all the uppers from PSA come with the A2 flash hiders, wouldnt that make them illegal in nj?
edit:: after looking around and searching
A semi-automatic rifle that has an ability to accept a detachable magazine and has at least two of the following:
This means that if it is a semi-automatic rifle and has a detachable magazine it can have ONE of the following features and still be legal, but if it has two or more, then it would not be legal. 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; 5) A grenade launcher youre good
so if you buy an upper from PSA and weld / pin on a brake or comp youll be fine, if you want the A2 flash hider then you cant have a folding stock, pistol grip, bayonet mount, grenade launcher
