It may be related to the Model 82A1/M107, but the M107A1 is far from a simple evolution. Designed to be used with a suppressor, the one-of-a-kind Barrett M107A1 allows shooters 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'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.
This package come with a Leupold Mark 4 M1 scope mounted on Barrett Ultra High Rings and the Barrett Optical Ranging System (BORS), an integrated ballistic computer that mounts directly on the rifle-scope and couples with the elevation knob. The BORS measures air temperature, barometric pressure, and bore line angle automatically, providing the shooter an exact yardage at which the bullet will hit. Once the distance to the target is known, the computer is put into action by simply turning the elevation knob until the LCD displays the target's range. It can be adjusted manually for different cartridges/loads and eliminates the need for counting clicks, allowing the shooter to return to tactical concerns. Barrett's BORS kit includes the Barrett Ballistic PC Software and a data cable that allows the user to program custom loads on their personal computer and transfer them directly to their BORS. Adjustable bipod, monopod, 10-round magazine, and hard carrying case included.
