After building up a sweet Rem 700 (.308) I moved onto one AR15 (then a second AR15 for my daughter). I love playing with my mouse guns, but I really missed shooting my .308. I compromised and moved on to 308 AR as a happy medium. I tell you I thought it would be cake (similar to building up AR15's), but I was slightly mistaken. I'm a student all over again, but that's what projects are for.
