[ARCHIVED THREAD] - R6551 Lower Pin Size

Posted: 12/14/2008 7:10:45 AM EDT

Does anyone know if Colt used a small pin hole on this lower? It looks like a standard A2 style lower. Also, would the upper be large or small hole?

I ask because I just bought a R6551, but haven't picked it up yet. I have been searching the net, but cannot find any real info as to when Colt went to standard size pin holes. Does anyone have a web or print reference that would contain this info?

Thanks!
