[ARCHIVED THREAD] - AR-10 upper source help?

Posted: 8/2/2009 8:36:09 PM EDT

I'm thinking of buying a CMMG .308 lower and was looking for a good source for uppers. I noticed that DPMS has some but what are some alternatives? I'd like a complete, barreled upper with a 24" (or more) barrel.

Also...

This would be my first .308 AR build. What considerations (ie: divergences from an AR15), if any, should I keep in mind when buidling up the lower?
