You're looking at a .22 Magnum carbine that holds 30 rounds in each of its two flush fit magazines. That's a lot of firepower for a 3.8lb, semi-auto, collapsible truck gun. It comes out of the box as you see it, including Magpul sights and ambidextrous, non-reciprocating dual operating handles. She's a straight blow-back tack driver that delivers a ton of fun. With the multi-position stock collapsed, the CMR30 is only 22.7a ^2 in length from muzzle to buttstock, making it easily portable and quick into action if needed. The stock positions also enable you to adjust the length of pull to suit your preference. 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 30 rounds of .22 Magnum from a single magazine and 16a ^2 barrel. The best part about that, it comes with two of them. Magazines. Not barrels.
