Was out shopping for a Springfield Armory G.I. .45 when I stumbled over a .22 conversion for an AR 15 new in box for $139.99. I grabbed it as I have been trying to order one from Cheaper Than Dirt for a while but them never have 'em in stock. I have heard alot fo good and more than enough bad things about them, but it seems to fit nicely in the upper reciever and after chambering a bunch of dumy and live rounds, extract and eject nicely. Tomorrow will be the real test as I head to an indoor range. I will post an update!
