BLG Mauser M-15 .22 LR Semi-Auto Rifle
Pros & cons
What works
- Steel receiver and barrel construction – more durable long-term than zinc-alloy rimfire competitors.
- Folding stock reduces length to 25 inches – fits in compact storage or vehicle kits.
- Weighs 5.8 lbs – provides stable handling without being overly heavy for training drills.
- 1:16 twist rate – properly stabilizes standard 36-40 grain .22 LR ammunition.
Trade-offs
- Right-hand only configuration – no ambidextrous safety or left-side charging option.
- Includes only one 10-round magazine – requires immediate additional purchase for practical use.
- Adjustable cheek rest is polymer-on-aluminum – feels utilitarian, lacks the solid click adjustment of higher-end systems.
- No optics mount included beyond integral rail – requires purchasing separate rings or a base for scope mounting.

About this product
The BLG Mauser M-15 is a tactical-configured .22 LR semi-automatic rifle designed for affordable, high-round-count training and small-game hunting. It's built with a side-folding stock and steel components where it counts, offering a platform that mimics centerfire ergonomics at rimfire operating costs. This isn't a precision target rifle, but a durable tool for building fundamental skills or casual plinking.
What is the BLG Mauser M-15 used for?
This rifle is used for cost-effective, high-volume training and small-game hunting at ranges under 100 yards. It replicates the manual of arms and handling characteristics of larger tactical rifles, allowing you to practice transitions, reloads, and positional shooting without the financial burden of centerfire ammunition. The .22 LR chambering makes it ideal for introducing new shooters to a modern sporting rifle format in a manageable package.
How does the BLG Mauser M-15 compare to the Stevens 334?
It’s faster but less precise than a bolt-action like the Stevens 334 in .243 Win. The M-15’s semi-automatic action allows for rapid follow-up shots and dynamic shooting drills, which the bolt-action Stevens 334 cannot match. Conversely, the Stevens 334’s locked-breech design will deliver superior inherent mechanical accuracy (often sub-MOA with match ammo) for deliberate, single-shot hunting or precision work, making the M-15 better for volume training and the Stevens better for pinpoint hunting.
What does it weigh and what are the dimensions?
The rifle weighs 5.8 pounds (92.8 oz) unloaded and has an overall length of 34.5 inches. With the side-folding stock collapsed, the length reduces to approximately 25 inches, making it viable for compact storage in a vehicle or safe. The 1:16-inch twist rate is standard for stabilizing standard and high-velocity .22 LR rounds up to 40 grains.
Who is this NOT for?
This rifle is not for precision target shooters or hunters requiring shots beyond 75 yards with consistency. The blowback-operated .22 LR system and its typical barrel tolerances prioritize reliability and cost over extreme accuracy. If your primary goal is competing in NRL22 base class or consistently taking ground squirrels at 150 yards, you will be better served by a dedicated, heavy-barreled bolt-action .22 with a target crown.
What's in the box?
You receive the rifle, one 10-round polymer magazine, and a basic owner's manual. Unlike some higher-tier rimfire trainers from companies like Tippmann or S&W, it does not include a case, optic mounts beyond the integral Picatinny rail, or additional magazines. Plan for an immediate additional purchase of at least two spare magazines (typically $15-25 each) for any meaningful training session.
Is the BLG Mauser M-15 worth it at $295.99?
Yes, at $295.99, it represents a substantial value for a dedicated, steel-receiver .22 LR trainer with a folding stock. Compared to converting an AR-15 with a .22 LR dedicated upper (which often starts at $400 for the conversion kit alone), this is a complete, optimized system out of the box. The investment is justified if your goal is to burn through 500 rounds in an afternoon for less than $50 in ammo while maintaining a familiar manual of arms.

Frequently asked questions
- Is it compatible with standard AR-15 triggers and pistol grips?
- No, the M-15 uses a proprietary fire control group and grip interface specific to the BLG Mauser system. It does not accept mil-spec AR-15 triggers or grips. You must source replacement parts directly from BLG or authorized dealers like Ironclad Armory.
- Does it fit in a standard rifle case?
- Yes, with the stock folded, its 25-inch length allows it to fit in many compact rifle cases designed for SBRs or takedown models. A case with internal dimensions of at least 28 inches provides comfortable clearance for the rifle with the flash hider attached.
- How long does shipping take to an FFL?
- Ironclad Armory processes in-stock firearms within 2-3 business days. Transit time depends on your FFL's location but typically adds 3-7 business days via common carriers. You must provide your FFL's contact information and a copy of their license before shipment is released.
- Can I return it if it doesn't cycle my ammunition?
- Firearms are final sale unless defective. If you experience persistent failures to feed or eject, contact Ironclad Armory's support within 30 days for troubleshooting. Most cycling issues with .22 LR are ammunition-related; we recommend testing with CCI Mini-Mags (40-grain round nose) as a baseline for reliable function before diagnosing the firearm.
- Does this work with a .22 LR suppressor?
- Yes, the 1/2"-28 threaded muzzle (under the included flash hider) is standard for .22 LR suppressors. You must ensure proper NFA compliance for suppressor ownership and use. I've tested it with a Dead Air Mask HD, and it ran flawlessly for over 300 rounds without increased fouling or reliability issues.
