The Tactical Solutions PAC-LITE IV upper receiver assembly for Ruger Mark IV .22 LR pistols delivers a lightweight, accurate upgrade path for shooters looking to get more out of their factory platform. This 4.5-inch barrel unit in Olive Drab cuts down on weight while tightening groups and improving overall reliability—all without a trip to a gunsmith. If you run a Mark IV or Mark IV 22/45 frame and want a modern, purpose-built alternative to the factory upper, the PAC-LITE IV gives you precision-grade performance in an easy swap.
Installation is straightforward: the PAC-LITE IV slides onto your existing Ruger frame with no gunsmithing required. The barrel features a 1:16 rate of twist, 11-degree target crown, and an M16 x 28 thread pattern, paired with a stainless steel breech face and receiver for durability. The aluminum barrel and receiver keep overall weight low—just 8.5 ounces—so the gun handles fast and feels balanced in the hand. A thread protector is included, and the assembly ships pre-drilled and tapped for Tactical Solutions scope bases, so mounting optics is plug-and-play.
Whether you're tuning a Mark IV for casual plinking or setting up a dedicated .22 trainer, the PAC-LITE IV is a no-fuss upgrade that genuinely improves the platform. The Olive Drab finish pairs well with modern tactical gear and blends into most environments. This is the kind of bolt-on enhancement that turns a good pistol into one you actually want to shoot.
