Off the wall question, i called the NFA/ATF guy, but he said i need one of the specialist's there. Anyone know if its is legal. Say i get a 10" bbl for the ar, and i have a 7" can in stainless. If i mount it and tig weld it i would assume that would be legal? I have a rifle i would like to dedicate to a suppressor and that would do it. It would void the warranty of the can but is it legal. but the overall lenght is legal sooo
 
Re: SBR if suppressor is Tig'd?

instead of welding it on, glue the can on with rock set and don't worry about welding it on. This way if need be, you can still get the can off for a rebarrel job etc.

Welding on a can could cause the can to warp just enough to give you some issues with baffle strikes etc also.

Re: SBR if suppressor is Tig'd?

Does "rock set" qualify as a "permanent attachment" if that is the case I may look into running my 14.5" upper with rock set attached AAC blackout FH (making barrel length 16.25") (for my M4 2000) on a lower other than my SBR registered lower. I would certainly not weld a can onto the barrel. Way too many dissimilar metals and the heat generated with firing will cause you issues. And has been posted alread the chance for a baffle strike goes way up. Are you just trying to save the $200 tax stamp or are you prohibited in PA from having a SBR? My suggestion would be to SBR the lower and not worry about it.
 
Re: SBR if suppressor is Tig'd?

No, rocksett does not qualify as permanent. Tig weld would. I would research all NFA rules in regards to this and please dont take my advice as fact. If you tigweld the can on and the OA barrel lenght is 16" or more than it will be legal per BATFE for it not being an sbr. You will have to pay the 200 tax stamp for the can though.
 
Re: SBR if suppressor is Tig'd?

I wouldn't weld the can for reasons stated by others.

If I just HAD to because I wasn't allowed to have an SBR i would get a thread on can and have it drilled from the side for a pin and weld, if that's what you're meaning. I would NEVER do a circumferential weld to attach the can to the barrel.

Tigwelded or pinned would work as long as it is permanently attached. What about silver soldering?
 
Re: SBR if suppressor is Tig'd?

And, send a letter to the ATF requesting an answer. Use the return letter as proof, in case you ever get questioned.
 
Re: SBR if suppressor is Tig'd?

i talked to the gemtech rep today. They have done it and it is legal. They pinned and welded the pin and that qualifies for permenant, I do know rockset is not legal. the can be tig'd on though and no issues. yes here in pa we can get SBR's. I just have a dedicated rifle i want it on, and this would make the overall length shother than a can do now and would still be legal. Gemtech has done it both ways, they do recomend pinning and welding hte pin though. And it would be on a SS can.


Thanks for the info guys.
 
Re: SBR if suppressor is Tig'd?

Another option to consider is the Really Big Flashhider.

Basically it's a pinned tube on the end of a barrel that makes the bbl 16" and allows for attachment of a thread on suppressor. A buddy of mine had this done and the end result was really cool. Great option for states like mine which don't have SBR's. (Or to get away from paying for another tax stamp or permanent attachment of a can.)

Re: SBR if suppressor is Tig'd?

Why not just spend the extra $200 to SBR a lower and have as many SBR uppers that you can afford?
 
Re: SBR if suppressor is Tig'd?

the OP has an SBR... he wants to be able to use a suppressed upper on any lower... I actually get what he wants, and some dealers/manufacturers do this, they pin a suppressor on a shorty upper to get it a "1 stamp" item... it's fairly easy to take the suppressor off if you want to keep it and sell the rest of the upper, and since the suppressor is the ONLY regulated part, it's vastly easier, and $200+ cheaper than SBRing each lower
 
Re: SBR if suppressor is Tig'd?

another option is to TIG a "shroud" on the bbl that covers enough of the suppressor to make the OAL of the bbl 16"... then the suppressor screws in... easier to take the suppressor off... harder to "build"... but very little harder to build

</div></div>That's better than pinning and possibly damaging the suppressor, and it accomplishes the same OAL.
I assume it's intended for 1.5" OD suppressors in 5.56, because they mention 1/2x28, then another 5/8x24 on the barrel for the shroud to be threaded on and pinned.
 
Re: SBR if suppressor is Tig'd?

For fucks sake, just get the other stamp, you'll expend way more than $200 "figuring it out", dicking with it, and then having to convince every person who sees it that it's legal. Unless you shoot exclusively on private land that last one might prove to be worth the $200 itself. I get all kinds of questions and all my shit has a stamp.
 
Re: SBR if suppressor is Tig'd?

Yeah im pretty sure it would cost damn near if no more than the $200 stamp to get the mods done to avoid paying the stamp to begin with.
 
Re: SBR if suppressor is Tig'd?

what about something like this...

http://www.tacticalsol.com/tshome/wp-content/uploads/2011/08/sbx1.jpg

This is a short barrel with a permanent shroud to avoid the tax stamp. The shroud is large enough to accomodate a .22 can. I realize that this is for .22, but I wouldn't think it would be too difficult to make a shroud that would accomodate a .223 can and weld it onto the barrel.
 
Re: SBR if suppressor is Tig'd?

Guys, Isn't an SBR a AOW(Any other Weapon)? And a $5 Stamp? Like a short barrel Shotgun I used to own when I lived in USofA. Had a 7" Serbu!

No. SBR is $200 stamp
 
Re: SBR if suppressor is Tig'd?

It won't cost but a few bucks to do. Sbr are kits a same price as 16". I just wanted to know if it was considered legal which I found out it is. I'm not looking for a flshhider I know I can buy them. I want an overall legal length with the can on. And don't want to pay to sbr a lower. I have a small machine shop to do it in and do shoot on private land. Gemtech has done a few as well the same way.
 
Re: SBR if suppressor is Tig'd?

So refresh my memory. What was the $5.00 stamp for?

AOW
 
Re: SBR if suppressor is Tig'd?

It's not really a flashhider, just a big tube attached to the end of a barrel to make the overall bbl length legal. It's inner diameter is big enough for most standard suppressors to fit inside and the original muzzle thread is left exposed.

Doesn't anyone actually read anymore? Sheesh...
