Got this product in Monday and I can say is :woot: It is a really nicely machined piece and threaded in with no problem. It has several setting instead of the two on the original plug for more fine adjustment with different ammo, and detents off the edge of the spring pin. Test at the range included some ultra light trap loads up to heavy field loads. All functioned flawlessly!
