This is what is the best thing about a forum everyone, seems to be a expert, the info I have gave was directly from ares armor . There is no one to register the lower with. Yes the build parties where stopped you are still able to purchase a jig and do it yourself with a drill press. You can also purchase a polymar lower ar15 which you can finish at home with a Dremel. So if you felt I had given wrong info sorry. I was commenting on another members info about serial number and registering. This is great info I think that all gun owners need to be aware of.
Maybe this could be a thread in the regular forum and not in the classifieds, since this subject of 80% is changing rapidly, as government takes as many rights away as possible. That is just my opinion! Thanks
