I only gave this place a one star because you can't go any lower. I took an AR upper to
these guys to get a flash hider pin and welded. To make a long story short..Stay away from these idiots they don't know what they're doing..I know more than they do about AR's. They can't tell aDI system from a piston system and that's bad..but top make it worse they don't even offer an apology for screwing up and that my friends is terrible customer service.
