New to the site and new to the .308 AR platform. I'm not new to AR-15's though. I plan on building a gun soon (hope to have it compeleted before November) and I plan to start with the Mega MA-TEN receiver set. The rifle is being built for play and occasional hunting, but I want to be able reliably shoot out to 1,000+ yards. I know for the lower receiver I can just use AR-15 parts, but what options are there for barrels, handguards, BCG's etc.? Right now I want to concentrate on putting together a rifle that'll run with no issues, and not break the bank. After it's up and running I'll start looking at glass and a can (after the proper paperwork of course).
