The Ruger Mark IV 22/45 Lite America’s 250th Anniversary Edition celebrates a historic milestone with a special commemorative engraving marking America’s 250th Anniversary. This limited-edition rimfire pistol combines Ruger’s proven Mark IV platform with modern features designed for accuracy, reliability, and customization, making it an excellent choice for target shooting, training, plinking, and collecting alike.
A standout feature is the 1/2"-28 threaded bull barrel, which includes a thread protector and allows easy attachment of compatible muzzle devices and suppressors where legally permitted. The cold hammer-forged barrel delivers exceptional accuracy and long service life while maintaining the lightweight handling characteristics shooters appreciate.
This model also comes equipped with a factory-installed scope mount, allowing direct installation of popular optics using RMR, DPP, and RMSc footprint patterns. Combined with the adjustable rear sight and fixed front sight, shooters have multiple sighting options for precision shooting.
The Mark IV platform is known for its innovative one-button takedown system, making maintenance and cleaning significantly easier than previous generations. Additional features include an ergonomic polymer grip frame, checkered 1911-style grip panels, ambidextrous manual safety, push-button magazine release, and Ruger’s reliable internal cylindrical bolt design for consistent performance.
Whether purchased as a commemorative firearm, range pistol, or suppressor-ready rimfire trainer, the Mark IV 22/45 Lite offers a premium blend of modern functionality and American heritage.
