I'm not asking what tools you need to add a stock:D just wondering what forms you have to complete and where I could find these forms.:D

[Telekinesis]

ATF's Form 1 is what you need to build/register your own SBR. It's a $200 tax and about a 6 month wait (and you can't start the build until you have the form back with the tax stamp). You're also required to engrave the receiver.

The Form 1 should be on ATF's website. Remember to print it front and back (one page, not two). I have heard stories about them putting you into problem status if you print it on two pages...

[tepin]

Actually you can start the build as a pistol assuming your lower receiver has never been a rifle. When you get your stamp, slide a stock onto the buffer tube and you are all set.

When you get your stamp, slide a stock onto the buffer tube and you are all set.

Not quite, you have to use a pistol buffer tube on a pistol, and then replace it with a rifle tube and stock after you get the stamp.

[Aaron Baker]

Do you have an ATF ruling on that issue, Wally? I seem to remember that you can use any buffer tube you want. If you don't own the stock that goes on the buffer tube, then you can hardly be accused on being in "constructive possession" either.

If you don't own the stock that goes on the buffer tube, then you can hardly be accused on being in "constructive possession" either

I'm not a Philadelphia gun lawyer, but I guess as long as you don't have any stock that would fit the tube you should be OK. If you could pull one off your AR carbine then there is your "constructive possession" same as if you had a pistol upper and only an AR rifle.

Here are some on-line collections of ATF letters:

http://www.nfatca.org/BATF_Letters.htm

If you are confident you see one that says using a rifle tube on a pistol is OK, by all means go ahead. For the price of a pistol buffer tube its just not worth taking a chance to me. YMMV.

[Aaron Baker]

Well, I'm no fancy lawyer either--just a regular old Kentucky lawyer.

If you follow this link:

http://archery.ar15.com/archive/topic.html?b=3&f=122&t=548417

and scroll down, there's an ATF letter than says you can use any ole buffer tube you want on a pistol build, but that you run the risk of constructive possession if you have a buttstock that can be attached.

Here's a link to just the letter:

So long as I don't have an extra buttstock handy, I wouldn't personally spend the extra money on a pistol buffer tube. And I wouldn't particularly worry about visits from ATF agents checking up on that configuration, since I've never seen an ATF agent in the wild.

In summary: if you're cautious, use a pistol buffer tube. If you're not worried about it, use a carbine buffer tube as long as you don't own the buttstock yet. But you're not legally required to use a pistol buffer tube on a pistol.

Uh.. not always. A pistol .223 AR15 will still run on a carbine buffer and tube. Its firing the same 5.56/223 cartridge, just on a shorter barrel.

ATF Form 1, two copies required, print pages 1 and 2 double-sided:

Certificate of Compliance, one copy required, just print page 1:

My AR pistol is in my bedroom closet and the stock is in a box in my basement waiting for the stamp. I sleep fine at night.

I would like to know if anyone has ever been prosecuted for "constructive possession" that resulted in conviction or acquittal for that matter **AND** the prosecution for constructive possession of a SBR was not related to another crime. In other words, I would be willing to bet that constructive possession occurs when law enforcement (LE) are kicking your door in for some other reason (drugs, gun running, terrorism, etc...) and they look for any others charges to stick you with, hence constructive possession of something. With the common chemicals found in most homes, we are all guilty of constructive possession of explosives. :what:

the issue is not whether the gun will run or not, and its not the buffer that;s the problem legally when you making a pistol. its the tube itself. the difference is that a pistol tube has no way to slide on a collapsible stock, like a regular commercial or military sized tube. the buffer inside the tube has nothing to do with it.

There's a whole other world of SBR candidate rifles out there besides the AR...

As much as I hate to be accused of trying to get back to the OP's original question, here is a link to the forms.

http://www.atf.gov/forms/firearms/

NFA stuff is about halfway down; they are the 5320 series. You will want the 5320.1 to build your own SBR. Note that you have to order the fingerprint cards from the distribution center as they cannot be printed from the website.

http://www.atf.gov/forms/dcof/

You need the "FBI FD-258LE - NFA, Imports ORI WVATF0800" which is at the bottom of the right sidebar. You need two copies, but I usually order more just in case one (or more) gets screwed up. Don't order the wrong ones and don't let the local police tell you that the ones they use for booking are okay, as they are not.

You can also order the hard copy Form 1 there, but I just fill them out online. They can be hand-written but I would hate to have them kicked back (and delayed even longer) because of penmanship.

If you go trust route, no finger printing or CLEO signoff

[sniperlongshot]

i built mine as a pistol first, then when my form one came in i changed out the buffer, since then, possion of all parts constitutes intent to assemble/make.....that's a violation in itself now, if you buy an empty unmade lower, buy it as a pistol receiver on your receipt and keep it with the lower in a hard case, that way if you buy the upper, and have decided on the buffer, you'll know what to put on the form 1 for overall length etc,. but just make sure you get the form 1 before you get all the parts, if you go the pistol receipt, you can build the pistol 1st and play with it untile the form 1 comes in, but if you have your design finished in your head, then just buy the lower and then build it later

You can SBR ANY rifle you want. Some folds do ARs, but some do AKs, bullpups like the PS90 are awesome when you shorten the barrel....others include the UMP clones you can make from an H&K USC, the KRISS Super V is a great SBR - some folks like MP5 clones, UZI rifles - the list goes on and on.
