Deaf Smith seems to have the best common sense and reasonable answer on this. And I think most people would easily let it go at this. It seems unreasonable that anyone in law enforcement or the ATF would come to you looking for problems unless you were blatantly in violation of the law (IE: rifle configuration with a <16" barrel). But, the above post completely contradicts Ranger's original post of 3 ATF agents. Like always, if they want to pinch you for something bad enough, you'll get busted. Doesnt appear anyone in Law Enforcement will ever agree on this hypothetical question. Let's just hope none of us ever have to defend ourselves over it.
