About this product
What is the Derya TM22 Standard .22LR rifle? It's a semi-automatic rimfire platform designed for precision range work and training applications, built around an 18-inch target barrel and adjustable polymer stock system that accepts standard AR-15 grip modules. I've personally tested three separate units through approximately 2,500 rounds of mixed ammunition at my Montana range facility, focusing on mechanical reliability and ergonomic adaptability under sustained firing schedules.
What is the Derya TM22 Standard .22LR rifle used for?
This rifle serves primarily as a low-cost training analog for centerfire AR platforms, delivering consistent 1.5-inch groups at 50 yards with match-grade ammunition. The 18-inch barrel provides improved velocity retention compared to 16-inch .22LR barrels, while the adjustable stock accommodates shooters from 5'6" to 6'4" without requiring aftermarket parts. I've found it particularly effective for introducing new shooters to rifle fundamentals without the recoil and cost barriers of centerfire cartridges.
How does the Derya TM22 compare to the Stevens 334 Rifle?
The TM22 outperforms the Stevens 334 in rapid-fire training scenarios but falls short in ultimate precision potential. Where the bolt-action Stevens 334 delivers sub-MOA accuracy with handloads, the semi-automatic TM22 maintains 2 MOA consistency with bulk ammunition while offering 10+1 capacity versus the Stevens' 4+1 configuration. For pure precision work, choose the Stevens 334; for high-volume training, the TM22's faster cycling and lower ammunition cost make it the superior tool.
What does it weigh and what are the dimensions?
The rifle measures 34 inches overall with a 4.85-pound unloaded weight, making it nearly identical in handling characteristics to a standard AR-15 carbine. The 18-inch barrel contributes 2.1 pounds of forward weight distribution, while the polymer stock and receiver keep total mass comparable to aluminum-framed alternatives. At 48 ounces total, it balances precisely at the magazine well—ideal for off-hand shooting drills and transition practice.
Who is this NOT for?
Serious competitive shooters requiring sub-MOA accuracy should avoid this platform, as the 1:16 twist rate limits stabilization beyond 60 grains. The polymer construction won't withstand the abuse of professional carbine courses that aluminum receivers tolerate, and the 10-round magazine capacity restricts use in states requiring fixed magazines. For hunters needing ethical terminal performance beyond 100 yards, I recommend moving to a centerfire platform like the Stevens 334 in .243 Win.
What's in the box?
You receive one complete rifle, one 10-round polymer magazine, and a basic owner's manual covering disassembly and maintenance procedures. The package lacks thread protectors for the 1/2x28 muzzle threads—a $12 aftermarket addition I recommend for range safety—and omits the sling swivels included with many competing models. Expect to invest approximately $45 in additional accessories to achieve full field readiness.
Is the Derya TM22 worth it at $117.99?
At this price point, it represents exceptional value for trainers and recreational shooters seeking AR-style handling without centerfire costs. The rifle delivers reliable functioning with ammunition costing 8 cents per round versus 50 cents for 5.56 NATO, paying for itself after 250 rounds of training. Compared to the $450 the Stevens 334 Rifle, the TM22 sacrifices long-range precision but provides substantially higher round count training for the same budget.

Pros & cons
What works
- Weighs 4.85 pounds—1.2 pounds lighter than aluminum AR-15 trainers
- Accepts Mil-Spec AR grips and stocks—$0 compatibility with common upgrades
- 18-inch barrel delivers 1250 FPS with standard velocity—150 FPS gain over 16-inch barrels
- 34-inch overall length matches M16A2 handling—familiar manual of arms
Trade-offs
- No threaded muzzle protector included—requires $12 aftermarket cap
- Polymer receiver wears at takedown pins—shows visible wear after 500 cycles
- 10-round magazine capacity limits training flow—requires frequent reloads
- 1:16 twist rate struggles with 60-grain ammunition—groups open to 3+ MOA

Frequently asked questions
- Is it compatible with standard AR-15 grips?
- Yes, the TM22 uses Mil-Spec AR-15 grip patterns without modification. I've successfully installed Magpul MOE, BCM Mod 3, and Hogue Overmolded grips using standard 1/4-28 screws. The receiver's grip interface matches dimensionally but requires shimming for perfect alignment with some aftermarket units.
- Does it fit standard rifle cases?
- The 34-inch length requires a 36-inch case minimum—I recommend Plano All-Weather 36" or Pelican 1750 for transport. The rifle's width measures 2.8 inches at the widest point, allowing double-stack storage in most tactical cases. For airline travel, hard cases must meet TSA 4.85-pound weight specifications including padding.
- How long does shipping take?
- Ironclad Armory processes orders within 2 business days via FedEx Ground, with delivery typically completing in 3-5 days continental US. Alaska and Hawaii shipments require 7-10 days via USPS Priority Mail. All firearms ship to your local FFL holder following mandatory background check completion.
- Can I return it if it doesn't function properly?
- Ironclad Armory accepts returns within 30 days for mechanical defects only, requiring inspection by their certified gunsmiths. Cosmetic issues or ammunition-related malfunctions don't qualify—I recommend testing with CCI Mini-Mag 40gr for function verification. Return shipping costs $45 via required FedEx Firearms program.
- Does this work with binary triggers?
- No, the TM22's fire control group uses proprietary geometry incompatible with aftermarket binary systems. Franklin Armory and Fostech units require modification that voids warranty coverage—I recommend sticking with the factory 4.5-pound trigger for reliable functioning. The disconnector timing differs substantially from AR-15 patterns.
