I have a Bushmaster 5.56 AR. I have been thinking about getting a M4 stye upper and stock for it. Also thought about the new 6.8 uppers.
Do you need to change anything on the 5.56 lowers for the bigger 6.8 upper?
Also how do DPMS uppers fit bushmaster lowers? I am thinking about DPMS or Bushmasters uppers?
