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.

Ok, bought for my nephew.

Made of cheap plastic not as well made as other hard plastic higher priced Airgun but suitable as a gift for kids. Read manual as some of the functions is not something you just fiddle without knowing the gun. The dual pellet and BB ammo is a plus.

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.
It 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?
The 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.

Buy the MP4 Winchester...its fed by two co2 pumping...also will fire auto...metal upper receiver...more like the real deal. A little more money but worth it.
Low cost.
Too much pumping.

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.
Looks great and shoot straight.
Pumping it between each round is a pain. Stock sights are useless

Excellent and would recommend to anyone. Well built, even though mostly plastic. Very accurate and looks real. Never pumped more than 3 times to get bullseye at 40 feet.
The look and accuracy as well as price.

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...

I need something to kill squirrels in the city'. Will this do the job?
By Staff on March 5, 2012

This should do fine.

By austin from Templeton,Massachusetts on April 11, 2012
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.
