Browning Buckmark Compensator Matte Black Originally designed for the Browning Buckmark, these Trail-Lite® Compensators are a simple addition to spruce up ANY 1/2"x28 threaded .22LR pistol or rifle. With 360 degree ports, these comps help reduce muzzle flip but also add a little pizazz to your existing platform. They fit flush with Tactical Solutuions Trail-Lite® 1/2"x28 threaded pistol barrels for the Browning Buck Mark pistol. Or, we can install one on your existing factory barrel. Threads: 1/2"x28 Diameter: .900" Diameter Length: 2.63" Long Notes: Barrels need to be threaded to install this compensator. Tactical Solution Trail-Lite® barrels are already threaded.
