The AT3 16-inch barrel is crafted from premium 4150 CrMoV steel per MIL-B-11595E specs with black nitride finish for durability and corrosion resistance. The lightweight pencil profile keeps weight down while maintaining accuracy with 22LR ammunition, and the 1:16 twist rate is optimized for standard 22LR loads. At 16 inches long with 1/2×28 muzzle threads, this barrel delivers the full velocity potential of 22LR while keeping the overall build lightweight and easy to handle.
The included AT3 stainless steel 22LR bolt carrier group is machined to exact tolerances for reliable cycling with 22LR ammunition. Designed specifically for use with AT3 22LR barrels and Black Dog Machine magazines, this BCG delivers consistent performance in dedicated 22LR builds. The 25-round Black Dog Machine magazine features innovative sonic-welded polymer construction for durability and lightweight performance. This kit gives you everything you need to experience the joy of full-length 22LR shooting at a fraction of the cost of centerfire ammunition.
