You're looking at a 3.8lb, semi-auto, collapsible truck gun in .22 Magnum. This is a straight blow-back tack driver that delivers a ton of fun. There are many roles the CMR30 can fill. It comes standard with Picatinny-style rails built into its aluminum chassis and the barrel is threaded 1/2 - 28 for your choice of muzzle device. We should probably mention that the trigger has a very nice 5lb pound break and most of this carbine has ambidextrous features. Despite its compact size and minimal weight, the CMR30 dispenses .22 Magnum from a 16" barrel.
