The 300SD is the premier integrally suppressed rifle built on the AR15 platform.
Chambered in 300 AAC Blackout, our unique maintenance free suppressor design allows a shorter overall length rifle that achieves superior suppression performance than a longer barrel rifle with the typical screw on suppressor.
The Integral Arms matching upper and lower receivers are machined from forged 7075 Aluminum and except all mil-spec components and accessories.
We use 1:7 and 1:8 twist barrels to stabilize the heavy 220 grain subsonic projectiles.
The 300SD can accept both subsonic ammo for extreme suppression as well as supersonic loads for longer range shooting.
The integral suppressor is built with a Titanium suppressor tube and 316 Stainless Steel baffles, for durability and many years of reliable service.
The 18″ suppressed upper is a sealed unit requiring only a single ATF tax stamp.
All NFA Rules Apply.
