suppressor dilemma

[green country shooter]

Now I know i am very spoiled, but it's a serious question.

I have a 20" Ar i bought during the Assault Weapons ban, not threaded, no suppressor.

I have a 16" AR i bought with a permanently attached flash suppressor.

I want to buy a suppressor and have spoken to a dealer. The problem is, the 20" will be very long with the suppressor, so i'd prefer to use the shorter gun, which means a second tax stamp, but also: i bought it for cash. No one knows i own it. If I shorten and thread the barrel i will have to give up the serial number.

So my options seem to be:

1. a very long barrel suppressor combo
2. give up the "off the books" nature of the AR
3. buy a new one!

thoughts?

true

No, if you send the shorter upper to be threaded it isn't a firearm so no record of the serial number will be made. The upper doesn't even have a serial number. There is no reason to even take the lower (the serial numbered part) out of the house when you get the barrel threaded.

Second option: buy a new upper. You don't need to buy a whole new gun. You can buy an infinite number of uppers and put them on either of the lowers you already have.

Third option and the one I would take: get everything threaded.

Fourth option: replace either of your barrels with a new barrel. Not hard at all and you don't need a gunsmith to do it. Or, you could send either of your current uppers to a gunsmith and have him install a new, threaded barrrel on the upper.

I have one 20" upper I use with a suppressor. It's long, so what ?
If you decide to go the short barreled rifle route, you can register either or both of your current lowers as SBRs and you are perfectly free to use either of your current uppers or furture uppers on the registered lower. BUT, if you decide to register the lower absolutely you are going to put the serial number of the Form 1. "They are going to know you have it". On the other hand, you can just register the other lower you have as an SBR and use it with either upper.

huh? why would the 16" ar mean another tax stamp? are you implying you'd remove the perm attached flash suppressor?

It's not like your name isn't already out there for other purcahses, no need for the secrecy. On the other hand, to cut, crown and thread the barrel you are going to drop some cash that could be invested into a new 16" AR. Maybe one of these CMMG bargain bins for $599

it's 16 with the flash suppressor. If he removes it to use the sound suppressor, the rifle is now an SBR.

 

[taliv]

or... he could buy a suppressor that QDs onto his existing flash hider so he doens't have to remove it

Yeah that might work, but I have no idea what kind of flash suppressor he is talking about.
I was picturing something like one of those uppers with an 11" barrel and a big flash suppressor.



FWIW: my 5.56 suppressor is an AAC M4-2000. It mounts to a flash suppressor that they sell. It threads right onto a standard USGI/commercial AR15 thread. Personally, I think it is a great mount. When I got the suppressor I just bought as many of their flash suppressors as I had AR15s and just screwed them on. I can now use the suppressor with any of my ARs and if I don't, I still have a highly effective flash suppressor.

Simple...take the 20" to your local smith and have him cut, crown, and thread...purchase a QD type suppressor and the flash hider to go with it and if you are lucky you can use it on both (dependent upon the style of flash suppressor on the 16" bbl).

Ther are options out there as provided by others.
but the bottom line comes to if the barrel is under 16" you need a permit period for a rifle.

I think the cheapest thing to do would be just to buy a new barrel.
The easiest would be to buy a new, complete upper.

How permanently is it attached? Just hard soldered at one point or all the way around? Nothing a little work with a dremel tool can't fix(or a crap ton if its soldered all the way around). This is assuming it was "permanently" attached just for the ban so it wouldn't be able to accept muzzle devices and is of a legal length without it.

If your serious about dropping the cash for a good suppressor and tax, you might as well go short while your at it if that's what you want.
