Frequently Asked Questions (FAQs)

Q: What’s the difference between Derya-branded and Rock Island Armory-branded TM22 rifles?
A: The only difference is branding; both are made by Derya Arms. Parts from Derya’s website are compatible with both (within reason). For warranty/info: contact Rock Island Armory (RIA, APINTL-Pahrump NV) for RIA-branded rifles, or Derya for Derya-branded ones. Pre-2025 TM22s in the USA were RIA-branded; post-2026 are Derya-branded.

Q: What’s the primary purpose of the TM22 series?
A: Recreational shooting, plinking, and small game hunting. Semi-auto models (Standard, Feather, Metal) are ideal for rapid-fire, while the Lever Action offers a classic experience with modern durability.

Q: Are magazines interchangeable between TM22 models?
A: Yes, all TM22 magazines (10-, 15-, 25-round) are interchangeable across models.

Q: Why doesn’t my magazine work in the TM22 Standard due to no front notch?
A: Newer TM22 magazines have a front notch for secure locking in the Standard’s paddle-style release. Older notchless magazines work with Feather, Metal, and Lever Action but not Standard. New notched magazines are backward compatible. Modify older ones with caution or buy notched versions from Derya retailers.

Q: Can I use aftermarket AR parts with the TM22?
A: Yes, AR-type grips and buffer tube adapters work on all models. Some AR stocks fit semi-autos, but handguards are proprietary.

Q: Where do I get a cheek riser for my TM22 Standard?
A: Available at https://derya.us/tm22-standard-stock-kit/.

Q: What ammo works best with TM22 semi-auto models?
A: High-velocity .22LR (e.g., CCI, Armscor) performs best. Subsonic rounds may cause FTEs, though break-in or suppressors can help.

Q: Is the TM22 threaded for suppressors?
A: Yes, Feather, Metal, and Lever Action have 1/2x28 TPI threading. The Standard does not.

Q: How do the weights compare across models?
A: Feather (4.5-5 lbs), Standard (5 lbs), Metal (6-7 lbs), Lever Action (7 lbs).

Q: How durable are the TM22 models?
A: Metal’s 7075 aluminum build is highly durable. Feather and Standard’s premium polymer stocks are robust. Lever Action’s aluminum construction ensures longevity with care.

Q: Can the TM22 be converted for left-handed use?
A: Lever Action is ambidextrous. Semi-auto models have right-handed controls (left-side charging, right-side mag release).

Q: What’s the trigger like on the TM22?
A: Semi-auto models feature a 2-lb flat-faced trigger with short take-up and quick reset. Lever Action has a typical lever-action trigger.

Q: How do I clean the TM22 semi-auto models?
A: Remove the top Picatinny rail to access internals; re-zero optics afterward if needed.

Q: I have a TM22 Cadet—what’s that?
A: The TM22 Cadet is the Canadian variant. Derya sells to 60+ countries with region-specific names. Contact your Canadian Derya dealer or visit Derya Turkiye’s website for details.
