PWS ARs are the best

by JT, Verified Owner from TX, United States Written on September 14, 2017
This is my 5th PWS upper and I absolutely love it. They are the best AR's for the money hands down. Love the piston system for suppressing and all have been extremely accurate. I pair them with the mod 2 lower and they are fairly light as well. I've also had a great experience dealing with PWS customer service. They are awesome and very helpful. Just all around great product and excellent company.
Pros:
  • Reliable, accurate, well made, good looking
Cons:
  • None
Best Used for:
  • Sub 500 yards
