5 of 5 Excellent Experience June 19, 2020
: Brendan Cromer from Defiance, MO United States  
Shipping was very fast even though there is a lot of holdups in the shipping industry right now. Upper came in perfect condition and was just as the website described. Very high quality build and even the logo on the rail had clean edges. Upper was even less prone to scratching than my Daniel Defense Rail was. Overall I would order again from them easily.
