Derya Adds Adjustable Semi-Auto and Pump-Action to TM22 Rimfire Line

Derya is rounding out its TM22 rimfire lineup for 2026 with two new .22 LR models: an upgraded semi-auto called the Timekeeper and the brand's first pump-action rifle, the TM22 Pump.

Snapshot

According to American Rifleman, Derya is building on its TM22 family — which already spans semi-auto, lever-action and other configurations — with a refined semi-automatic model and a new pump gun. Both share the TM22's magazine system and threaded barrels, but target different shooters with distinct furniture, finishes and price points.

Key points

• Timekeeper upgrades: Built on the TM22 Standard, it gets a skeletonized stock with toolless length-of-pull and cheekpiece adjustment, M-Lok slots, QD sling sockets and a fully-adjustable fiber-optic rear sight, priced at $249.
• Pump-action debut: The TM22 Pump brings a classic manually-operated action to the lineup, with polymer furniture, parkerized steel and anodized aluminum parts, priced at $429.
• Shared hardware: Both rifles run 18-inch barrels threaded 1/2x28 TPI for suppressor use and feed from the same TM22 magazines in 10, 15 and 25-round capacities.
• Weight and sights: Each model weighs 4.85 pounds and uses a Picatinny-rail-mounted front post and rear sight with fiber-optic inserts for fast target acquisition.

Quick take

For rimfire shooters, this expansion is worth watching mainly for the operating-system variety: a more adjustable semi-auto plus a genuine pump option in a market segment that's thin on new pump guns. American Rifleman frames the launch as a sign Derya is committed to developing the TM22 platform rather than resting on its original semi-auto design.
