5 of 5 PWS 6ARC Upper October 28, 2025
Reviewer: David Graham from Mount Sterling, KY  
Very flat shooting, great fit and finish. Looking forward to breaking in the barrel to see how she shoots.

5 of 5 As is expected from PWS... it's great! October 9, 2025
Reviewer: C. Ray from CA, USA  
Although PWS products are great and I have never had an issue with any of their products (they are my go-to), my review will be focused on Mike & Fortress Tactical. Mike is absolutely awesome!!! My first purchase from him was way back in 2017, and will continue to do so as long as I can. He goes above and beyond, and will take the time to answer calls and respond to texts to make sure all your questions and orders are taken care of. You cannot go wrong with Fortress Tactical. Thanks Mike!

Reviewer: Steven Olguin from Weatherford, TX  
This is the 6th or 7th rifle/upper that I have purchased from Fortress, and they deliver every time. Will continue to buy from Fortress.
