either 15 or 20 years back they had a Anniversary edition of the 2100 series that came with a wood stock. Wish they would bring that back.
Thanks Crosman,

I have had one for +5 years now, shoots as fine when first unboxed.
I have fewer pests around my yard now so my frequent use is now limited to paper and metal foil pie plates. This BB/Pellet gun is VERY accurate when sighted in correctly. Love it and i am looking to buy another one shortly.

March 20, 2018
Im new to air guns so decided to purchase this Combo kit as a start and found this to be a good value. Fired fairly accurate right out of the box without any adjustments to the sights. 3-5 pumps was sufficient and with little effort. Had issues understanding directions on how to load pellets but that was because of being a novice and a beginner. Instructions says to load pellets nose first but which is side is the nose there is a flat side and open side. Emailed Air Gun Depot and they replied promptly answering my question. EXCELLENT RESPONSIVINESS!!!

Had fun shooting this M4-177 as a beginner and will try other air guns soon. Recommend to purchase additional magazines.

Crosman m4 tactical combo
October 26, 2017
This m4 tactical combo kit has been a nice surprise for all that you receive for the price. Alls there to start dialing in the sights immediately. I've owned a few crosman pellet rifles and pistols since I was a kid. This one is perfect for beginners who will enjoy target and can plinking. 4to5 pumps is all it takes to get sufficient power and accuracy. Comes with 3 clips which is good for 5 shots a clip. I purchased 8 extra crosman fire power clips, which enables me 55 shots without loading more clips for a while. Get some Pelligun oil also, eases pumping fatigue great bang for your buck
ProsGood accuracy for price looks like a real military ridle

For an air rifle in this price range I'm pretty impressed. Haven't actually bought very many lower dollar guns, but received an email from airgundepot for this item in combo & on sale. Could not resist since I like to collect. Good choice ; must be because it's a Crosman....
ProsFit & finish is excellent for the $$ spent. Everything fits tight ; even the adjustable buttstock fits snug. Pump action is very good & not sloppy. After 6 or 7 pumps it gets a little stiff, so I'd say 10 is plenty. Seems reasonably accurate so far. The mag fits nice & snug with room for a couple more clips in the storage. Sights mounted easily...Very nice replica & glad I bought it
ConsA bit light in weight for older adult folks but still a nice gun. Would be ideal for young individuals starting out in the world of gun ownership & learning good safety practices. The front sight pin appears molded in to the body of the sight so looks like it is not adjustable

May 24, 2017
I have not owned a "BB" gun since I was 12 but I had a war on with the rabbits and my garden was the battlefield. living in town fire arms are frowned upon so I had to opt for the silent approach. In the first 2 days after acquiring the M4-177 Tactical Combo the score stands at me3 - rabbits 0. Weapon works just fine!
Simple and fun design, sights just like the old M-16 that got me through several years in the Marine Corps and only took a few clips to lock it in. shoots a nice quarter size group at 50 feet.
ProsAccurate and easy to use, nice storage in the magazine for pellet clips.
Conswish the pellet clip design allowed a bolt home position that retains the clip without chambering.

December 10, 2016
Everything you said about the weapon was true. the 700fps right on, the adjustable stock, the ability to hold 300+ bb's and the 5 pellets x 3 (two additional pellet holders) give you plenty of shooting time. . I recommend pumping it up 5 times to achieve maximum power if you are going after rodents and pests and if you are a "good" shot, raccoons etc aim for the upper neck or throat for a deadlyt shot.
The heft to the rifle is perfect but make no mistake about it, IT IS NOT A TOY, so treat it as a real dangerous weapon.

ProsReal feel and adjustable sites for accuracy. The price as well is quite reasonable.

Accurate, but not sturdy
November 28, 2015
I opened up the box, removed the rifle gave it a pump and broken! The upper piece of hand guard was cracked. No big deal, it was whare the front secures around barrel I planned on tapping around to quiet down pumping anyway.just not so far forward towards center. Set rifle down walked away, came back and picked it up by the flash suppressor and it broke off entirely. That's whare the front sight mounts also. Maybe it got banged around during shipping, but cheap plastic. So I mounted a 3-9X40 scope and got it zeroed at twenty yards. Five shot groups that cover a quarter with crosman hollow points. The 760 is much sturdier but no whare as accurate with pellets. I won't be shooting bb's through this. My son will be able to grow with this one cause of adjustable stock... If it doesn't break first. But overall happy with it.
ProsAdjustable for young/small shooters. Excellent accuracy for the price. Decent power. Five shot clips. Looks cool. Lots of rails. Did I say accurate?
ConsAfter six, pumps get difficult. Cheap plastic. Have to shim scope to zero. Akward pumping especially with scope but also without.

Crosman Fun Gun M4-177 Multipump Air Rifle
November 24, 2014
The first thing I did was remove the carry handle and sights, then I installed
a 3x9x40 scope.

Next I went through my AR parts drawer...Flashlight, Red Laser on a 45 degree
side mount. All of the fun stuff.
ProsIt looks good. Hard to tell it fro my real AR's. It will shoot nickle sized groups, with 5 pumps, at 45' with the (low cost) Crosman domed pellets. What more can you ask of an economy priced airgun?
ConsThe rail under the barrel is useless. Anything mounted there will interfere with the pump handle, but I didn't remove it as I believe it helps strengthen the assembly. Even with my short arms, I had to install 3/4" spacer on the end of the butt stock.

This rifle was a pleasant surprise. Shoots straight, works well with a red dot laser, easy to set the sights, easy to pump. The only thing was I wished it was offered with wood stocks. I bought a refurb laser to fit this rifle. The laser was not refurbed and did not work. 2 broken wires(repaired), and replace 3 dead batteries and it works. The refurb company should hire me.
ConsPlastic stocks.

March 27, 2014
When you take it out of the box, it doesn't take long to sight it in. When its sighted , and your a good shot, you get accurate shots in an area no larger than an inch. It really is rifled! The ammo clip is just an empty case. Doesn't come with ammo just to let you guys know. Good gun for the price.
Pros-Lightweight -Accurate -Durable -Blew a big hole through my plastic bin. (It was thick)
Cons-Your gonna want some more ammo clips.

August 21, 2013
This gun is a great pellet gun. I use it for plinking and shooting small birds. It definitely has the power for both my uses. When target shooting, I do not have any shot that fly off into nowhereville. They all stay In a nice group. However, the sights are not all that great past 25 yards. The front pin takes up too much of the field of view to be useful. Upgrade to an inexpensive red-dot sight and this problem will be fixed. The bottom rails are useless unless you mount a small item there. The pumping action.
ProsAccurate Decent power Light Very cool
ConsIncluded sights are sub-par The bottom rails are useless

June 18, 2013
To be honest, this gun is amazing!! It looks & feels like a real firearm! There is a lot of little details for this gun, first of all is the little mag, it ain't real, it ain't the place to pour the pellets in, but it could be useful for putting little things in it, but besides that this gun is pretty cool. Worth those 70 bucks, for me.
ConsNot much, only the stock sights :/

A fun little rifle
March 30, 2013
I bought this rifle at Walmart, about a month ago. After 24 yrs in the military, I wanted an M16 type rifle. The wife shot that down....chuckles. It shoots well but the sights that come with it are pretty much useless. Yesterday, I bought an inexpensive tactical reflex sight for it. It took about an hour to zero it in, but now it is right on at 30 yds.

My only complaint is that it should be Co2 powered, with a self loading magazine for the pellets. Having to pump it up to 10 times between each round gets old. For plinking, and nuisance bird hunting, (we have thousands of European Starlings around here that get into everything), it should excel.
ProsLooks great and shoot straight.
ConsPumping it between each round is a pain. Stock sights are useless

Crossman M4-177 Caliber Air Rifle
January 21, 2013
I am liking my pellet air rifle now that I finally got it zeroed-in! It took me forever to get the manual sights adjusted to the bulls eye but when I did I found the fifle is very accurate with each shot fired........finally. As an expert marksman with my S/A Kimber 45 handgun I am embarressed to put in print the mistake I was doing with the sight alignment of the pellet rifle, but all is well that ends well ! I got the rifle for target practice because ammo is too expensive to buy just for target practice for my .45cal Kimber and also a .357 magnum. Making the price of bullets to high for folks to buy is just another form of gun control......screwed again!

Got this for me and my 3 year old
January 15, 2013
I have had BB/pellet rifles and pistols my whole life. I got this gun at Walmart locally to have a second rifle to teach my 3 year old. My eldest son has a Crosman 66 powermaster pellet rifle. They shoot almost the same. I added the same scopes to both rifles (Gamo 22 special 4x32) and they both hit great with pellets. The 66 powermaster, is a better gun with BB's, but I didn't get it for BB's. I am teaching my wife and daughter to use the pellet rifles before buying them actual firearms.

The M4-177 is the right size for my 3 year old to adjust the but stock and reach the trigger. It also works with my 18 year old too. What more could you ask for!
ProsThe rails Adjustable stock Name brand Works good with pellets (love the Gamo Red Fire pellets in it).
ConsTrigger pull too long Not as easy to just drop in pellets, need to use small clip. Needs a longer clip for pellets. HATE the pistol grip! Sharp to use left handed, cut my had up after 1 hour shooting!

Amazing Rifle
December 7, 2012
I bought this Rifle cause I spent so much time with it during my military services. Honestly, I referred to it as a toy to play in the backyard. My expectations were very low, to be honest. Plastic air rifle that shoots BB's and pellets? Come on.
But I was wrong. It is still an air rifle, plastic and etc. don't get me wrong, but it shoots so accurate
I was amazed. Out of the box, I zeroed it with the blank paper with the cross in the middle, using pellets from free standing position on 30 feet distance. I made a couple of good shots and decided I want to test it on real target. So I bought official qualification air gun rifle 25 feet target and made 5 shots in 5 targets on it.
Well not bulls eyes all of them just 1 shot made to 10 but 3 shots in 9 and 1 made 8 from free standing position on 25 feet. Peep sights from the box BTW not red dot or etc. I honestly didn't expect that accuracy from this toy. Amazing. Don't get me wrong, it is still not competition rifle and not the firearm, but I don't call it toy anymore either.
I wish they would make a version with the spring and the self indexing clip like Baikal's IZH for example. Pumping and you want the same number of pumps which you used during the zeroing the rifle which is 10 for me kills. Hands getting tired and shake and that affects accuracy. I hope I would make all 10s otherwise ;)
ProsAccurate Not exact but close replica Price
ConsPumping vs spring Weight could be bigger Not self indexing clip Sights especially front are plastic (you can't even use the lighter to make it darker for night shooting). Used this Russian trick to make the front sight darker than the night for night shooting yet in IDF.

Okey, when I shoot with BB or pellet it shoots strong and makes a great impact. But the greatest disspointment was that its not and semi-automatic, but its not listed like that, but it would be amazing if it was! So now you need to fill the chamber with a pellet or BB. It's cool to that you don't need Co2. But if there was one with Co2, I would buy it again! Looks cool, its heavy and the Laser that you can buy in the shop is great with it.

Great backyard plinker!
January 19, 2012
I have to say I am impressed with the Crosman M4-177. I bought mine the first day they were available for sale (the earliest production run were branded "M417").
The M4-177 is based on the Crosman 760 multi-pump powerplant. This is a decades old, tried and tested platform. With proper care and use, the M4-177 should last for many years.
The M4-177 is a very close replica of the military M4 carbine, or civilian AR-15. Some of the dimensions are a little off, such as the pump handle/ heat shield forearm, which is a little beefier than the real steel version, but overall the Crosman offering is a good copy.
The majority of the Crosman M4 is made of a tough engineering polymer, the major exceptions being the internal rifled steel barrel, the steel compression tube, and most of the pump linkage parts. The polymer pump piston is the same as that found in the Crosman 760 and 66/664 series rifles.
This air rifle will accept either BB's -- gravity fed and magnetically loaded from an internal "ready track", in turn supplied by a bulk reservoir in the receiver -- or .177 caliber pellets -- fed via a 5-shot stick magazine, manually indexed. The M4 comes packaged with one pellet magazine, and a sight adjustment tool; both of these items can be stored in the faux "shorty" magazine inserted into the magazine well immediately forward of the trigger group.
Operationally, the M4-177 works just like other, lower-cost multi-pump rifles. Anyone familiar with the Crosman 760, 2100, 66 (664), or Remington Airmaster 77 will be completely at home putting the M4-177 into operation.
The sights are usable, but are rudimentary. Both the front and rear sight are removeable. The flat-top receiver has a molded-in Weaver-style rail for mounting optics -- I prefer to use a red-dot sight on this platform for plinking.
The forward portion of the barrel has two additional Weaver rail for mounting accessories. Unfortunately, opening the pumping arm interferes with the placement of the lower rail, eliminating all but the smallest accessories. The upper rail on the barrel is intended for the front sight, but with this removed, there is room for a flashlight or laser, etc... It would have been nice if Crosman had designed this bit to include the upper rail and two side rails, instead of the lower, unusable rail.
As designed, the Crosman M4-177 will accept most two-point slings, with primary attachment points at the rail adapter on the front of the barrel and at the rear of the collapsible buttstock.
The M4-177 is not a very powerful air rifle (remember, it is basically a Crosman 760 Pumpmaster in tactical clothing), but it generates more than enough muzzle energy for backyard plinking. Having a pnematic powerplant, there is no "recoil" - though the shooter will feel a very slight impulse from the movement of the striker weight - and the trigger is crisp. Accuracy, therefore, is quite decent, provided the shooter follows good practices.
It is NOT intended for hunting, or even for small pest control (shooting at, say, anything larger than a small bird, would be irresponsible).
ProsGood replica. Affordable. Multi-shot. Dependable build - both sturdiness of this construction, and the proven design upon which it is based (the 760). Good accuracy. Easy to use.
ConsSights are only so-so. Could be heavier. Manual indexing of magazine (providing automatic indexing would greatly increase the price, though...). Only offered in .177 (but again, tooling up to produce a .22 would add a lot of cost...)

i personally think that this rifle is on the cheap side but it looks cool. it really has no purpose being an air gun it should be an airsoft gun. its really pointless to make an air rifle like this for the looks

My experience with this rifle is awesome I have a 6 inch spread a 35 yards with pellets, and 2.5 inch spread at 32 yards
I had it for a while and it great when you get use to it.

A fair first pellet gun.

Good pellet gun. Lousy BB gun. Fires pellets consistantly at 20 feet away. Good luck trying to get it to fire BBs. If you do, I hope have fun loading the BBs.
The gun supports many attachments, optics, mounts, and other add-ons. Don't use a for grip. Supports a sling, but the sling must be fed through some of the holes on the gun (no swivels). The firing rate is very minimal. I recommend that this gun is not to be used as a BB gun.
ProsThe pellets fire relatively consistantly. Shot groups are within a one inch diameter when fired from a bipod at 20 feet away. The rail system alow for attaching scopes on top, a laser sight on the barrel, and a bipod on the pump. A AR-15/M-16 style handle can also be attached.
ConsI could not get the gun to fire BBs. The instructions call for the user to "shake" the gun after loading the BBs so that the BBs load into the chamber. This is not a very effective our user-friendly design for a BB gun. Firing the pellets remind me of firing a musket. You must pump the gun seven times. Pull the slide/bolt to the rear. Load the clip, or slide the clip to the next pellet position. Push the slide/forward. Aim and then squeze the trigger. Repeat these steps to fire the next round. The rail on the pump is too far forward and defeats the purpose of attaching a fore-grip for support. There are no sling swivels attached. The sling must be fed through minor openings on the stock and barrel to attach it. The magizine is for show and has no value added.

Fun Gun

It has been a great little bb, pellet gun. It is nice to have a large capacity reservoir for the bbs. Pellets are great at about 670 fps, with 10 pumps. Fairly accurate once you get the hang of it. I got 4" groups at 25 yds. with pellets and about 6 with bbs. Acceptable for what I do with it.
ProsEasy to pump and fairly accurate.
ConsPlastic, plastic, plastic

nice pump gun

Based on a proven crosman powerplant, it is a very nice pumper. I had a heart to heart with crosman when I got mine. It is fairly accurate but the sights are a bit cheesy. When you get yours the next thing you should do is toss the stock sights and either buy some real AR sights or install a dot sight. Also a laser under the barrel would be a nice touch.
ProsLooks like a real m4 relatively quiet, uses bbs and pellets. Doesn't require co2 so you can shoot all day with minimal cost. Except for one tiny screw the entire gun is american made.
ConsI'd love to see this rifle based on the 1077 platform too. Totally hate the fact that the thing is plastic from butt ti flash suppressor. It's a great gun but all that plastic just screams CHEAP!

Cool new pump air rifle
November 10, 2011
Decided to try out this new pump air rifle from Crosman. It's based on the reliable 760B powerplant and just looks cool. It can shoot bb's out of a reservoir or pellets from the same clips that the 760 uses. Overall great gun.
ProsWeaver rail makes it easy to mount accessories like lasers, flashlights etc. Shoots both bb's and pellets. Looks
Consnone so far.

The pump handle seems a bit flimsy, so does it pump nicely or does it feel like you're going to break it. I pump fast and hard so I don't want it to fold on me or something.
I assume pumping is loud too? I know my old 760 was as the handle hit the gun but I was able to dampen that with leather at the contact point. Should I expect similar here or have they improved the design, or?
Double checking with you, the barrel is rifled correct? It says rifled but it also says it's a 760 underneath which is not rifled...

Does this gun take co2 and is it hard to pump the gun?
By Staff on April 13, 2012

This gun does not use CO2.
As far as how hard it is to pump, it gets more difficult as you put more pump it up more times, but you should have no problem getting enough pumps in for good shots.
