Keltec CMR-30 .22 WMR 16″ 30-Round Tan

The Keltec CMR-30 .22 WMR 16” 30-Round Tan is a semi-automatic carbine that turns the .22 Winchester Magnum rimfire into a legitimate 100-yard precision tool. Built around a 16-inch, 1:14 twist barrel with 1/2-28 threading, this platform delivers 30-round capacity from a detachable magazine in a compact, collapsible stock. The tan polymer furniture and black metal finish give it a low-visibility profile, while ambidextrous controls and flip-adjustable sights let you run it lefty or righty without swapping parts. Per Keltec specs, the multi-position stock adjusts length of pull from 10.5 to 13.5 inches, making it fit shooters from 5’2″ to 6’4″.

Key Features

• 16-inch Threaded Barrel (1/2-28) – Why it matters: lets you mount a suppressor or compensator without a gunsmith, and the 1:14 twist stabilizes 30-40 grain .22 WMR bullets out to 150 yards with acceptable accuracy.
• 30-Round Detachable Magazine – Why it matters: double-stack design gives you 30 rounds of rimfire before you have to reload, which matters when you’re burning through ammo on steel plates at 50-100 yards.
• Multi-Position Collapsible Stock – Why it matters: adjust length of pull from 10.5 to 13.5 inches for a custom fit, and collapse it down to 26 inches overall for storage in a backpack or vehicle.
• Ambidextrous Controls – Why it matters: the safety selector, magazine release, and charging handle work from either side, so left-handed shooters don’t have to adapt to right-handed ergonomics.
• Integrated Picatinny Rails – Why it matters: top rail at receiver and forend lets you mount optics, red dots, or a magnifier without proprietary adapters, and the bottom rail accepts a vertical grip or bipod.

Who It’s For

This carbine is for the long-range shooter who wants a rimfire trainer that mimics the weight and feel of a centerfire AR without the cost. It’s also for the plinker who needs 30 rounds of .22 WMR on tap for varmint control or steel challenge matches. If you’re a left-handed shooter looking for an ambidextrous platform that doesn’t require aftermarket parts, this fits.

Pros & Cons

• Pro: 30-round capacity is rare for .22 WMR – most rimfire mags top out at 10-15 rounds. You get more trigger time between reloads.
• Pro: Threaded barrel is standard, not an add-on. Save $50-80 on gunsmithing for a suppressor host.
• Pro: Collapsible stock makes it packable – 26 inches collapsed fits in a 26-inch case or duffel.
• Con: The polymer stock has a bit of flex under heavy bipod load – you’ll want a free-float forend if you’re chasing sub-MOA groups at 100 yards. The OEM setup is fine for 2-3 MOA plinking but not precision benchrest.

FAQ

Is the barrel threaded for a suppressor?

Yes, the 16-inch barrel is threaded 1/2-28, which is the standard thread pitch for .22 caliber suppressors like the SilencerCo Sparrow or Dead Air Mask. No adapter needed.

What aftermarket triggers fit the CMR-30?

The CMR-30 uses a proprietary trigger pack, not AR-15 compatible. Drop-in triggers from Timney or Geissele do not fit. You can polish the OEM sear surfaces or send the pack to a gunsmith for a trigger job, but there’s no direct replacement. Per Keltec specs, the factory trigger breaks at 5.5-6.5 lbs.

Can I use .22 LR in this carbine?

No. The CMR-30 is chambered exclusively for .22 Winchester Magnum (.22 WMR). .22 LR cases are shorter and won’t feed properly. Using .22 LR can cause failure to extract and potentially damage the chamber.

What optics mount without a riser?

The top Picatinny rail at the receiver is 0.25 inches lower than an AR-15 flat-top. You’ll need a 0.5-inch riser for most red dots to get a proper cheek weld. For magnified optics, a 1-inch riser is typical.
