5 of 5 Great upper March 4, 2021
Reviewer: Cole from Greenville, MI  
I've always been a big fan of PWS. I own a MK111 Mod 2 as well. They are all built to exceptional quality. This Mod 1 MK107 is no exception. I prefer the forward assist, so the mod 1 is what I went with on the MK107. I was surprised at how smooth this gun runs for being such a small barrel. The ability to adjust it helps considerably. Mine will mostly always be shot with a suppressor and the adjustable piston system is key for this. I wouldn't hesitate on this upper if that is what you're looking at doing.

5 of 5 PWS Upper February 4, 2021
Reviewer: Clint Caddell from Granbury, TX  
I only recently heard of the Primary Weapons uppers.  But, after having purchased one and testing it at the range, I must say it is the most reliable weapon I own. I will upgrade all of my AR rifles to PWS uppers as they become available.

5 of 5 Superior service and communication January 16, 2021
Reviewer: John Burns from Bettendorf, IA  
This seller is outstanding. He is friendly and communicates quickly. Also, he ships fast. The product is awesome, Which is what I’ve come to expect from PWS. No issues to date after over 200 rounds. I have over 4,000 rounds through my MK111 and MK114. Never a problem. Buy this product here!

5 of 5 Awesome upper July 23, 2020
Reviewer: Customer from Miami, FL  
Upper seems really smooth. Minimal oiling and it was good to go. Can't wait to get it to the range if I could ever find any ammo! Mike was very responsive, and sent the item as soon as it came in from back order.
