For Sale: Never opened Colt AR-15 .22LR Conversion Kit! Comes with Bolt/Bolt Carrier Combo, 10 rd. Magazine, and Barrel Plug. The Conversion Unit is quickly and easily installed on any .223 AR-15 rifle. This allows you to accurately fire the less expensive .22LR rimfire ammunition. To use this kit, you simply take out the standard bolt/carrier combo, replace it with the included bolt/carrier combo, and reassemble the rifle. Then all you have to do is use the included magazine loaded with .22LR rounds. There is no modification of your rifle necessary, and it is just as easy to return your rifle to firing .223 ammunition. The package is in very good shape, and the package has the name and logo of Colt Industries, Inc. on it, as well as the name Colt and Hartford, Conn. USA on the bolt/carrier combo. The price is $200 plus shipping (est. $5) which I think is fair considering the package has never been opened.
