Match-Grade Performance Without The Weight Penalty Of Steel
Premium-quality aluminum alloy barrel gives the rigidity, stability, and performance of a steel bull barrel without the excess weight. Lets you build a tack-driving target rifle from an affordable, easy-to-obtain Ruger 10/22 action. Fully machined to precise, match-grade tolerances from exceptionally hard 7075 aluminum billet that's actually stronger than many mild steel alloys, yet gives all the benefits of a thick barrel, including improved heat distribution to resist accuracy changes due to barrel heating. Custom match chamber in .22 LR or .17 HM2, and button-rifled Chromalloy steel liner with precise 1-16" rifling for excellent accuracy, even from 60-grain subsonic .22 LR ammo. Barrel shanks are oversized to .001" and may require minor fitting; .17 HM2 barrel requires a heavy bolt or bolt handle assembly, available separately. Tough, durable, good-looking Cerakote™ ceramic finish resists corrosion, scratches, and surface wear. Recessed target crown protects the rifling at the muzzle. 1/2-28 TPI muzzle threads accept a variety of AR-15/M16 flash hiders and muzzle brakes. .750" diameter barrel accepts standard AR-15/M16 gas blocks for extra mounting options. Factory taper barrel provides a stock 10/22 look, a lightweight package.
