So I've decided to undertake building an AR-10. I feel as though it would be a solid semi-auto long range weapon which is why I want one. I know the specs I want and certain parts. My biggest question is, what are decent brands to use for parts? Uppers? Lowers? Trigger Assemblies (I want an extrememly light weight trigger)? Barrels? Bolt Assemblies?
Any takers?
