Designed to be used with a suppressor this oneofakind 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 thermalguard cheek piece protects the users face from extreme heat or cold. The rear barrel stop and front barrel bushing are bolted and bonded with a high strength compound. A titanium barrel key and fullychromelined bore and chamber add to the rifles durability. The newly designed titanium and polymer monopod is adjustable from either side. The M107A1 rifles lower receiver includes an aluminum recoil buffer system thats optimized for use with the Barrett QDL Suppressor. The bolt carriers 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.
