So I shoot left handed and I have a theory that if I spend a certain amount on a rifle it has to be lefty. So my question is, is it as simple as buying a stripped stag left hand upper(5.56), left hand bcg(5.56), charging handle, barrel(300 blackout), gas system, flash hider and take it to my favorite gunsmith(bptactical) and have him assemble it? Or does it take a special bolt(obviously it has to be left handed)? I have tried doing research but haven't gotten any good solid answers. Please excuse my ignorance I have a lot to learn yet.

Haters and shit talkers need not respond.

Thanks.
