Excel Arms Accelerator MR-22 Stainless 18″ Spiral Fluted – 22 Mag

Precision-Built Rimfire Performance in a Modern Tactical Platform

The Excel Arms Accelerator MR-22 Stainless 18″ Spiral Fluted – .22 Mag is a premium rimfire rifle designed for shooters who demand accuracy, durability, and a sleek tactical profile. Engineered with a stainless steel receiver and a match-quality fluted barrel, the MR-22 delivers exceptional performance for target shooting, varmint control, and high-velocity rimfire applications.

The .22 Magnum chambering offers superior range, flatter trajectories, and higher energy than standard .22LR — making the MR-22 an outstanding choice for shooters who need rimfire precision with extra punch.

Stainless Construction for Long-Lasting Reliability

This rifle’s stainless steel receiver and barrel give it corrosion resistance, strength, and consistent performance in all weather conditions. The standout feature — an 18-inch spiral-fluted stainless barrel — reduces barrel weight, improves cooling, and adds stiffness for accuracy-enhancing harmonics.

The fit, machining, and finish are all engineered for long-term durability and repeatable accuracy.

Semi-Auto Rimfire Power with Smooth Cycling

The MR-22 features a reliable semi-automatic action tuned for the hotter pressures of .22 WMR. It feeds smoothly, cycles consistently, and handles premium hunting/target ammunition with confidence. Paired with its ergonomic stock and balanced feel, it provides easy handling and fast follow-up shots.

• Varmint and predator control
