The 8.5" 4150 CMV steel barrel balances maneuverability with ballistic efficiency, making the most of .300 BLK’s capability—especially when running subsonic ammunition or a suppressor.
PSA’s forged multi-cal lower offers broad parts commonality and straightforward upper swaps, giving the buyer flexibility to change calibers or configurations down the road without extra paperwork.
A lightweight 7" free-float M-LOK rail keeps the front end slim while providing ample real estate for lights, lasers, or hand stops. The rail’s free-float design also helps maintain accuracy by eliminating pressure on the barrel.
The ambidextrous extended charging handle improves manipulation from either shoulder, and the manual safety and standard magazine release keep controls familiar for any AR user.
A KAK Shockwave Blade brace adds stability without excessive weight and adjusts for length to suit different shooters or transport needs.
