What parts are interchangable between the 300black out guns and a standard ar aside from the lower.? I think I know but want to be certain before I start gathering parts for another build.

Standard meaning 5.56? All parts would be the same except for the barrel. The .300BLK casing is just a modified 5.56 casing so the bolt, magazine, etc will be unchanged.

Thanks, I though the only difference was the barrel but was having problems finding anything that said exactly that.

Thanks also.  I learn something new everyday.

Even the magazine capacity remains the same.
