The Ruger Mark IV 22/45 Lite .22LR delivers top-tier rimfire performance in a visually striking and easy-to-maintain platform. This model features a black anodized ventilated aluminum receiver paired with a gold-finished tensioned stainless steel barrel, offering a head-turning look and ultra-lightweight feel.
With its 4.4″ threaded barrel (1/2″-28), this pistol is suppressor-ready and perfect for both target shooting and quiet training setups. It includes an optics-ready Picatinny rail on top, allowing for fast and easy red dot mounting. Whether you’re plinking or competing, this setup adapts quickly to your needs.
The 22/45 frame mimics the angle and feel of a 1911 grip and includes checkered panels for positive control. Most notably, the Mark IV series features a one-button takedown, making cleaning and maintenance fast and frustration-free.
