Charger bullpup

    OK, here's the scenario:

    I've ordered one of the ZK22 bullpup kits from Red Jacket. Yeah, I know, some people hate them but I think it will be a fun build. They specify on their website that you much use at least an 18.5 inch barrel or it will have to be classified as a SBR. OK, fine. I don't mind applying for the stamp if I decide to go that way. Right now I'm considering a threaded 1:9 twist barrel for the 60 grains and a suppressor.

    After a little research (this site is awesome BTW, you guys really know your stuff) I found that the Charger receiver and the 10 22 receiver are the same except for the stamping and original registration. The Charger receiver is a pistol, the 10 22 receiver is a rifle, and BATFE looks at building one as the other is a big nono.

    So what if I buy a charger and drop it in to the bullpup stock? Short barrel, pistol markings on the receiver, overall length fits below extended pistol parameters. Is it clear without a stamp?

    No, putting it into a stock which is designed to be fired from the shoulder will make it into a SBR and you'll need a stamp.

    No. If you put a charger in that bullpup stock you will have added a stock. You will have made a rifle by doing so. In as much as the resulting rifle would have a barrel shorter than 16" it would be an SBR. It also would be an SBR because it seems it would have an OAL less than 26". You would be well into felony territory.

    Adding a stock to pistols makes them rifles. If they have shorter barrels or shorter OAL they are short barreled rifles and need a stamp.

    Absolutely correct, thank you. From BATFE website:

    What if the bullpup stock was in some way modified to have no provision to fire from the shoulder? Modify it so it's more like a pistol stock that moves the balance much firther rearward?

    About the time I was posting this thread I placed a call to RJF to ask them the same question. Right after I posted the BATFE info here I got a call back from their legal guy and it seems we are all on the same page, so to speak. There was one point he and I agreed on as well, and that is if you find yourself in a gray area as far as a BATFE issue goes, lean toward their side. Much safer that way. I don't think there is a particular standard as far as pull length and how much constitutes a rifle stock, but if you think it might be, it probably is. I'd rather pay the $200 than do the time.

    People have done this with the draco pistols. Personally, I would just pay $200 and be in the clear. Two hundred dollars is not very much money and is very cheap insurance against potential legal issues. At a minimum I would want a letter, addressed to me, from the ATF in a safe place before I proceeded.

    You can build arm pistols like Bushmaster made in the 1980s. They're basically bullpup pistols. Kind of useless though.

    Just a couple of points to throw in the mix:

    1) 16" barrel is not the only thing you need to worry about. To avoid creating an NFA weapon (if you choose not to go that way) any time there's a shoulder stock on the gun you have to keep the overall length above 26" as well. Not sure if that's an issue with this bullpup kit, but keep it in mind.

    2) As of last year, it is now considered legal to build a "Title I" rifle on a receiver that started life as a pistol, and then convert back to a pistol again (as often as you wish). Just keep the assembly steps in the right order so you don't temporarily build an SBR.

    I'm thinking that if you put a 10" barreled charger inside that bullpup stock the muzzle would wind up just before the exposed area above the forward grip. You'd have a bullet sailing through the bullpup stock and just above your hand every time you pulled the trigger. Seems like it wouldn't be the smartest bullpup arrangement...

    No...no point to it as you're just losing barrel length without shortening the OAL.

    Unless you can fit a 'can down inside there! That's when it gets cool, and really does help with the length.

    Seems like an integrally suppressed 18" barrel would save you $200.

    Save $200 because of needing only one stamp for the integrally suppressed barrel?
