The forged receiver set delivers proven durability and precise fit, while the hard-coat anodized matte black finish resists corrosion and wear.
A 16-inch parkerized chrome-moly barrel provides consistent accuracy and longevity. The 1:7 twist rate stabilizes the full range of 5.56 NATO bullet weights, from light varmint loads to heavier barrier rounds.
The aftermarket multi-port compensator reduces muzzle rise, supporting faster follow-up shots. Because the barrel is threaded, owners can easily swap or remove the device to suit different shooting needs.
The Magpul MOE 6-position stock offers adjustable length of pull, non-slip rubber butt-pad, and ambidextrous QD sling attachment points, giving shooters a comfortable, customizable interface.
A 7-inch polymer ribbed CAR handguard keeps weight down while protecting the shooter’s hand from heat. The flat-top upper with integral Picatinny rail (scope-mount ready) simplifies the addition of optics or back-up sights.
