Volquartsen MK IV, .22LR, 3.5" Barrel, 2-10rd Magazines, Optics Ready, Pistol

The Volquartsen MK IV .22LR 3.5" pistol represents a purpose-built evolution of the rimfire performance platform. Built around Volquartsen’s advanced lightweight carbon fiber barrel technology—refined from their legendary 10/22 upgrades—this pistol is engineered for serious shooters who demand durability, precision, and heat management in a compact configuration. At its core is a stainless steel barrel featuring a laser-hardened breech face, designed to withstand extreme round counts exceeding 100,000 rounds without compromise. Surrounding the barrel is a woven carbon fiber sleeve that enhances rigidity while maintaining an air gap for superior heat dissipation. The result is a lightweight, balanced rimfire pistol that stays consistent through extended range sessions or competition use. This upper is threaded into a Ruger MK IV receiver and paired with an upgraded Ruger MK IV 22/45 frame and Volquartsen Competition Bolt, delivering smoother cycling, enhanced reliability, and refined performance across a wide range of .22LR ammunition. With optics-ready capability and two 10-round magazines included, it’s ready for steel challenge, training, or precision plinking right out of the box.
