5 of 5 3rd purchase now August 10, 2021
: Steven Soltysiak from Foristell, MO United States  
I’ve just received my 3rd purchase from you guys in the last 2 months, and could not be happier. Not only with the pricing and quick shipping, but the selection sets you guys apart. Not only can I select the size and  hand guard design, but Also the manufacturer of the exact barrel you will mount on it for me?? Absolutely great guys. With this being said guys, don’t go raising ur prices. This is what sets you apart and has me showing my friends and coworkers. Keep up the good work. Thanks again
