Key Features
- 10.5-inch Chrome Moly Barrel — Why it matters: Shorter barrel keeps the gun maneuverable in tight spaces like barns, trucks, or brush, while the chrome moly steel holds up to hard use and rapid fire without warping.
- F-Marked Front Sight Base — Why it matters: This gas block is machined to the correct height for a standard AR-15 front sight, giving you a reliable iron sight setup that won’t shift under recoil or when banged against a fence post.
- Full-Auto Profile Bolt Carrier Group — Why it matters: The heavier carrier adds mass to slow the cyclic rate and improve reliability with various ammunition, plus it’s phosphate-coated for corrosion resistance in wet or dusty conditions.
- DPMS CAR-Style Blade Brace — Why it matters: This brace keeps the pistol legal while giving you a stable platform to shoulder or brace against your forearm, making it easier to control follow-up shots from the cab of a truck or on uneven ground.
- M4 Handguard with Heat Shields — Why it matters: The heat shields protect your support hand during extended strings of fire, and the classic M4 profile lets you mount a vertical grip or light without needing a free-float rail.
Who It’s For
This pistol is built for ranchers, rural workers, and anyone who needs a compact AR that can handle varmint control, property defense, or truck gun duty. If you’re working fence line, checking cattle, or dealing with coyotes in tight cover, the 10.5-inch barrel and blade brace give you a package that stows easily and points fast.
Pros & Cons
- Pros: Compact and easy to maneuver in tight spaces; reliable mil-spec parts make repairs simple; blade brace keeps it legal as a pistol; chrome moly barrel is durable and accurate enough for ranch work.
- Cons: The 10.5-inch barrel produces a significant muzzle blast and flash, especially with the A2 flash hider — you’ll want ear pro even more than usual. The blade brace is not as comfortable as a padded pistol brace, but it gets the job done.

FAQ
Is the DPMS DP51655159026 legal to own as a pistol?
Yes, it is sold as a pistol with a blade brace and has a barrel under 16 inches. Check your state and local laws regarding pistol braces and overall length — most states allow it with a valid pistol permit or constitutional carry.
Can I mount a red dot or scope on this pistol?
The upper receiver is flat-top, so you can mount any standard Picatinny optic. The detachable carry handle gives you iron sights out of the box, but you can remove it and add a red dot or low-power scope for faster target acquisition.
What kind of accuracy can I expect from the 10.5-inch barrel?
With quality 5.56 ammunition, expect 2-3 MOA at 100 yards — plenty for coyotes, hogs, or steel plates. The shorter barrel loses some velocity compared to a 16-inch, but it’s still effective inside 300 yards for ranch use.
Does the blade brace work well for one-handed shooting?
The blade is designed to be strapped to your forearm for one-handed use, but it also works as a cheek weld when shouldered. It’s not as comfortable as a padded SBA3, but it’s functional and keeps the gun legal.
