I have never in my life had better service from a company, let alone a firearm transaction. I bought several rainbow PVD items which vary greatly in color and asked to swap one out. … More Not only did they agree, but they sent me several pictures of everything they had and let me select the one I liked. Then they sent a text to make sure that I liked it when I got it in person. Who does something like that these days? I will absolutely buy from them again and give the highest recommendation. Besides the great service, their products are top notch and so much better than other places I've bought from online. A++++ -
