Designed as an update to the iconic Barrett M82A1, the M107A1 largely retains the same appearance while maintaining the platform's powerful chambering and long range capabilities. The M107 was also designed to be four pounds lighter than the M82 through the use of titanium construction for some of the internal parts. Fitted with a redesigned four chamber muzzle brake, which acts as a mount for Barrett's QDL line of .50 BMG suppressors. Features flip up blade front and fully adjustable rear peep sights, ventilated steel upper and lower receivers, 60 slot monolithic Picatinny rail running across the upper receiver, A2 pattern pistol grip, folding detachable bipod, polymer cheek rest on the metal stock, and solid rubber recoil pad. Includes a Leupold Mark 5 5-25x56 mm Front Focal scope on a "WARNE" base, 60 rounds of American Eagle XM33 660 grain FMJ, 20 rounds of PMC 660 grain FMJ-BT, and 50 rounds of Hornady 750 grain A-MAX .50 BMG ammunition in factory boxes.

Excellent overall, retaining 99% original matte black finish retained with light cycling wear on the barrel just forward of the upper receiver, carbon buildup within the muzzle brake, and light spotting on the two screws which attach the front sling loop to the upper receiver. The scope is also excellent with some scuffs on the focus knob and crisp optics. Mechanically excellent.
