Tactical Solutions Pac-Lite 6" Threaded Barrel for Ruger Mark IV & 22/45 - Black Anodized, Adjustable Sights, 22 LR$286.69
Availability: In Stock
The Tactical Solutions Pac-Lite 6" threaded and fluted barrel for Ruger Mark IV and 22/45 platforms is a lightweight upgrade engineered for shooters who want to dial in accuracy without the weight penalty of factory uppers. Built from aluminum with a stainless steel breech face, this 6-inch barrel cuts down on overall mass—tipping the scales at just 9.5 ounces—while the fluting and 11-degree target crown work together to improve shot placement. If you run a Mark IV or 22/45 and spend time at the range or in small-game hunting scenarios, this barrel swap delivers noticeable handling improvements and tighter groups without requiring a gunsmith to install.
Installation is straightforward—the Pac-Lite upper replaces your factory upper on your existing Mark IV or 22/45 frame with no special tools needed. The 1:16 twist rate is optimized for standard .22 LR ammunition, and the threaded muzzle (1/2 x 28) opens up suppressor options if you're looking to run quiet. The barrel comes threaded and ready to mount Pac-Lite scope bases, with a thread protector (end cap) included to keep the crown protected when you're not suppressed. Black anodized finish stands up to regular handling and provides a clean, no-fuss aesthetic.
Whether you're dialing in a precision .22 setup for target work, hunting small game, or just want a more balanced Mark IV platform, the Pac-Lite barrel gives you measurable improvements in weight distribution and accuracy at a fraction of the cost of a new pistol. The aluminum-and-stainless construction keeps things light while the stainless breech face ensures reliability through thousands of rounds.
