[ARCHIVED THREAD] - New build ?????

Posted: 3/19/2007 4:21:14 PM EDT

I have a Armalite AR10A4 I am thinking that it would be nice to have an upper in 338 Federal.
Would it work and what would need to be changed. I know the bbl would have to be changed but... Re: buffer, springs etc. If it could even be done.
