I have a used 22lr conversion kit for an AR-15 style rifle. I've personally fired about 200 rounds through it with no issues at all. Bought it because I thought my girlfriend would like it better than the other rifles but she decided she doesn't like shooting rifles as much as handguns! Includes the 25 round magazine and the original packaging. These are about $200 new, I bought mine used for $160 and I'm asking $100 today. OR I can include about 300 rounds of Remington 22lr for $130. Pictures available on request, please meet near Beaverton, St Johns, or PDX.
