The PTR 91 51P PDWR .308 Win 8.5" MP5-style pistol delivers modern rifle caliber firepower in a compact, maneuverable platform. Built on the proven delayed blowback roller-lock system, this short-barreled powerhouse chambers .308 Winchester and feeds from 20-round magazines, making it a serious option for shooters who want precision rifle performance in a pistol-length package. Whether you're setting up a truck gun, a home-defense rifle, or a specialized range rig, the 51P PDWR cuts through the noise with genuine engineering—not compromise.
The 8.125-inch match-grade bull barrel is threaded 5/8x24, ready for suppressors or the included H&K Navy-type flash hider. The MP5-inspired ergonomics include a wide polymer handguard and polymer trigger group that should feel familiar if you've run modern tactical rifles. At 7.8 pounds and 23.5 inches overall, it's built to move with you, not against you. The machined butt cap is drilled and tapped for an AR15 tube-style stock adapter, giving you flexibility to configure the platform to your needs. You get a paddle magazine release for speed, welded picatinny rail for optics, and sling swivel for field carry.
This is a rifle-caliber pistol for shooters who understand what that means—it's not a carbine with the stock removed, it's a purpose-built delayed-blowback design proven in decades of international service. The PTR 91 line honors that legacy while keeping things straightforward: solid materials, no unnecessary features, and reliability that doesn't depend on hype.
