Compact, lightweight guns like the Kel-Tec CMR-30 Carbine in .22 Magnum holds a special place in my heart. They're just so damn handy. The combination of the CMR-30's centrally balanced design, lightweight construction, and extremely light-felt recoil just feels right.
But guns are more than just subjective measurements of ergonomics or feelings they invoke. So let's take a closer look at the CMR-30 and find out if it lives up to the hype.
Kel-Tec CMR-30 .22 Magnum Carbine
The Kel-Tec CMR30 Carbine is deceptively different from the Kel-Tec PMR-30. While it does share the same magazine, it actually operates via direct blowback instead of a locked-breech. This is presumably because the added weight of the longer barrel would make it impossible for the low recoil .22 Magnum round to cycle properly. Especially since the muzzle of the CMR-30 is threaded to 1/2x28 for muzzle devices including sound suppressors.

Thankfully, the engineers at Kel-Tec are no fools, and they arrived at the simplest solution possible: direct blowback.
And you know what? It works. The CMR-30 runs fantastically with nearly all ammo tested - just stay clear of longer polymer-tipped rounds. Everything else had the carbine running like a sewing machine.
And just like the PMR-30 it shares magazines with, the CMR-30 takes full advantage of the .22 Magnum's lightweight and low recoil. The CMR is built from the same lightweight polymer with steel reinforcements and additional aluminum components. But there's more to this gun than just its method of operation.
