Derya Adds the TM22 Pump, a $429 Pump-Action .22 LR Rifle in 18- and 20-Inch Barrels

Derya Arms announced the TM22 Pump, a magazine-fed pump-action .22 LR rifle, on November 6 in a release carried by The Shooting Wire. The rifle comes in 18-inch and 20-inch barrel versions at a U.S. MSRP of $429, and the maker’s product page lists the 18-inch model.

Derya Arms, also known as South Derya Corp., has production in Jacksonville, Florida, and Konya, Türkiye. The Pump is the newest manually operated version of its TM22 rimfire family, which began with semi-automatic models and later added a lever-action rifle. Its semi-automatic TM22 Timekeeper, introduced October 27, lists at $249.

The Pump feeds from the same 10-round TM22 box magazines as the rest of the family, and the release says aftermarket 15- and 25-round magazines fit. Its rifled target barrel has a 1:16 right-hand twist and a 1/2x28 threaded muzzle for suppressors and muzzle devices. A top Picatinny rail takes optics, and the front sight is a bead. The stock has an adjustable cheek pad and basepads that set length of pull, the distance from trigger to buttpad, and cheek weld. Derya’s spec table for the 18-inch model gives a matte finish of Parkerized steel and anodized aluminum.

“The Pump takes that same platform and gives it the classic pump-action experience shooters already know,” said Dustin Jones, Vice President of Derya Arms. The box holds two 10-round magazines, an Allen key and a Derya bag with the user manual. Derya lists both barrel lengths as California-, Maryland- and Massachusetts-compliant, and the 18-inch model’s spec table says the same.

The TM22 Pump is available now through Derya’s authorized dealer network nationwide, according to the November 6 release. The maker’s site carried a page for only the 18-inch model as of November 14, and American Rifleman described the Pump and the Timekeeper that day as the two TM22 additions for 2026.
