Fortress Tactical, Our PWS Store! March 2, 2018
Reviewer: Anthony from Florida, USA  
Wow! Not long ago I purchased a PWS MK107 MOD2 pistol chambered in 223 Wylde, so I had to have this 762x39 upper. I was happy to find it here with a PicMod handguard, now that the PicLok has been released. The PWS long stroke piston system is rock solid! Note: If you can find CProducts mags for your 762x39, they complete the perfect package. They are backordered everywhere, so be patient! I had the pleasure of speaking with Michael Lane of Fortress Tactical LLC the other day, and afterwards went on to purchase the items I needed. Their website is clean and easy to navigate - best of all it full of PWS gear at great prices, and most are in stock ready for purchase! My Items were packed well and shipped fast.

5 stars February 19, 2018
Reviewer: Kimberly Berry from Lake Stevens, WA  
We purchase a lot of ammunition and products online. Your company is fast, courteous and deliver on promise. I was told 4-7 days, and my order was here 2 days later on Valentine's day - which was perfect since it was a gift. I will definitely buy again from your company and recommend to others as well.

Reviewer: Josef Zhovtis from Newcastle, WA  
Very happy with my order! I ordered on a Saturday and received my upper on the following Friday. Mike was great and very easy to work with. Certainly ordering more from FT in the future.
