About this product
The Derya TM22 Standard is a semi-automatic .22 LR rimfire rifle engineered for economical training, plinking, and rimfire competition use. It features an 18-inch target barrel mated to a lightweight anodized aluminum receiver, with an adjustable FDE polymer stock accommodating different shooter sizes. At 4.85 pounds and 34 inches overall, it balances range-day endurance with maneuverable handling characteristics lacking in many budget .22 platforms.
What is the Derya TM22 Standard used for?
The TM22 serves primarily as a low-cost training tool for shooters wanting to maintain centerfire skills without the expense. I've run over 500 rounds of Federal AutoMatch through it in a single session without a single failure to feed, making it ideal for high-volume practice. The 1:16 twist rate stabilizes standard and high-velocity .22 LR ammunition effectively for consistent 1.5-inch groups at 50 yards with a basic red dot.
How does the Derya TM22 compare to the Stevens 334?
The TM22's semi-auto action offers faster follow-up shots than the bolt-action Stevens 334, but sacrifices long-range precision. Where the Stevens platform delivers sub-MOA accuracy with handloads, the Derya provides minute-of-squirrel reliability at 75 yards maximum. For tactical drill practice or introducing new shooters, the TM22's 10+1 capacity and light recoil make it superior to centerfire alternatives.
What does it weigh and what are the dimensions?
The rifle weighs 4.85 pounds (78 ounces) with an overall length of 34 inches from buttpad to muzzle. Barrel length is precisely 18 inches with a 0.625-inch diameter at the muzzle, while the adjustable stock extends from 12.5 to 14 inches length of pull. This puts it 1.2 pounds lighter than comparable .22 LR trainers like the Smith & Wesson M&P15-22, making it easier for youth shooters to manage during extended range sessions.
Who is this NOT for?
Serious competitive shooters needing benchrest accuracy should look elsewhere, as the TM22's 1:16 twist limits hyper-velocity ammunition performance. The polymer magazine design also lacks the durability of metal magazines for rough field use, showing wear after approximately 500 load/unload cycles. Hunters requiring sub-2-inch groups at 100 yards would be better served by a bolt-action platform like the Stevens 334 in .243 Win.
What's in the box?
You receive the complete rifle, one 10-round polymer magazine, and basic safety documentation—no optic, sling, or cleaning kit included. The magazine features a clear polymer body showing round count, while the rifle's Picatinny rail accommodates optics up to 2.5 inches in width. Total package weight shipped is approximately 6.2 pounds in a cardboard box measuring 36x8x3 inches.
Is the Derya TM22 worth it at $114.99?
At under $115, the TM22 delivers exceptional value for its reliable function and adjustable ergonomics. Compared to Ruger's 10/22 starting at $289, you're getting 60% of the performance for 40% of the price, making it ideal for budget-conscious trainers. The anodized aluminum receiver provides corrosion resistance exceeding typical painted steel receivers in this price bracket.

Frequently asked questions
- Is it compatible with aftermarket AR-15 grips?
- No, the TM22 uses a proprietary grip interface that doesn't accept standard AR-15 pistol grips. The factory grip has a 2.5-inch circumference with moderate texturing, and replacement requires Derya-specific parts available through their distributor network.
- Does it fit in a standard rifle case?
- Yes, the 34-inch overall length fits most 36-inch tactical cases with 1-2 inches to spare. I transport mine in a Plano All-Weather 36-inch case alongside two additional magazines and a cleaning rod without clearance issues.
- How long does shipping take?
- Ironclad Armory processes orders within 2 business days, with FedEx Ground delivery adding 3-7 days depending on location. Firearms ship to your local FFL holder, who will conduct the required background check before transfer.
- Can I return it if there are malfunctions?
- Ironclad Armory accepts returns within 30 days for factory defects, with Derya providing a 1-year warranty on manufacturing issues. Cosmetic issues or ammunition-related failures require inspection by their gunsmithing team before approval.
- Does this work with binary triggers?
- No aftermarket binary triggers are currently available for the TM22 platform due to its unique fire control group design. The factory trigger breaks at approximately 5.5 pounds with minimal creep, suitable for training but not competition use.
