Tactical Solutions Pac-lite IV Rug Mkiv 22lr 4.5 Gray Upper Replacement

The Tactical Solutions Tacsol Pac-lite IV Rug Mkiv 22lr 4.5 Gray upgrade replaces your factory Ruger Mark IV or Mark IV 22/45 upper to shed weight, boost accuracy, and enhance reliability, making the Ruger platform feel even more responsive in the field or the range. Offered in a 4.5 inch length with a Gun Metal Gray finish, this Pac-Lite assembly features a 1:16 rate of twist, 28 threads, and an 11 degree target crown, delivering consistent shot placement and improved precision in a compact package. The design uses a stainless steel breech face and receiver paired with a lightweight aluminum barrel and receiver to minimize weight—clocking in at about 8.5 ounces—without sacrificing rigidity or durability. Drilled and tapped for Pac-Lite scope bases, with a thread protector end cap included, the setup is ready for optics when you need it, while maintaining quick, tool-free install on your existing MK frame. Ideal for competition, plinking, or field use, Tactical Solutions� Pac-Lite IV upgrade provides a balanced, pro-like feel and reliable performance from a proven platform, transforming your .22 LR handgun into a lighter, more accurate choice.
