Driven by the demands of combat every component was re-engineered to be lighter yet stronger. The result? A high-performance rifle that weighs five pounds less than the original M107 but is every bit as tough. - Designed to be used with a suppressor this one-of-a-kind rifle allows you to combine signature reduction capabilities with the flawless reliability of the original Barrett M107 but with a rifle weight reduction of 5 pounds. An all new bolt carrier group has been designed and is key to making the rifle suppressor-ready. Its steel four-port cylindrical muzzle brake is engineered to work seamlessly with a quick-attach Barrett QDL Suppressor. - The lightweight aluminum upper receiver features an integrated 27 MOA optics rail. Inside the upper receiver the bolt carrier rides on a hardened steel anti-wear strip for added durability. A thermal-guard cheek piece protects the user's face from extreme heat or cold. - Advanced design and manufacturing make the M107A1 more precise than ever. The rear barrel stop and front barrel bushing are bolted and bonded with a high strength compound. A titanium barrel key and fully-chrome-lined bore and chamber add to the rifle's durability. - Enhanced modularity is also a key feature of the M107A1. The rail-mounted aluminum rear grip can easily be reconfigured. The newly designed titanium and polymer monopod is adjustable from either side. - The M107A1 rifle's lower receiver includes a new aluminum recoil buffer system that's optimized for use with the Barrett QDL Suppressor. The bolt carrier's components are protected with a mix of ultra-hard coatings and advanced nickel Teflon plating that increases lubricity is corrosion-resistant and greatly eases cleaning. - Numbered witness holes on the magazine are just another example of how even the smallest detail makes a powerful difference.
