Pac-Lite IV Barrel fits Ruger MKIV and MKIV 22/45, Non Fluted, 4.5"-FFL Required

Pac-Lite IV Barrel fits Ruger MKIV and MKIV 22/45, Non Fluted, 4.5"

Upgrade your Ruger® Mark IV™ or Mark IV 22/45™ pistol with the TacSol PAC‑LITE IV® Barrel, an ultra‑lightweight, precision‑machined barrel designed to deliver exceptional accuracy and fast, responsive handling. Built from billet 6061‑T6 aluminum with a durable hard‑anodized finish, the PAC‑LITE IV offers the performance, reliability, and craftsmanship that have made TacSol a leader in .22LR barrel innovation.

Hand‑chambered for .22 LR and equipped with an 11‑degree target crown and chromoly steel bore, this barrel upgrade provides outstanding consistency and precision. The threaded muzzle (½x28) makes it easy to attach suppressors or compensators, and the barrel is drilled and tapped for optics. Choose from fluted or non‑fluted designs and 4.5" or 6" lengths to match your preferred balance and shooting style.

Weighing just 8.8–10.2 oz, the PAC‑LITE IV dramatically reduces front‑end weight, making it ideal for plinking, target shooting, and small‑game hunting. Installation is simple, and a 4473 is required.
