Why Choose the PAC-LITE® 4.50" Featherweight handling: Aluminum outer shaves ounces off the muzzle for faster transitions, quicker recoveries, and less fatigue during long sessions. Match-grade precision: Steel-lined bore and tight chambering support excellent accuracy with quality .22 LR ammunition. Threaded muzzle: Run a rimfire suppressor, compensator, or protector (where legal) to tune recoil impulse and reduce muzzle rise. Optic-ready: Drilled & tapped for popular pistol optics bases; mount a red dot to speed up dot-to-target time. Adjustable sights included: Dial your elevation and windage with the installed irons—perfect as a backup to your dot. Durable black anodized finish: Low-glare, wear-resistant exterior stands up to holster use, range bags, and match abuse. Direct fit for Ruger platforms: Designed to upgrade Ruger Mark I/II/III & 22/45 frames with a proven, easy-to-install system (professional fitting recommended for best results). Performance You’ll Feel Faster sight picture: Short 4.50" length and lighter nose make it easy to present from low ready or holster and settle on target. Cleaner dot tracking: Reduced reciprocating weight and optimal balance help maintain a stable window on micro red dots. Suppressor synergy: Threaded muzzle pairs perfectly with rimfire cans for quieter training and better shot calling (where permitted). Ideal Uses Steel challenge & speed games: Light, quick, and accurate for rapid transitions. Small-game & field carry: Compact, maneuverable package for woods walking (where legal and appropriate). Precision plinking & training: Build fundamentals with a controllable, accurate rimfire pistol. Installation & Setup Tips Safety first: Ensure the pistol is unloaded; remove the old upper per Ruger instructions. Fit the PAC-LITE® upper: Align, seat, and follow torque/assembly guidelines. Add accessories: Install suppressor/comp (verify concentricity) and your optic base/optic if desired. Zero both sighting systems: Confirm iron-sight zero first, then mount and zero your red dot. Ammo testing: .22 LR is load-sensitive—try several SKUs to find your pistol’s best group.
