Wisco Guy's Review of Primary Weapons Systems MK111 Pro 11.85in Upper Receiver

This PWS upper is everything I expected and more considering it is the lowest price entry for PWS pistol/SBR uppers. The fit and finish is superb and matches well with PWS lowers. More importantly, the long-stroke piston system runs clean and reliably. Very easy to adjust and tune for the perfect gas setting which makes for a pleasant shooting experience. Unfortunately, I haven’t tried it suppressed yet. Accuracy is good at 2-2.5 MOA with Federal American Eagle 55gr. Highly recommend!
Pros:
  • Fit and finish
  • reliability
  • American made
  • Afffordable
Cons:
  • None
Would Recommend: Yes
