Derya Arms (South Derya Corp.), an international firearms manufacturer with production operations in Jacksonville, Florida, and Konya, Türkiye, today announced the TM22 Pump, a magazine-fed .22 LR pump-action rifle available in 18-inch (TM22.PUMP.18) and 20-inch (TM22.PUMP.20) barrel configurations.
The TM22 Pump brings classic pump-action cycling to the modern TM22 platform. A smooth, positive pump stroke cycles the same reliable 10-round TM22 box magazines used across the family, with full compatibility for aftermarket 15- and 25-round magazines. The rifle features a rifled target barrel with a 1:16" RH twist, threaded 1/2x28 for suppressors and muzzle devices, a top Picatinny rail, and a front bead sight. A classic-styled stock with adjustable cheek pad and basepads lets the shooter set length of pull and cheek weld. Unloaded weight is approximately 4.85 pounds.
"The TM22 has always been the underdog that punches above its weight," said Dustin Jones, Vice President, Derya Arms. "The Pump takes that same platform and gives it the classic pump-action experience shooters already know. You get the magazines you already trust, a threaded barrel ready for a can, and an adjustable stock you can dial in — still light, still simple, and still built to run all day. Pump up the underdog."
The TM22 Pump ships with two 10-round magazines, an Allen key, and a Derya bag containing the user manual and WTTA flyer. USA MSRP is $429. Both the 18-inch and 20-inch models are California-, Maryland-, and Massachusetts-compliant.
The TM22 Pump is available through Derya's authorized dealer network nationwide. Dealer inquiries: existing Derya distributors and derya.us.
