    Form 1 asks a weapon description. I'd like to apply to (detachable) shoulder stock a 10 inch Ruger MK2. Once application was approved and the "new" gun created, could I later legally make a change to the gun like threading the muzzle, installing an aftermarket trigger, change grips, etc. without notifying the ATF of the change? What about modifying the stock if I wanted? How does this work? Also, could I be charged with "constructive intent" if I own another MK2 because it is possible that a different barrel/receiver assembly possibly could be made to fit the detachable stock-fitted grip frame? As you may remember, the barrel/receiver assembly on the MK2 is the serial numbered part. These are possibly complicating issues that will affect my decision to go any farther with application process, or drop the whole idea and buy a Buckmark rifle. Thanks, Don.

    I see no reason to notify ATF in the event of the addition to a flash hider/threading or changing of trigger components or grips.

    Constructive intent/Constructive possession typically applies to owning a one SBR AR15 lower and 5 under 16" uppers.

    If you keep things seperate, I would not imagine there to be a problem but if you want to double check me call FTB and ask them.

    You can be charged with "constructive intent" if you are an average man with an average set of tools in the garage and own pretty much any firearm.

    "Constructive intent" is the great internet forum bugaboo. . .

    You would register the pistol as a Short Barrel Rifle on an ATF Form 1. That will allow you to have a shoulder stock attached. It does not mean the stock has to stay on it at all times. The only changes that you would have to report to ATF would be any change that would put the gun in a different NFA catgagory. ATF doesn't care whether or not a barrel is threaded or what type of trigger or grips it has.

    Fixed a couple of things. Not saying that they couldn't try to go after somebody who has multiple AR's and more SB uppers than registered lowers- but that is not the norm. Consider the outcome of TC.

    As long as there is a legal configuration for everything you should be good. The 2nd MKII is a complete pistol. Why would you put a stock on it with the other registered? Like an SBR AR lower, 2 short uppers and one complete 16" AR. Everything has a legal configuration, you wouldn't put a short upper on the non-registered lower with the 16" upper. If you just had short uppers and 2 lowers, 1 registered, 1 not...that's trouble.

    Just my common sense (probably meaningless to the ATF) interpretation.

    Alterations which do not affect any of the fields on the form are okay; trigger jobs, grips, etc. For things which do change stuff that's written down (barrel length, overall length, etc.), you just have to notify the ATF of the change in writing if it's permanent. For non-permanent changes (like stock on/off), you only need to have all the parts on hand to restore the gun to the as-written configuration. So for instance, you wouldn't need to register the pistol with two overall lengths, as long as the stock is easily removable/installable. Just need one overall length, as long as you can readily restore the firearm to that particular length (but there's no reason not to include multiple lengths, just in case).

    The ATF no longer accepts forms that say "multiple" or anything on them, but they do accept ones that say "see attached sheet," and then the extra paper says something like "barrel length: 1", 2", 3", 4", 5"," etc., plus an entire library worth of calibers.
