Here are the evil features defined (again):

 

i. A semi-automatic rifle that has the ability to accept a detachable magazine and has at least two of the following:

 

(1) A folding or telescoping stock;

 

(2) A pistol grip that protrudes conspicuously beneath the action of the weapon;

 

(3) A bayonet mount;

 

(4) A flash suppressor or threaded barrel designed to accommodate a flash suppressor; and

 

(5) A grenade launcher

 

So, just to clarify, since there seems to be at least some degree of confusion or debate in past threads on this subject:

 

Say you had an AR, originally manufactured with a threaded barrel, but you had either the manufacturer or an FFL "permanently attach" a brake, or compensator, or thread protector... your threaded barrel is, in effect, not a threaded barrel, and this wouldn't count as having evil feature #4 above.... correct?

correct

Correct. As long as the muzzle device isn't a "flash hider" and is permanently attached.

That is what I thought - Thanks as always!
