Precision Rimfire Performance in a Compact Package

Bring the versatility of .22LR to your AR build with this tapered 4.5″ barrel from AT3™. Crafted from premium 4150 CrMoV steel per MIL-B-11595E specs and protected by a rugged black nitride finish.

The tapered profile trims weight while maintaining accuracy with .22LR ammunition. At just 4.5″ long with 1/2×28 muzzle threads, it’s an ultra-compact option for dedicated .22LR AR uppers or PDW-style pistol builds.

Designed for reliable cycling when paired with the AT3™ .22LR bolt carrier group and Black Dog Machine magazines. This tough little barrel delivers consistent rimfire performance in a space-saving platform.

Overall nice barrel. realistically its 3" after the barrel nut so if you want 4.5 better go with a 7 would be more ideal.
