Kel-Tec CMR-30

The Kel-Tec CMR-30 is a semi-automatic carbine chambered in .22 Winchester Magnum Rimfire, designed as the rifle companion to the PMR-30 pistol using the same 30-round double-stack magazine. It features a lightweight polymer construction with a folding stock, an aluminum Picatinny rail for optics, and M-LOK slots on the forend for accessories. The CMR-30's blowback operation is uniquely combined with a delayed unlocking block that prevents out-of-battery firing, allowing reliable cycling with the wide pressure variations found in .22 WMR ammunition. The carbine weighs just 3.8 pounds and folds to a compact 22.5 inches, making it popular for backpacking, ranch carry, and recreational shooting where lightweight and high capacity are priorities.
