I have heard rumblings that the ATF is considering a re-ruling on the Sig arm brace from my LE friends. Too many people are using it as a stock and shoulder firing pistol ARs and flaunting it on youtube and other media. The ATF does not like when a device they approved is used to circumvent other rules.

They are talking about a modification to the design to require at least 1 inch of the buffer tube to extend past the brace or some other modification that would make it less than comfortable to shoulder fire. A recall would be required and a 1 year grace period will be allowed to allow owners to exchange their braces.

The whole thing is silly any way. What difference does it make how you fire a gun, or how long a barrel is? A better plan would be to scrap the entire NFA.
