Will any dpms style upper work in this lower?
John G on Nov 9, 2018
BEST ANSWER: Yes, DPMS above in the description (Compatible With), however, in my mind it only makes sense to purchase this matched set, if you are going to use the upper that is part of the set (buy a barrel, hand guard, UPK, tube and block, etc. and put it together.
What is the thread type for the upper receiver in this set for the barrel nut?
