Mauser M-15 SD .22 LR Semi-Auto Rifle
About this product
The Mauser M-15 SD is a .22 LR semi-automatic rimfire rifle with tactical styling designed for cost-effective training and recreational shooting. Built on a steel receiver with a synthetic stock, it bridges the gap between plinking fun and serious muscle-memory development. At 295.99 USD, it offers suppressed-range aesthetics without the NFA paperwork.
What is the Mauser M-15 SD used for?
The M-15 SD is primarily a training and recreational rimfire rifle. Its .22 LR chambering makes it ideal for high-volume shooting sessions where centerfire ammunition costs would be prohibitive. The side-folding stock and adjustable cheek rest allow it to mimic the handling of larger tactical platforms while keeping operational expenses under 5 cents per round.
How does the Mauser M-15 SD compare to the Stevens 334?
The M-15 SD is better for rapid-fire training, while the Stevens 334 is superior for precision. The M-15's semi-automatic action allows for fast follow-up shots, but the Stevens 334 bolt-action rifle in .308 Win delivers sub-MOA accuracy the rimfire can't match. Choose the M-15 for trigger time economy, the 334 for hunting or long-range work.
What does it weigh and what are the dimensions?
The rifle weighs 5.8 pounds and measures 35.5 inches long with the stock extended. With the side-folding stock collapsed, the length drops to 25 inches for storage. The 16.5-inch barrel contributes to the overall balance, making it noticeably handier than a full-size Stevens 555 shotgun when moving between shooting positions.
Who is this NOT for?
This rifle is not for hunters needing ethical stopping power beyond small game. The .22 LR cartridge lacks the energy for anything larger than rabbits or squirrels at reasonable distances. Serious competitors requiring match-grade accuracy should also look elsewhere, as the platform is designed for reliability and familiarity training rather than tight group shooting.
What's in the box?
The rifle ships with flip-up front and rear sights installed and one 10-round magazine. There are no additional accessories or optics included, keeping the initial cost down. The faux suppressor is permanently attached, measuring 2 inches in length and bringing the total barrel assembly to the non-NFA-required 16.5 inches.
Is the Mauser M-15 SD worth it at $295.99?
At under $300, the M-15 SD delivers solid value for tactical-style rimfire training. The steel receiver construction and functional folding stock justify the price point compared to basic .22 rifles. For shooters wanting to practice manipulations without burning through expensive centerfire ammunition, this platform pays for itself within the first 1,000 rounds of training.

Frequently asked questions
- Is the faux suppressor removable?
- No, the faux suppressor is permanently attached to the 16.5-inch barrel to maintain a non-NFA overall length. Attempting removal would require professional gunsmithing and likely violate federal firearm regulations. The unit is purely cosmetic and provides no sound suppression.
- What magazines does it use?
- The M-15 SD uses proprietary 10-round rotary magazines specific to the Mauser M-15 platform. Aftermarket options are limited compared to more common .22 LR patterns like the Ruger 10/22. Spare magazines typically retail for $25-30 each from Mauser distributors.
- Does it have optics mounting capability?
- Yes, the steel receiver includes a standard 11mm dovetail for rimfire scopes and red dot sights. The mounting surface provides solid placement for optics weighing up to 12 ounces without affecting cycling reliability. The flip-up sights can co-witness with low-profile optics.
- Can left-handed shooters use this rifle?
- The safety and controls are configured for right-handed operation only. Left-handed shooters would need to adapt their grip to manipulate the thumb safety on the right side of the receiver. Ejection port placement may cause brass deflection concerns for southpaws.
