In your opinon. Until the rule is published and unchanged from what we've seen so far, that may be.... "kind of true". But it hasn't and a brace is still a brace and a pistol with a brace is currently not an SBR.Braces are stocks so when it has a brace on it it will be an SBR. Come back in December and agree with me.
Study this in the mean time.
Look it up! I'll wait. (as you are so fond of saying)
If you really took the time to read, you would realize that the ATF is not exactly trying to reclassify a brace as a "buttstock". What they are doing is saying that... even though it has a brace it may still qualify as an SBR under the new rule. That's a fine line, but even the worksheet distinguishes between "stocks" and "braces".
