text: I have been researching all the new rules for pistol braces. From all I have found you will have until Dec 31 to either destroy the brace or the AR all together or do a form 2 to apply for a SBR tax stamp. Yes it does require a $200.00 fee and will be a pain in the ass. If you have a national firearms trust you can use it. If not then it will require obtaining permission from your county sherif along with passport photos and finger prints to be submitted. There is another way. Replace the upper with a 16" barrel then destroy the short barrel. If you destroy the brace or upper you must be able to show proof. Apparently this does cover all weapons with a brace having a barrel length under 16" This could change but for now these are the new regulations. I am not inanyway telling people what to do just passing on the info I have found while researching and consulting a lawyer. Hope this info helps.
