Top teir will only run these exclusively now!!!
What a great company cannot say enough good stuff put in a couple orders. First order the pin and set screw that retains the base plate to the magazine was missing on one of the five base plates that I bought contacted customer service. They immediately addressed it and got the issue. Taken care of immediately ordered five more and I'm about to order five or 10 more not only do they look great but they function great, and are a nice solid addition to any build
