Hey guys, I'm considering buying a suppressor for my AR15 from a small local manufacturer. When I do this I'm gonna want to convert my 16" carbine upper to SBR, 9" or 10" (thoughts?). Can I just buy the barrel, tube, and block, apply for the stamp, and assemble it when the stamp comes back? Any good reasons to convert to piston drive while I've got it apart? Thanks in advance.

I do think bruchi did one and it was Ok. My thought would be to get an original manufactured pistol upper in any length you want for the SBR. They can be ordered through the mail from just about any manufacturer like Model 1, Delton and RRA. I have a 10.5 and I had a 7.5 and both worked flawlessly. I would also get a can that could be mounted on either and then you have some great options.
NOTE: If you order the pistol upper and do not have a pistol lower at home the ATF gets REALLY twitchy because now you have ALL the parts to easily make an unregistered SBR at home. So if you go this route get the lower registered as an SBR BEFORE you get the short upper or even better get an AR pistol and your rifle lower registered and now you have a GREAT Leggo set of AR parts to play with.

i had my 9mm AR SBRed, so im not sure about all of the gas stuff. but i had my shorted to approx 10.5" and that puts it just about the front of the FS on the standard M4 setup.
just a note. you want to have the stamp in hand before you buy the parts. it could be considered "intent" if you dont have the stamp first.
afa the piston conversion i will let others more knowledgeable add that info. (imo, just another part of a toy to buy - if you want it, buy it) but i will add that shortening your bbl shorter than the where the gas port is may cause some issues (function?), at least im thinking it could. also, if you shorten the bbl too much, are you willing to live with the any loss in accuracry?

I have a 10.5" PISTOL and it's been reliable so far. I don't see how putting it on a lower with a buttstock would change that.
I'll second the sentiment, "Don't buy a pistol length UPPER without either having a "pistol" lower for it, or having your SBR stamp in hand".
the JBT's from BATFE can get REALLY twitchy about it and can try to lock you up for the next 10 years or so
You will also need a Trust and will have to engrave the receiver with the name of the trust.

Just out of curiosity, how do we know this? Speculation? Proven fact?
I'd like to know, if possible.

I've got three suppressors and don't have a trust. Got the SN on the can, and that's all, along with the MFG.

If I do a trust, do I have to set it up BEFORE I purchase any NFA stamps?
I think I will go with the purchase of an AR pistol.
Yes you will need to have it before you apply for the stamps. the name of the trust has to be on the application along with the S/N of the can and another application for the SBR with the S/N of the rifle.
It is a lot of cash to put out before you ever get to touch your can and then you wait 6-9 months for approval. I have been waiting since mid October (when they cashed my check at the BATF) for 4 cans I bought, not expecting the stamps until April.

Yes because the Trust is the entity that owns the NFA firearm so it is essential it is already in place for you to fill out the application. Go ahead and buy the pistol but make sure you do not put the short pistol upper on the rifle lower until AFTER your rifle lower is already approved and you have your application back with the tax stamp affixed from the ATF.

I would take heed to what these guys are saying. However, if you see a good deal on a short upper and are afraid it won't be around later with this current frenzy going on, give the money to a friend that doesn't have an AR and let him buy it. A upper isn't a firearm, so it is perfectly legal, and your buddy only has a pistol upper, which by itself won't raise any flags.

Actually it should be Ok to buy it yourself as long as you don't keep it at home with the rifle lower. Drop it off at a buddy's house, mom, or anyone you trust.

You can't buy a gun using someone else's money. I guess I don't understand the Trust thing. Isn't that a lot of trouble for almost no benefit?

An upper is NOT a gun....

Very true. I was thinking about a lower.

No need for anyone to buy that but you, especially since you will be the one registering it as a SBR.
