Guys sorry for the noob question but I'm working on putting the parts together as I can find them to build my first AR Fankengun! My question is this, I recently found a stripped upper with the forward assist option, I am unsure as to what type of BCG to purchase, do some of them have an orientation for forward assist vs non forward assist?? I have only seen one bolt carrier group that specified either way. I just want to make sure that I don't order the wrong part once I find it!
Thank you guys so much for all your help!
