The Mauser M-15 SD is a .22LR semi-auto rifle built for shooters who want a nimble, accurate platform for training, plinking, or small-game hunting. This is a purpose-built .22 that doesn't waste your time or money on unnecessary bulk—just straightforward rimfire performance in a package that handles like a centerfire rifle. The 16.5-inch barrel keeps things compact without sacrificing the velocity needed for reliable function, and at 6.45 lbs, it won't wear you out during a long day at the range or in the field.
The M-15 SD comes fitted with a railed handguard and an optical sight rail, so you can mount your preferred optic or red dot without extra adapters. The 22-round proprietary magazine keeps you in the action longer between reloads—especially useful if you're training or working through a stack of targets. The three-position folding stock gives you flexibility to adjust length of pull or collapse the gun for storage and transport, and the overall length ranges from 34.65 to 36.06 inches depending on stock position. A faux suppressor is included, adding a bit of visual appeal while keeping the muzzle signature consistent.
Whether you're introducing a new shooter to the fundamentals, zeroing a centerfire rifle platform, or just enjoying a day of low-recoil, low-cost shooting, the M-15 SD delivers the accuracy and reliability Mauser is known for. The bronze-black finish resists corrosion, and the modular design means you can tune it to your preferences as your needs evolve.
