Description
The Kel-Tec CMR-30 Carbine — .22 WMR, OD Green is a lightweight, semi-automatic rimfire carbine built for speed, accuracy, and low-recoil shooting. Chambered in .22 Winchester Magnum, this platform delivers flat trajectory and terminal energy well beyond standard .22 LR, making it a serious tool for competition steel, varmint control, and training. OD Green finish keeps it low-profile in the field. At just over 4 lbs, it’s a carbine you’ll actually want to carry all day.

Key Features
- Ambidextrous Controls — Safety selector, charging handle, and magazine release are fully ambi. Why it matters: left-handed shooters don’t lose a beat, and righties get faster transitions in weak-side positions.
- Adjustable Stock — Six-position collapsible stock. Why it matters: dial in length of pull for prone, barricade, or heavy clothing. Keeps your eye aligned with the optic every time.
- Threaded Barrel — Factory-threaded 1/2×28 for suppressors or compensators. Why it matters: run a can to cut noise and flash, or add a brake to tame muzzle rise for faster splits on steel.
- Integrated Picatinny Rails — Full-length top rail and M-LOK slots at 3, 6, and 9 o’clock. Why it matters: mount any red dot, magnifier, or LAM without adapter plates. Zero shift is predictable.
- Detachable 30-Round Magazines — Ships with two translucent polymer mags. Why it matters: fewer reloads in a stage or varmint hunt. See round count at a glance.
Who It’s For
This carbine is for the shooter who wants rimfire economy with magnum punch. If you shoot steel challenge, NRL22, or just hate racking a bolt between strings, the CMR-30 delivers. It’s also a top choice for varmint control on ranches and farms where .22 WMR gives you a 150-yard effective range with minimal meat damage. Light recoil makes it a great trainer for new shooters or anyone recovering from shoulder injury.
Pros & Cons
- Pro: Sub-4.5 lb weight — one of the lightest semi-auto carbines in any centerfire or magnum rimfire class.
- Pro: 30-round capacity in a rimfire carbine means more time shooting, less time reloading.
- Con: .22 WMR ammunition costs more than .22 LR — expect to pay roughly $0.15-0.25 per round vs. $0.05-0.08 for bulk .22 LR. Not a plinking budget round.

FAQ
What is the twist rate of the Kel-Tec CMR-30 barrel?
Per Kel-Tec specs, the CMR-30 uses a 1:16″ twist rate, optimized for the 30-40 grain .22 WMR bullets common in varmint and match loads.
Does the CMR-30 accept aftermarket triggers?
Yes, but options are limited. The CMR-30 uses a proprietary trigger pack. Timney and Geissele do not currently offer a drop-in. Some shooters polish the factory trigger; expect a 5-6 lb pull from the factory.
Can I run a suppressor on the CMR-30?
Yes. The barrel is factory-threaded 1/2×28. Use a .22 WMR-rated suppressor like the SilencerCo Sparrow or Dead Air Mask. Note: .22 WMR is louder than .22 LR suppressed, so ear pro is still recommended.
Is the CMR-30 reliable with all .22 WMR ammunition?
Most high-velocity .22 WMR ammo works well (e.g., CCI Maxi-Mag, Winchester Varmint HE). Some subsonic or low-velocity loads may not cycle the action reliably. Stick to 40-grain or lighter bullets rated over 1,400 fps for best function.
