The Voidbreaker 16-inch Carbine-Gas 1:7 5.56 NATO AR-15 Freefloat M-Lok Handguard Rifle Full Build Kit from Davidson Defense offers a solid foundation for custom builds. Featuring a 16-inch M4 profile barrel made from durable 4150 CrMoV steel with a phosphate finish, it is chambered in 5.56 NATO and has a 1:7 twist rate for improved accuracy. The carbine-length gas system with a micro low-profile gas block ensures reliable operation.
The upper receiver is constructed from 7075-T6 aluminum with anodized finish, while the 15-inch free-float M-Lok handguard provides versatile mounting options and features a partial Picatinny top rail. An adjustable black nylon reinforced polymer stock, a nitride-finished bolt carrier group, and a Mil-Spec charging handle complete the assembly. The package includes a Mil-Spec heavy-duty 6-position buffer tube and a standard GI birdcage flash hider to optimize performance.
