Drop-in, .22 LR target barrel features a premium, button-rifled, chrome moly liner installed in a lightweight aluminum shell to achieve match grade accuracy and reduced weight. Deep, CNC machined flutes help keep barrel weight to 1 lb., plus increase rigidity and overall surface area for improved heat dissipation. Hardcoat anodized surface delivers added strength and abrasion resistance. Versatile, 1-16" twist rifling stabilizes a wide variety of hunting and match ammunition. Installation may require alteration to factory stock.
