    Great communication and a really good deal. Will definitely make additional purchases in the future as well as refer to others.

    Used this on my m18. Removed the manual safety and it works fine. When the stock is folded it doesn’t stay closed. And with the updated charge handle it won’t latch at all. Other then that so far so good.
