I have for sale a CMMG .22LR conversion kit (blued) for an AR-15, with an extra 25-rnd magazine. Bought it at Bass Pro Shop a couple of months ago and have never used it. I do not have the original packaging, but I do have the instructions. This is really brand new... I have never even put on my AR!
Bass Pro Shop sells the kit (bolt + 1 mag) for $190 and the extra magazine sells for $26, plus shipping & handling. I'm asking $185, with shipping via priority mail included. Will not ship to CA, NY, CO or where prohibited. Check your local laws. Cash or PayPal.
