Bingo you are 100% correct they simply put the sear in the trigger and shit is going to hit the fan with atf. I am not saying I agree with any of the bullshit gun laws including the NFA but its the law and I already know what is coming down the pipe. It's no different than a john norell trigger pack for a ruger 10/22 or a H&K trigger pack for the H&K firearms. LOL its almost so comical there is not even words.
