    Great substitute for non threaded barrel

    Great susbtitute for non threaded barrel. Save a couple of hundred dollars on my ar15-22 was thinking about sending the barrel to get threaded but the cost was almost as much as I paid for the rifle. This was cost effective and the rifle looks great with the plain black shroud.

    This adapter is very will made. It fits very snuggly in my M&P1522. The treads are made very fine so that the surpressor will fit very good. Great product for your M&P1522.

    Adapter fit great, secured well and allowed me to run a barrel shroud giving the rifle a little personality.
