The Mauser STG-44 is a semi-automatic rimfire rifle chambered in .22 LR, styled after the historic World War II-era assault rifle. It has a 16.5-inch barrel, an overall length of 37.25 inches, a wood stock with fixed design, and weighs 9.90 lbs. The steel receiver and manual thumb safety round out a fairly conventional .22 setup dressed in a historically recognizable body.

Detailed Features 

The 16.5-inch barrel strikes a workable balance between handling and sight radius. Semi-auto action handles follow-up shots without drama. Adjustable rear sights let you dial in aim for different distances. The steel receiver and wood stock combination gives the rifle a traditional feel and enough mass to keep it stable during extended range sessions. 
 
At 9.90 lbs it is on the heavier side for a .22 LR, which aids steadiness but can be noticeable during longer outings. The manual thumb safety placement follows conventional layout.

The STG-44 in .22 LR draws interest from two overlapping groups: people who shoot .22s regularly and people who like WWII-era styling. The wood finish and overall silhouette get consistent praise for evoking the original, and history buffs who want a functioning nod to the wartime design seem satisfied with the aesthetics.

Shooting performance is generally reported as solid for the caliber. The semi-auto action runs smoothly, accuracy is adequate for recreational shooting and small game, and the .22 LR cartridge keeps ammunition costs low — a frequently cited advantage.

Build quality opinions are less uniform. Most users are happy with the construction, but some note that fit and finish don't always match higher-end .22 rifles or the quality implied by the Mauser name. Weight — 9.90 lbs — comes up as a point of contention: it adds stability but makes the rifle feel substantial for what is essentially a rimfire plinker.

For new shooters and those teaching firearm fundamentals, the low recoil and manageable operation make it a practical training tool.
