Reviewer: SimonsGotAGun from O'Fallon, MO  
Ordered a PWS upper and lower on Thursday evening, and had them the following Monday. I got an email from Mike within minutes after placing my order asking me about shipping. Would definitely buy here again.

Best in class product & service April 4, 2018
Reviewer: Hootloops from Pflugerville, TX  
I'm very satisfied with the PWS MK109 MOD1-M 9.75 300BLK upper purchased from Fortress Tactical. The customer service from Mike Lane was excellent, and he offers the best pricing on PWS gear or will match a competitor's price. I placed an order on a Thursday night, and it was at my door by noon on Monday! I'll be back soon for a MOD2 lower, and maybe some Bootleg gear for my 5.56 build. Thanks again Mike.
