The Utility series is Anderson Manufacturing's value-driven line, yet this rifle retains a forged 7075-T6 lower and upper receiver with Type III hard-coat anodizing for long-term durability. Anderson's roll mark and Hebron, Kentucky production add collector appeal for those who like U.S.-made builds.
A 16-inch government-profile barrel made from 4150 CrMoV steel is nitride treated inside and out for corrosion resistance. The 1:8 RH twist stabilizes a wide range of 5.56 NATO and .223 Remington bullet weights, and the 1/2-28 muzzle threads come ready for your choice of brake, flash hider, or suppressor mount.
The 15-inch free-float handguard is machined from 6061-T6 aluminum with M-LOK slots at 3, 6, and 9 o'clock and an uninterrupted Picatinny rail on top, giving you ample space for optics, lights, and accessories without barrel contact.
Custom skeletonized furniture from Adaptive Tactical style polymer shaves ounces while providing a positive grip and six-position length-of-pull adjustment (10.5 inches collapsed). QD sling sockets in the end plate and butt-stock simplify carry options.
Inside, a standard M16-profile bolt-carrier group with phosphate/nitride finish runs on a reliable carbine-length direct-impingement gas system, making parts compatibility and future upgrades straightforward.
