RVO's Review of Primary Weapons Systems MK116 MOD1-M 16 inch .223 Wylde Upper Receiver

Used it for my first build. Very satisfied with the small recoil, although does run hot after 3-4 mags and also on the heavier side.
Pros:
  • Accurate, consistent, powerful
Cons:
  • Heavy
  • Hot hands
Best Used for:
  • competative shooting
  • range & target shooting
Would Recommend: Yes
