The Build Story
Carbine capability in a packable footprint
The 11.5” barrel is the sweet spot for an AR pistol: short enough to live in a pack, a truck, or a bag, long enough to keep 5.56 doing real work. Braced and balanced, it drives like a carbine but stows like a handgun, the platform you keep close when a full-length rifle isn’t practical. Available in pistol or SBR configuration, set to your legal setup at order.
The RMR earns its reputation
We top this build with the Trijicon RMR Type 2 because nothing has out-survived it. On a 1.93” mount it sits at a natural carbine height, co-witnessed and zeroed, with a forward-mounted Mini Scout light to keep the package tight. Optic, light, and brace are installed and proven as one system before it ships.
Hand-built around how you’ll carry it
Every AR pistol leaves our bench torqued, staked, and function-checked through a live-fire shakedown. We set it up for fast presentation from a bag or a vehicle, because the gun you can actually deploy is the one that matters. Engineered and proven, no bare-bones compromises.
