I've seem some posts where people say they want their upper and lower to come from the same manufacturer because they feel they will get a better fit.
So, how "modular" are AR parts? Or, more to the point, what parts do I need to make sure are from the same manufacturer? i.e. lower and upper, lower and LPK, etc.
Thanks
