I have a slightly used CMMG conversion kit used to shoot 22lr out of your AR. Asking $100.00 or best offer. Includes carrier, one 25 rd magazine and a dust cover for the carrier. I shot maybe 500 at most rounds through this, then bought an AR in 22lr. I will not sell or ship this to anyone in California, New York, Massachusetts or anywhere else where it is illegal to own high capacity magazines. I will check your location before shipping. If your area has restrictions, please don't attempt to purchase. I will accept USPS money orders, certified bank check or personal check. If paying by personal check, I will hold item until check clears. First I'll take it followed by PM gets it. Thanks for looking.
