I tried to use the new NFPJ breech plug and bolt insert from a friends extreme. It did not work. The insert that slides into the bolt was to wide to fit into the barrel where the breech plug sits. It just would not travel far enough forward for the bolt to lock into firing position.
I was going to order one but I guess I cant!! Maybe Ill give knight a call and see what they say.
