TACSOL PAC-LITE Ruger 22LR 4.5" Fluted Barrel - Black

The TACSOL PAC-LITE is a purpose-built replacement barrel for Ruger Mark I, Mark II, Mark III, and 22/45 series .22 LR pistols. At 4.5 inches with a fluted profile, this upgrade transforms the handling and feel of your Ruger—lighter, better balanced, and noticeably more accurate than factory iron. Built from aircraft-grade aluminum, the PAC-LITE barrel strips weight without sacrificing strength, making it the original choice for shooters who want to customize their .22 without a trip to the gunsmith. Installation is straightforward on your existing Ruger frame, no specialized tools required.

The fluted design isn't just cosmetic. Those grooves reduce mass while maintaining rigidity, which translates to improved sight picture and faster target reacquisition, especially useful for precision rimfire work at the range or in the field. The matte black finish keeps glare down and pairs well with tactical or competition setups. Threading is 1/2x28, standard for modern .22 accessories, so you have room to grow your gun's capabilities.

Already drilled and tapped for PAC-LITE scope bases, this barrel integrates seamlessly into the PAC-LITE ecosystem if you want to add optics. A thread protector cap is included, so your muzzle stays protected when you're not running a suppressor or other devices. Whether you're a competition shooter, a precision .22 enthusiast, or someone who simply wants a lighter, faster-handling Ruger, the PAC-LITE barrel delivers real improvements in feel and function.
