This Wise Arms WA-15B is an AR-pattern pistol built around a 7.5-inch barrel in .300 Blackout, fitted with an SB Tactical SBA3 brace and finished in OD Green. The pairing is deliberate — .300 BLK was engineered specifically to perform from very short barrels, burning its powder completely in a few inches where 5.56 would be throwing unburned powder and muzzle blast. In a 7.5-inch gun, the difference is dramatic.

The result is one of the most compact serious defensive packages available, and it feeds from standard AR-15 magazines using AR controls you already know. It's also an outstanding suppressor host, since subsonic .300 BLK through a can from a short barrel is about as quiet as centerfire gets.
