The Tactical Solutions Pac-Lite 6" threaded barrel for Ruger Mark IV and 22/45 is a lightweight upgrade that transforms your .22 LR pistol into a faster, more accurate shooter without requiring gunsmith installation. Built from aluminum for reduced weight while maintaining a stainless steel breech face and receiver, this 6-inch barrel assembly drops onto your existing Ruger frame and is ready to shoot. Whether you're running rimfire competitions, zeroing optics, or just plinking with precision, the Pac-Lite design lets you handle your pistol longer with less fatigue while the 1:16" twist and 11-degree target crown consistently deliver tight groups downrange.
At just 9.5 ounces, the Pac-Lite cuts significant weight from your platform, and the threaded muzzle gives you flexibility to run a suppressor or thread protector based on your setup. The barrel comes drilled and tapped for Pac-Lite scope bases, so mounting optics for extended-range work or competitive shooting is straightforward. The included thread protector keeps the 1/2" x 28 threads clean until you're ready to add your can or other muzzle device.
Installation is genuinely simple—no gunsmith needed. The barrel swap is a straightforward job on the Ruger platform, making this one of the easiest ways to lighten your gun and sharpen your accuracy in one move. The black anodized finish is durable and pairs cleanly with both tactical and classic Ruger builds.
