Tactical Solutions Pac-Lite 6" Threaded Barrel 22 LR - Black Anodized for Ruger Mark I/II/III & 22/45

The Tactical Solutions Pac-Lite 6" Threaded Barrel for Ruger Mark I/II/III and 22/45 pistols is a lightweight, threaded replacement barrel built for shooters who want genuine accuracy and suppressor-ready capability out of the box. Hand-chambered in .22 LR with a target crown and chromoly steel bore, this barrel delivers the precision you'd expect from TacSol's reputation in the .22 LR aftermarket—without the weight penalty. At just 8.6 ounces, the Pac-Lite is designed to be swapped in without gunsmithing, making it an ideal upgrade for plinkers, target shooters, and hunters who want a more accurate, more versatile Mark pistol.

The 6-inch length and 1.00" target diameter give you a clean platform whether you're running it bare or threading on a suppressor or compensator. The muzzle is threaded at 1/2" x 28, the standard for rimfire silencers, so you've got plenty of options for hearing protection on the range or in the field. The barrel comes drilled and tapped for an optic rail, so adding a red dot or low-power scope is straightforward. Black anodized aluminum construction keeps things tough and lightweight, and the 1-in-16 twist rate is optimized for .22 LR rounds across the typical velocity range.

Installation is genuinely simple—no special tools or smith work required. Tactical Solutions includes ramped front sight as standard, and the whole assembly cycles smoothly thanks to the design of the bolt interaction. Whether you're looking to tune an existing Mark pistol for competition, add a suppressor-ready option to your plinker, or just squeeze more accuracy from a favorite shooter, the Pac-Lite addresses what matters: weight, precision, and ease of use.
