Product Description The Tactical Solutions PAC-LITE TSS is a lightweight, precision-engineered integrally suppressed pistol upper for the Ruger Mark I, Mark II, Mark III, and 22/45 series pistols. Chambered in .22 Long Rifle, this Class III NFA item integrates the silencer directly within the barrel assembly, keeping your overall firearm length short and manageable compared to traditional barrels fitted with screw-on suppressors. The upper features an aluminum receiver, titanium baffles, and a stainless steel split tube, delivering an exceptional balance of durability and minimal weight at just 11 ounces. A chromoly steel bore with a target crown ensures pinpoint accuracy, while the patent-pending fiber optic front sight and fully adjustable rear sight allow confident shooting with or without optics. Installation requires no gunsmithing, and the design supports easy disassembly and cleaning for long-term silencer maintenance. Drilled and tapped for a scope rail, the PAC-LITE TSS is the ultimate suppressed rimfire upper for hunting, plinking, and target shooting. Note: This is an NFA-regulated item. A tax stamp is required for purchase and transfer.
