  1. Vance Payne

    dropped this 9mm Magwell adapter in one of my extra Anderson AR-15 lowers to make a 9mm out of it. Im very impressed with the quality, not cheaply made and works! Used rock river 9mm stick mags. Fast shipping too!

    Great product,well engineered . Sets in the receiver solid,no wiggle at all. I can even use my modified UZI mags. Thanks for a great item at a reasonable price.
