Derya Adds Adjustable Timekeeper and Pump-Action to TM22 Rimfire Line

Derya is adding two new rimfire rifles to its TM22 lineup for 2026, an upgraded semi-auto called the Timekeeper and the brand's first pump-action .22 LR, both built on the existing TM22 magazine and receiver platform.

Snapshot

American Rifleman reports Derya is growing its Turkish-built TM22 rimfire family beyond its original semi-auto roots, which already include lever-action and large-format pistol variants. The Timekeeper refines the base TM22 Standard with adjustable furniture and better sights, while the TM22 Pump brings a classic manual operating system back into the .22 LR market.

Key points

• Timekeeper upgrades: Built on the TM22 Standard, it gets a skeletonized stock with toolless length-of-pull and cheekpiece adjustment, QD sling points and M-Lok slots, plus a fully adjustable rear sight with fiber-optic inserts.
• Timekeeper specs: An 18-inch barrel threaded 1/2x28 TPI, stock colors in black, gray, FDE and OD green, a weight of 4.85 pounds, and an MSRP of $249, with two 10-round magazines included.
• Pump-action newcomer: The TM22 Pump brings a manually-cycled slide action to the lineup, feeding from the same 10-, 15- and 25-round magazines as other TM22 models.
• Pump specs: Polymer furniture, parkerized steel, anodized aluminum, an 18-inch 1/2x28 TPI threaded barrel, a fiber-optic front post with rear sight on a Picatinny rail, 4.85 pounds, and an MSRP of $429.
• Shared ecosystem: Both rifles tap into the existing TM22 magazine family, keeping accessories and spare mags interchangeable across Derya's growing rimfire catalog.

Quick take

This is a straightforward lineup expansion rather than a reinvention: Derya is giving budget-minded rimfire shooters more operating-system choices without changing the magazine or barrel threading that ties the TM22 family together. For trainers, small-game hunters or anyone building a comfortable truck gun, the Pump's old-school appeal and the Timekeeper's adjustability are worth a look once they hit shelves.
