5 of 5 PWS MK1 MOD2 Lower/Fortress Tactical Saturday, September 12, 2026
Reviewer: Keala from Wernersville, PA  
Had my reservations about a company/retailer I've never heard of that also has good prices. Mike definitely put me at ease, mentioning the positive reviews. He even texted me about my order status, and how my FFL hadn't responded to his emails. I got the lowers and they were what I expected. PWS makes my favorite ambi lower. I won't hesitate to order here again, and neither should anyone reading this.

5 of 5 Amazing service and communication Monday, March 9, 2026
Reviewer: Evan from WI, USA  
First off, great communication and super fast shipping to my FFL by Mike. I had an e-mail the next day letting me know it would be in the mail as soon as he heard from my FFL. Responded on a Sunday around noon, item must have been in the mail early Monday as it arrived at my gun shop on Tuesday! Awesome service. The lower speaks for itself though. My first buy from PWS, and I will return for another if I decide to do a new build or drastically improve an old one. This is nicest lower I have ever seen in person. Love the design, perfect fitment, and the ambidextrous controls are a game changer! Well worth the money.

Great lower with the fit, finish and ambi controls exceptional. This was my first time dealing with Fortress Tactical and won't be my last. Great communication from Mike and quick shipping. Great price as well.

5 of 5 Great Experience Wednesday, March 19, 2025
Reviewer: Customer from Fort Worth, TX  
The prices were lower here than anywhere else, and shipping was fast. They reached out when the FFL here was dragging their feet and let me know there was a problem, allowing me to resolve it quickly.  I will buy from them again.
