Ruger Mark IV 22/45 | 22 LR | 5.5″ Bull | 40107

The Ruger Mark IV 22/45 pairs the familiar Mark series rimfire action with a 5.50″ bull barrel and a blued finish for a stable, low-recoil shooting platform. The pistol ships with two 10-round magazines and a receiver drilled and tapped for Weaver/Picatinny optics. For a sighting option under $1,000, consider a Vortex Venom red-dot; it complements the drilled-and-tapped receiver and keeps sight acquisition fast for target work.

Recommended uses: target shooting and training; casual plinking and small-bore practice sessions.
