Im thinking of getting a ca compliant m&P 15-22. S&W as of today wont make a threaded barrel for the 10 mag gun. Even though its perfectly legal to have a threaded barrel in CA. Whats going on there????? What makes the gun CA compliant besides the MAG. It would still be CA compliant with a threaded barrel. Seems like apples and oranges to me. Let me ask this question? Will a 25mag fit into a ca compliant m&P15-22??
