Definitive Guide to Crosman DPMS SBR

The Crosman DPMS SBR (Short Barreled Rifle) is an accurate CO2 replica of an AR-15/M4 platform that fires 25 BBs in either semi or full automatic mode at 1400 rounds per minute and can be stripped down just like a typical AR. Crosman started with a DPMS PDW (Personal Defense Weapon) and added other tactical features like an angled foregrip, BUIS (Backup Iron Sights), and a mock suppressor while preserving the fully functioning controls and features of a real AR. If you are looking for an accurate replica of an AR-15 for training purposes or just plain full-auto fun then the Crosman DPMS SBR is the airgun for you! To learn more continue reading below.
Detailed Review
Crosman has partnered with Panther Arms to answer the call for an accurate replica of an AR-15 with full auto capability and fully functioning controls. With the Crosman DPMS SBR you are as close as you can get to the feel of the real firearm. It has full blowback and you will feel it!

The DPMS SBR weighs in at 6.5 lbs and measures 26.5" with the stock collapsed and 30.5" with the stock fully extended. Most of the DPMS's body is a high-quality polymer which feels and looks great.

Starting at the muzzle, there is a mock suppressor that screws off counter-clockwise to expose 14mm negative CCW standard airsoft threads which can be used for attaching aftermarket accessories. The DPMS comes with a Magpul-style angled foregrip and you can mount any accessories you like on the tactical quad rail, such as bipods, vertical grips, flashlights, and lasers.

The DPMS comes standard with BUIS (backup iron sights). They aren't spring loaded so you will need to push them all the way up and down firmly, but they work well and will co-witness with most red dot and laser sights. The front sight is non-adjustable and the dual aperture rear sight is adjustable for windage only and has a peep sight for precision shooting and an O2 (0-200 yard) sight for faster target acquisition. Of course, the BB version isn't going to shoot out to 200 yards but the sights are a pretty accurate representation of what you find on the firearm.

For a few more shekels you can get the DPMS kit, which includes a CenterPoint 1x30mm Large Battle Enclosed Reflex Sight with 3 MOA Red Dot and Picatinny mounts.

One thing that all replica aficionados will appreciate is the lack of white warning lettering all over the side. The warnings and licensing information are stamped subtly and don't detract from the authentic look and feel of the gun.

The grip is on the small side, although not unusually small for a tactical arm and can be replaced with any standard AR grip. Be aware that there are a couple of small springs you'll want to keep track of when you switch grips.

The DPMS SBR will fit any shooter due to the six position adjustable buttstock. Push the lever in and extend or collapse the buttstock, and push the lever in fully to remove the buttstock completely. The buffer tube functions as the hammer so you can't switch in other AR stocks.

The magazine holds the BBs, CO2, an Allen wrench for piercing the CO2, and also contains the valving for the gun. When you push the mag release button the magazine doesn't drop free but this is a good thing as it helps prevent falls and damage. The BBs double stack but not quite as much as some magazines so they feed reliably. We haven't had any problems with them, but one customer has reported that Dust Devils may occasionally hang up, but a little bit of Pellgunoil in the feed channel should fix that.

While the manual indicates that the follower locks in place for loading, that is not the case and it needs to be held back with a thumbnail, which is a bit of a pain. Good news is that Crosman includes a speed loader that makes loading the magazine a cinch. There is one caveat however, and that is if you don't use the BBs it likes it will jam up. We tested a number of BBs and Daisy and Marksman BBs jammed constantly, Crosman Copperheads jammed occasionally but worked overall, but the ones that worked flawlessly were Hornady Black Diamonds, Umarex Steel BBs, H&N Smart Shot, and Air Venturi Dust Devils. If the speed loader is jamming, don't force it. Shake it around, turn it upside down and tap it and try again. That will fix most issues, but you can avoid problems by staying away from larger BBs like the Daisy's.

To load the CO2, pop the front cover off lifting it up where it says OPEN. Insert the first co2 cartridge on the left and use the included Allen wrench to pierce it. You can stop here and only use one CO2 cartridge if you aren't going to be shooting much, otherwise insert the second cartridge on the right and pierce it also. Note that they must be done in this order or the cartridge on the right will release all the CO2 immediately. To minimize CO2 loss, snug up the piercing bolt and then give it a quick twist to puncture and seal completely.

Now, replace the cover, insert the magazine and slap it to seat it securely. Pull back the charging handle, which will open up the dust cover, select either semi or fully-automatic and you are ready to go! When you refill the BBs and seat the mag again you don't need to pull the charging handle, just push in the bolt release. A huge part of the fun of the DPMS SBR is how all of these controls work just like they should! In fact, the only thing that doesn't work is the forward assist and it wouldn't do anything in any case.

Everyone has asked for accurate AR15 field strip capability and the DPMS doesn't disappoint. Breaking it down is very easy. First remove the magazine and uncock the gun (pull the trigger). Now, push in the rear pin located up and back of the safety until you can pull it out from the other side. You should be able to do this with just your fingers, but a screwdriver or other tool may make it easier. Now the gun will open up and allow you to access the bolt assembly which can be completely removed by pulling out the charging handle. To completely remove the upper receiver from the lower remove the forward pin in the same fashion. Note that the forward pin is removable while the rear pin is captive.

If you have put around 3000 rounds through the DPMS SBR then this is a good time to do a little maintenance. With the bolt assembly removed or at least pulled back put a little silicone chamber oil on the green seal on the face of the bolt and also in the bolt housing the seal goes into.

The gun is not designed to be torn down further but if you get a BB jammed in the barrel and can't remove the magazine to push it out you may need to remove the barrel. This is a very unlikely scenario, in fact it should never happen unless you use Marksman BBs which are notorious for jamming CO2 airguns. First though, you should contact Crosman to have it serviced because disassembly of your DPMS may void the warranty. If that isn't an option for some reason, remove the two rear bolts on either side of the quad rail and the small screw in the middle of the optics rail. Wiggle the barrel assembly off and push the jammed BB out with a dowel or cleaning rod.

Performance and Accuracy
With CO2 replicas most people are looking for the fun factor more than pure accuracy but it is nice when they come together as they do with the Crosman DPMS SBR. We tested a few different BBs at ten yards: the least accurate were the Dust Devils, Crosman Copperheads were pretty accurate and the most accurate were the Hornady Black Diamond (this is no surprise as they are often the most accurate BBs in our testing) and the Excite Smart Shot BBs. We shot at ten yards with the peep sights and with the Crosman Red Dot and we confess to having a hard time with these particular peeps. The best we could do with the Black Diamonds was put 21 out of 25 into 1.75" with the full 25 shots taking up three inches of the target. With the red dot, 23 out of 25 went into 1.45" center-to-center and the full group measured 1.81". The Smart Shot lead BBs put 22 out of 25 in 1.4" with a few fliers (probably due to the trigger) opening it up to over 2.5". These are pretty good numbers for 25 shot groups from a BB gun! On full auto the groups opened up a lot, as is to be expected.

You can expect to get around 175 shots per fill if you are shooting semi-auto and about 150 if you are shooting full auto, although you will experience a noticeable slowing of the blowback for the last fifteen to twenty shots on either mode. This is pretty darn good, considering the amount of blowback this gun produces.

On semi-auto it isn't a particularly loud gun, metering in at 88.5 dB, and should be backyard friendly for most shooters. On full-auto the volume jumps up to 99.6 dB but it should still be fine for most backyards.

The trigger pull isn't light—on our Lyman trigger gauge it averaged 10 lbs 7 oz, which is heavier than the typical AR/M4 triggers, which tend to run from 5.5-8.5 lbs. However, for a gun like this that is meant for fun and not benchrest shooting the trigger, in our opinion, is just fine.

If you order our combo you will have most of what you need apart from CO2 and you will want to stock up on it! We recommend the Crosman 40 packs - they are the cheapest way to buy it and a box will last you quite a while.

If you don't buy our combo, then make sure you have some Pellgun oil to keep the seals and valve in good repair. One tube will last you a long time.

A good pair of safety glasses is always a must when you are shooting BBs, both for the shooter and any bystanders, and while ricochets are minimized with both the Smart Shot and Dust Devil BBs we still recommend you wear them anytime you have the Crosman DPMS out.
Accurate Tactical Replica When talking about tactical rifles it almost impossible to not mention the AR platform and now you can add "airgun" into the same conversation. Crosman brings us an accurate replica of the AR-15 with plenty of tactical rails, breakdown capabilities and semi/full-auto firing modes. Plus, it has blowback! When you hold the Crosman DPMS, it just feels good. Then when you fire it, well let's just say you'll have a big goofy grin on your face. Don't say we didn't warn you.

Performance First off, it's important to remember that this gun wasn't built for dime-sized groupings at 100 yards, but it is pretty accurate. We were impressed with an airgun that you can hold down the trigger on full-auto knocking down a group of cans and then switch to semi-auto to carefully pick off any stragglers. Add a tactical red-dot and laser and your accuracy will improve even further!

Not as Espected
Well built, ease of use - lifelike full detailed components. fun for ages 12 - 18
ProsWell built, ease of use - lifelike full detailed components Mags carry & have Hex Head Keys for tightening down Co2 Very nice feature.
Cons1. Magazines don't lock back to load as stated in the instructions. 2. 25 rounds on full auto is a joke & pathetically slow FPS. 3. Barely breaking a reactive paper target at 15 yards. 4. Better get several extra mags also. 5. Eats Co2 like candy 6. Comes with an additional cheesy forwarding handle grip no instructions on how or where it goes.
Best Uses1. Close range plinking fun for ages 12 - 18. 2. Authentic Sound & Motion effects.

Quality built, almost like the real thing!
I just received it and installed the co2 bb's and dot sight. First shot and subsequent firings jammed two BB's into the barrel. I was using the .177 BB's air gun depot sells, the Marksman BB Speed Loader with a package of BB's, model #1510. They are too big! DON"T USE THESE! Luckily the gun is pretty easy to disassemble and I got the barrel out and used a coat hanger to remove the two BBs. I then used some BB's I had for an old Daisy I have and checked that they would roll down the front of the barrel to the action, and they did, so sighted it in in semi and went full auto! Too awesome!!!
ProsDis-assembles like the real thing, easy to figure out even without reading instructions. Nice clip that holds two co2's and 25 BBs. Seems very accurate in semi, and very nice in auto.
ConsNeed a better auto loader. Mine will not work, jams unless I put in only a few BBs.
Best UsesBest used for fun.

Happy With This Gun
I have both BB and pellet guns. This DPMS is one of my favorite shooters. It is very accurate for a BB gun and the rapid automatic fire is amazing. I have no regrets about this purchase. The staff at Airgun Depot are responsive and the order arrived in good time.

Crosman DPMS SBR
Hey you reviewers. When received my Crosman DPMS SBR I was excited to open the box and see this gun. I liked the way it looked and the way it felt. It felt like the real thing it shots great. I'm pretty happy with it but there is somethings that could have been changed or added to this air gun.
ProsThe good things about this air gun is that it looks real and it shoots very good in semi and in fullauto. The rails all the way around for additional hardware and the charging handle felt real when pulling back. The adjustable stock was great and the forearm grip with the speed loader was a nice addition.
ConsThe things that I thought that could have been better was basically on the magazine because it didn't hold enough bb's and if it wasn't for the speed loader it would have made it difficult to load the bb's into the magazine. The pop up sight's should have been doing loaded
Best UsesI like the way it shoots and feels. I having lots of fun with it.

fun to shoot but failed after 100 bb's
Fun but it stopped working. The bolt would not seat fully forward. I think it's the magazine. Everything else in the receiver looks fine. Very disappointed. Another website is offering extra magazines so I just pre-ordered 2. $50.00 each. The other website is named after one of the 3 famous structures in Egypt. If this isn't the problem I will ask for a replacement.
Consstopped working.

lots of fun and very safe
Although a gun owner since leaving the Navy in 1978 , I never had a BB gun before this. It caught my eye and decided , at $180, what the heck. First thing , replaced muzzle brake with an old AK bird cage brake I had lying around and it fit perfectly. Shot about 100 rounds - hated the crappy plastic folding sites and replaced them with some old flip up iron sites that were lying around. Then really tacked it out with a old cheap micro red dot and a laser /flashlight combo on the top rail . Took it to my sons house and we set up some targets in back yard and before long some of his friends (Gulf War Vets ) came over and we had a great time

OMG! This thing is awesome. very fast rate of fire, ammo cheap actual weight is about the same as my real AR-15s great training aid everything works just like my real rifles cheaper to shoot get lots of muscle memory in without spending a fortune on 5.56 ammo.

Best purchase I've made in a long time.
This bb gun is soooo awesome! As a former SWAT cop used to shooting the real thing, this a close second. Perfect for backyard fun.

More fun than the real thing!
This thing is a blast and my son and I went through a box of co2 and a bottle of BBs in the first weekend. I strapped a flashlight and a 4x scope off my old truck rifle and it's perfect to get rid of those pesky squires and possums that harass our dogs. Also great to teach youngsters some gun safety for when they want to shoot the real thing. DPMS did a great job making this an accurate and fun B.B. rifle.
ProsFun, accurate for a smooth bore and full auto is almost as much fun as the real thing!
Cons25 shots goes fast, would love extra mags
Best UsesTarget practice, pest deterrent, gun safety training
July 29, 2018
Extremely realistic!
Got this after months of waiting, and I am very happy with it. Shooting is realistic and I love that the BBs and CO2 are in the magazine together for realistic reloading. Only issue I have is you need at least 2 magazines to practice magazine changes and so far I can't find an extra available for order.
ProsRealistic blowback action and good accuracy.
ConsShould hold 30 rounds like a standard AR-15 magazine, and would be great if offered with an extra magazine.
Best UsesGreat for cheap and convenient training, and for teaching gun safety to kids.

very disappointed
watched the evaluation in youtube this weekend and started firing in semi-auto but only shot 5 bbs when it quit working altogether. checked for jam, replaced bbs in magazine and even replaced the co2 cartriges but to no avail. Charging handle works but for some reason bolt will not move forward all the way. even tried pulling trigger without the magazine but no co2 is being released. am returning item this week.
Proslooks like the real thing
Conswas wondering if this is one of the issue(s) that caused delay in releasing this product

it's great, but......
This air rifle is, in my opinion, fantastic. It realism, is unmatched thus far, in a steel bb are platform. Even the hellboy isent as realistic. I'm giving it 5 stars so far. But, it needs more magazines. The speed loader is great, but it should come with at least, 2 mags. It's a must!! I'm going crazy, waiting for crossman to release extras, so I can do some mag changes. But other than that, awesome.
ProsAwesome replica
ConsRuns out of bbs fast. Needs more mags!!!!!!!

Beautiful replica, questionable operation
I received mine this morning excitedly after a 6 month wait. Nice packaging, similar to Umarex. Includes a speed loader (Umarex should have done this with the MP40, so bonus points for Crosman).Weight and feel are second to none. You could easily mistake this for a real Panther Arms AR-15. Solid, beautiful design. You can remove the backup iron sights and foregrip if you want (or adjust them). Biggest surprise yet- I pushed the receiver pins to see if they were real or not. The rear pin slid out and stayed in played. With quick yank and much to my surprise the upper and lower receiver disassemble just like the real gun. The internals look different, but there is an auto sear! As for shooting, it's a BB gun. Blowback is very solid. Trigger pull is heavy, but it's fine. Full auto is awesome. The bolt stays back on the last round.
ProsLooks great, feels great, shoots great. Equal to the Umarex MP 40 as my favorite replica. If you've ever wanted an M4 that is FULLY functional, look no further.
ConsReceivers and dust cover are not aluminum (Although the glass filled Nylon is very durable and you won't notice). Forward assist is non-functional (err... who cares, it's not going to jam). Weird flash hider is not removable.
Best UsesPlinking, teaching gun safety, showing off.
