Great May 6, 2016
Reviewer: Walt Bryan from Houston, TX United States  
First off my upper was completed three weeks early. Took it to the range today and had zero issues with Monarch ammo. I had several FTF with Tula but I'm blaming the ammo since I tried both types in all my ASC mags, its the ammo not the upper or mags.

I really can't say enough good things about Radicals customer service. I'm fortunate enough to live close to their shop and love going in there. The staff is friendly and straight forward. I've had pistol night sight, gunsmithing, lower engraving, FFL transfers and cerakoting done thru them. These guy actually care about their customers and reputation.
