Video review
Expert review
About this product
The Mauser Rimfire STG-44 is a full-size .22 LR semi-automatic rifle that replicates the classic STG-44 silhouette with modern rimfire functionality. It's built with a 16.3-inch barrel and weighs 9.6 pounds, giving it substantial heft for a training platform. This rifle bridges historical appeal with practical rimfire economics.
What is the Mauser Rimfire STG-44 used for?
This rifle is primarily a training and recreational platform for building muscle memory on a full-sized battle rifle format without the cost of centerfire ammunition. The 9.6-pound weight closely mimics handling characteristics of its centerfire counterparts, and the .22 LR chambering allows for extended range sessions. It's ideal for introducing new shooters to historical firearms or for veterans to maintain proficiency economically.
How does the Mauser Rimfire STG-44 compare to the Stevens 334 Rifle?
The STG-44 offers historical replication and semi-auto functionality where the Stevens 334 in .308 Win provides hunting-ready power and bolt-action precision. The Stevens 334 is better for ethical medium-game hunting at 200+ yards, while the STG-44 excels at high-volume target practice under 100 yards. For training fundamentals on a platform that feels like a battle rifle, the STG-44 has no equal in this price bracket.
What does it weigh and what are the dimensions?
The rifle weighs 9.6 pounds with an overall length of 37.24 inches and a 16.3-inch barrel. This substantial weight provides stability for offhand shooting and closely matches the handling of original military rifles. The balance point sits approximately 12 inches forward of the trigger guard, giving it that characteristic forward-heavy feel of historical battle rifles.
Who is this NOT for?
This rifle is not for hunters needing ethical stopping power beyond 50 yards or competitors seeking match-grade accuracy. The .22 LR cartridge lacks the energy for clean takedowns of game larger than squirrels, and the military-style sights aren't optimized for precision benchrest shooting. If you need sub-MOA accuracy or hunting capability, consider the Stevens 334 in .308 Win instead.
What's in the box?
You get the rifle, one 25-round detachable magazine, and basic safety documentation—no optic mounts or cleaning kits included. The magazine features a durable polymer construction with steel feed lips rated for 5,000+ cycles. You'll need to budget separately for .22 LR ammunition and eye/ear protection before heading to the range.
Is the Mauser Rimfire STG-44 worth it at $523.99?
At $523.99, it represents solid value for shooters specifically seeking historical training platform functionality. Compared to converting an original STG-44 to .22 LR (which can exceed $3,000), this offers 90% of the experience at 17% of the cost. For general plinking, a standard 10/22 might be more practical, but for authentic historical handling, this price is competitive.

Frequently asked questions
- Is it compatible with standard .22 LR ammunition?
- Yes, it cycles standard, high-velocity, and hyper-velocity .22 LR ammunition reliably, but I recommend CCI Mini-Mags for consistent cycling. Avoid subsonic rounds as they may not generate enough pressure to cycle the semi-automatic action properly. The chamber is cut to SAAMI specifications for .22 LR cartridges.
- Does it fit standard STG-44 accessories?
- No, the mounting points and dimensions differ from original STG-44 patterns due to the rimfire action. Aftermarket support is limited primarily to replacement magazines available through Mauser distributors. Don't expect original slings, optics, or bayonets to fit without modification.
- How long does shipping take?
- Firearms ship within 3 business days to your selected FFL dealer after background check clearance. Ground shipping typically adds 5-7 business days depending on your location relative to our Montana warehouse. All shipments require adult signature confirmation at the FFL.
- Can I return it if there are cycling issues?
- Yes, we offer a 30-day function guarantee through Ironclad Armory—if the rifle fails to cycle properly with recommended ammunition, we cover return shipping. Manufacturer defects are handled directly through Mauser's 1-year warranty, which includes parts replacement but not labor costs after 90 days.
