Squat Squad, here’s one for the rimfire crowd. Derya Arms just announced the TM22 Timekeeper, a semi-auto .22 LR rifle built on its existing TM22 action, but with the stuff most people bolt onto a cheap .22 later already on the gun: a push-button adjustable stock with a cheek riser, an 18-inch threaded, suppressor-ready barrel, a full-length rear Picatinny rail, and an upgraded sight setup. Derya says it’s shipping now through its authorized dealer network.
Quick note: this is a release announcement built from Derya’s press release and its own product page. We haven’t had a Timekeeper on the range, so nothing below is a hands-on impression.
TL;DR
- What it is: a semi-automatic .22 LR rifle, the “full package” version of Derya’s TM22.
- Barrel: 18 inches, threaded 1/2×28, 1:16 right-hand twist (per Derya’s product page).
- Stock: push-button adjustable for length of pull, with basepad adjustment and a cheek riser.
- Sights and rails: removable ramped high-visibility front sight, rail-mounted rear sight, full-length rear Picatinny rail for optics, plus a bottom front rail.
- Weight and size: about 4.85 lb, 36″ overall length.
- In the box: two 10-round magazines, tool kit, owner’s manual and warranty card.
- Availability: shipping now through Derya dealers.
Who is Derya, again?
If the name is new to you, Derya Arms (South Derya Corp.) is a Turkish-American manufacturer with production in Konya, Türkiye and Jacksonville, Florida. The company dates back to 1998, and according to the release it only started selling directly to U.S. consumers in January 2025. Its American lineup already covers the DY9 and DY9Z pistols, the RAN and RANX lever guns, a bunch of shotguns (DY12, Derya MAX, the EX imports), and a whole family of TM22 rimfires: Standard, Feather, Flash, Metal and Lever. The Timekeeper slots in as the most feature-loaded of the polymer TM22s.
What makes the Timekeeper different from a regular TM22
Derya’s VP Dustin Jones put it pretty plainly in the release: “The TM22 has always been the underdog that punches above its weight. The Timekeeper is the full package version.” In practice that means three things.
1. A stock you can actually fit to yourself
The standard TM22 gets a basic buttstock. The Timekeeper gets a push-button adjustable stock with an adjustable basepad and a cheek riser. That matters more than people think on a .22. If you’re putting a scope on it, a cheek riser is the difference between a solid cheek weld and doing the chin-floating thing behind the glass. And if this is a rifle that gets shared between an adult and a kid, adjustable length of pull is a big deal.
2. An 18″ threaded barrel, ready for a can
The barrel is 18 inches long, threaded 1/2×28 (the standard rimfire thread pitch, so most .22 cans will spin right on), with a 1:16 RH twist. A suppressed .22 is honestly one of the most fun things you can do at a range, and it’s nice to see the threads come standard instead of as a “maybe on the next model.”
3. Better sights out of the box, and a rail for glass
Derya is leaning hard on the sight package. You get a high-visibility ramped front sight (removable, per the spec sheet) paired with a rail-mounted rear sight, and the company says that’s faster and more precise than the fixed irons on most entry-level .22s. Behind it is a full-length rear Picatinny rail, so when you’re ready for a red dot or a rimfire scope, there’s room. There’s also a small top rail up front with the front sight and a bottom front rail with an integrated stock piece for extra grip or accessory mounting.

Colors and state compliance: read the fine print
Two things don’t line up perfectly between Derya’s press release and its product page, so I’ll give you both.
- Colors: the release says the Timekeeper comes in Grey, FDE and ODG polymer with black anodized metal. The product page spec sheet currently lists the finish as black anodized with black polymer. My guess is the page just hasn’t caught up with every color, but check with your dealer for what’s actually on the shelf.
- Compliance: the release calls the Timekeeper California-, Maryland- and Massachusetts-compliant. The product page spec sheet, as of today, marks it MD compliant: Yes and CA and MA compliant: No. If you live in California or Massachusetts, confirm with Derya or your FFL before you get your heart set on one. That’s especially true in Commie-fornia, where “compliant” usually means a specific variant.
Who it’s for
- New shooters and families. Adjustable length of pull plus real sights means one rifle can fit more people, and a .22 is still the best way to teach fundamentals.
- Suppressor owners. A threaded 18″ .22 is about the easiest host you can find for a rimfire can.
- Budget plinkers who hate upgrade lists. If you’d normally buy a basic .22 and then go hunting for a stock, sights and a thread adapter, the Timekeeper is pitched at you.
- Small-game hunters. Derya specifically calls out small-game hunting, and at under 5 lb it should carry easily.

Our take
The Timekeeper is a smart move for Derya. The cheap .22 market is crowded, and the easiest way to stand out is to ship the rifle the way people end up building it anyway: adjustable stock, threaded barrel, usable sights, and a rail for optics. On paper that’s a lot of rifle for a plinker. What we can’t tell you yet is how the TM22 action runs over a few bricks of bulk ammo, how good that adjustable stock feels when you actually lock it down, and how well the rear rail holds zero. Also, sort out that compliance mismatch before you buy if you live in CA or MA. Until we shoot one, treat the spec sheet as Derya’s claims, but the concept is exactly what a beginner-friendly .22 should be.
