Barska Barrel Quad Rail AW11714 is an easy to install method of mounting multiple accessories to the barrel of your rifle, shotgun, or other firearm. Built from tough aluminum, these Barska mounts use four screws to securely attach to your rifle's barrel, resulting in a recoil-resistant platform for all your weapon accessories. Barska has designed the Barska Barrel Clamp Quad Picatinny Rail with a four-slot Picatinny rail system on all four sides of the barrel, allowing you to combine a laser sight with a flashlight, a red dot sight with a vertical grip, or any other accessory combination you'd like to use. The rail system is only a little more than an inch long, and its black matte finish looks great and won't reflect sunlight. Evolve your favorite firearms with the compact mounting platform that is the Barska Barrel Aluminum Quad Rail System.
