most pre bans have the bayonet lug
there was really no reason to remove them pre 1994
a threaded barrel is another preban attribute that is easy to spot
heres the definition:
Any semiautomatic rifle that has the ability to accept a detachable magazine and has at least 2 of the following features:
* a folding or telescoping stock.
* a pistol grip that protrudes conspicuously beneath the action of the weapon.
* a bayonet mount.
* a flash suppressor or a threaded barrel designed to accommodate a flash suppressor.
* a grenade launcher.
