Built by Derya Arms of Turkey and imported into the U.S. by Armscor, the TM22-S-18 has been selected as American Riflemans Gun of the Week, and for good reason. This .22-caliber semi-automatic rifle is designed to provide shooters with a lightweight, ergonomic, and affordable rimfire option that balances practical use with innovative features. The first thing many notice about the TM22-S-18 is its synthetic stock. Beyond contributing to the rifles durability, the stock helps keep the overall weight under 5 pounds, making it especially comfortable to carry for long sessions at the range or for small game hunting in the field. The synthetic stock also includes thoughtful touches such as a grippy recoil pad to keep the rifle firmly seated, comb riser mounting slots, and chevron-style texturing on the fore-end to ensure positive handling. Armscor prioritized versatility in this model. The TM22-S-18 is equipped with adjustable front and rear sights, giving shooters a classic option for immediate use. However, it also features a Picatinny rail across the receiver for those who prefer to mount optics. The fore-end cap conceals an additional rail segment, allowing for accessories such as bipods or lights. These modular features position the rifle as both beginner-friendly and adaptable to more experienced shooters looking to tailor their rimfire platform. The rifle feeds from a 10-round detachable box magazine, released by a forward-flicking lever located between the enlarged trigger guard and magazine well. This design promotes fast reloads without sacrificing safety. The crossbolt safety sits conveniently behind the trigger and functions in a straightforward manner, offering confidence for new shooters while maintaining the controls that experienced users expect. Another thoughtful detail is the rifles ambidextrous adaptability. The charging handle can be switched to either side, allowing both right- and left-handed shooters to configure the gun to their preference. Such adaptability is rare in this price range, giving the TM22-S-18 added appeal as a shared family rifle or a training tool in diverse households. During American Riflemans range testing, evaluators found the TM22-S-18s trigger to be surprisingly crisp for its price category. Combined with the adjustable sights, shooters were able to quickly get on target and maintain accuracy at typical rimfire distances. The rear sights flip-up design also allows it to clear low-mounted optics, a detail that reflects the design teams awareness of modern user needs. Testers also noted that the stocks long wrist and textured grip panels accommodate a wide range of hand sizes, making the rifle accessible to younger shooters without sacrificing comfort for adults. With an 18-inch barrel, the TM22-S-18 strikes a balance between accuracy and portability. While it does not include a threaded barrel for suppressor use, it provides features typically unavailable at its modest price point. For many buyers, especially those looking for a reliable plinker or a starter rifle, the cost savings combined with ergonomic design make this rifle a competitive option against better-known rimfire models.
