Ruger America's 250th Anniversary Edition Mark IV™ 22/45™
.22 LR Pistol 4.4" Threaded Bull Barrel - 10 Rd

Commemorating a historic landmark in American freedom, the Ruger Mark IV 22/45 Threaded Bull Barrel .22 LR Semi-Automatic Pistol (UPC 7-36676-40194-9) pairs classic target accuracy and modern optic versatility with iconic 1911-style ergonomics. Built on an alloy steel receiver with a rich blued finish and a black polymer 22/45 grip frame, this special collector's model features an exclusive "Made in the 250th Year of American Liberty" laser engraving directly on the barrel. Weighing 33.3 ounces, the added mass of the steel receiver and heavy cold hammer-forged target barrel provides exceptional sight stability, minimal felt recoil, and fast target re-acquisition.

Engineered for unmatched user convenience, the Mark IV features Ruger's simple one-button takedown mechanism that allows the barrel-receiver assembly to tilt up and off the grip frame without tools for quick, proper chamber-to-muzzle cleaning. The 4.40-inch cold hammer-forged bull barrel comes pre-threaded in 1/2"-28 TPI with a thread protector for seamless mounting of popular rimfire suppressors and compensators. Outfitted with a factory-installed scope mount engineered for direct mounting of RMR, DeltaPoint Pro (DPP), and RMSc pattern micro red dots, the pistol also includes traditional iron sights, an internal cylindrical bolt design for permanent sight alignment, an ambidextrous manual safety, and two 10-round magazines.
