Is it illegal to put a pre-ban lower with a post-ban upper or what is the differance and also about the barrels with the bayonet lug can that barrel be put on a post-ban lower? How does this work? Confused......hacko.gif

PRE-BAN--Can have all evils, combo of evils or no evils.

POST-BAN--NO EVILS,,,, PERIOD.

The lower is the registered, transferable, serial numbered protion of an AR-15/M-16.

If you have a Pre-Ban lower, the upper may contain all of the bad/evil features or none and still be legal.

If you have a Post-Ban lower, the upper may NEVER contain any of the the bad/evil features.

Barrels lengths of both, for civilian use, must be 16" in length.

The exception to this rule is SBRs, short barreled rifles, which like full-auto/select-fire rifles must be cover with a Federal permit/tax stamp and requires additional paper-work, money and approval.

Rather simplistic explaination, but it will hopefully suffice.

Well.... That was great.... I was just wondering because of the fact that a friend of mine has a pre-ban lower and I have a post-ban upper and we wondered if there was something wrong if we put them together and went to the range.... guess not.... thanks....

The only other caution that should be mentioned is to make sure you can show that the lower was assembled into a complete rifle prior to the ban. Then as Mr_Wilson states you can do about anything thats non-NFA that you want.

Putting a post-ban upper on a pre-ban lower is perfectly legal. (as long as the upper is otherwise legal - e.g. barrel at least 16" in length)

Hey Plinker

Check this out . Coltcarbine's post explains it easiest . At least  for me it did *lol*

Except that Coltcarbine's wrong - he's made the common mistake of thinking it's "2 features"

The actual law reads "semi auto with the ability to accept a detachable magazine, and ONE feature".

A detachable magazine is not an evil feature - it's part of the AW definition.  No detachable mag means the rifle is not subject to the AW ban no matter what.  With the detachable magazine, if it's semi auto, it gets ONE feature - which is usually the pistol grip for an AR type rifle.

If you are willing to permanently attach your magazine and load the rifle through the top of the magwell (break it open, I guess), then you can have a telestock and bayonet lug and flash suppressor and all the other evil features on your post-ban rifle.  Others have done this by disabling the gas system, making the rifle a bolt action - and also no longer subject to the AW ban.
