Trigger Pull: The trigger pull on the Crosman DPMS SBR BB Rifle is single action only since the charging handle must be cocked first before you can shoot it. The trigger is short and fairly light but not too light that a misfire can happen easily. This M4 rifle makes for a great action shooter in semi-auto or full-auto mode!

Accuracy: My first volley was with 10 rounds in semi-auto firing mode and resulted in a tight grouping with 8 out of 10 shots landing within ¾-inches. I then adjusted the sector switch to the much more fun full-auto mode for the 15 remaining rounds and let her rip until the bolt locked back. To be honest I was fairly surprised at how tight the group was. It only spread out to about 2 inches with not too much vertical drop, so velocity remained pretty consistent.

Build Quality: The Crosman DPMS SBR is well made all around. Weighing in at 6.2 pounds, it feels sturdy and solid. There is a lot of metal both inside and out, but keep in mind the top and bottom receiver are polymer. Pretty much all the movie parts are metal, including the magazine, the internals, the buffer tube and the barrel.

Realism: The Crosman DPMS SBR is about as real as you are going to get in a blowback M4 style airgun. You can even take it apart into the top and bottom receivers like the real steal version. The blowback action gives you some recoil but more importantly offers a true single action trigger and of course the full auto ability we all love. Almost all the moving parts work like they would on a real M4, other than the forward assist which is molded into the receiver.

Pros:

• Most realistic M4/AR BB rifle on the market
• Full blowback operation with both semi and full auto shooting
• Fires up to 430 FPS, over 1400 rounds per minute
• Quadrail handguard provides room for laser and light accessories
• Equipped with angled forgrip
• Adjustable six position butt stock

Cons:

• Receiver is a polymer construction
• Magazine has a limited 25rd capacity
• Rear buttstock is not compatible with the AR platform

Comments: There's nothing not to love about the Crosman DPMS BB Rifle! The compact SBR (short barrel rifle) setup is lightweight and agile, perfect for target practice in full-auto mode. It's easy to upgrade with your choice of RIS accessories, and comes with some pre-installed features like flip-up iron sights and an angled forward grip. With an authentic single action trigger, functioning charging handle, and powerful blowback system, this gun provides an ultra-realistic M4 rifle firing experience!
