BREACHER'S CUSTOM GUNS AP5SD-K SBR - 9MM SD SHORT BARREL RIFLE, PORTED BARREL, 8" INTEGRAL SUPPRESSOR
The Breacher's Custom Guns AP5SD-K SBR is a true SD short barrel rifle built from a Century Arms MKE AP5SD and professionally converted by Breacher's Custom Guns with a ported barrel and an integrated 8" suppressor. The 5" SD barrel and K-length silencer work together the way the MP5SD was engineered to, bleeding 115gr standard-pressure 9mm ball ammunition down to subsonic velocities without any specialty ammo.
Under the conversion is the MKE's roller-delayed blowback action, which pairs with the integral suppressor for a shooting experience that's as smooth as it is quiet. This version also includes an optic rail, a hard case, and two 30-round magazines.
CAPITOL ARMORY'S OPINION
The MP5SD is one of the most iconic firearms ever made, but a quality, true SD conversion is hard to come by. Most of what's out there is cosmetic, either a fake shroud threaded onto the barrel or a normal silencer tucked inside the handguard. This one is the real deal, with a ported barrel doing the same work that made the original platform legendary.
Because the barrel drops standard ball ammo below the speed of sound before it leaves the muzzle, you don't have to go hunting for subsonic loads. Add the roller-delayed action's naturally soft, smooth cycling, and the AP5SD-K ends up being something special. If you've always wanted a proper SD-platform gun without tracking down a transferable or building one yourself, this is the one we'd point you to.
