Look it up friend, the law is the law. AFTE approves braces for AR pistols. Having a lawful weapon is an affirmative defense.
Common sense is not a criteria for the law or a jury, just the law as written.

Uh, PAR35 could be referring to one’s winding up before an Obama judge and a minority jury. Prosecution holds up a pistol braced AR and the jury gasps at the `illegality’ of it.
Common sense frequently is a victim in the courtroom; ask any divorce lawyer. Perception trumps law.
I looked at one; I put the pistol brace up to my shoulder & the store owner said “Now, that’s illegal”. Maybe he was required to say so.
BATFE is not a friend of liberty in any case.
