View Full Version : Would this meet the requirement of a 16" barrel?

So I'm currently building an integrally suppressed 9mm AR in my mind (cheaper that way ... and less paperwork).

I really want to build something like this (http://www.coastalgun.com/Home/Suppressors/AR159mmSuppressedUpper.aspx):

http://www.coastalgun.com/Portals/0/Pictures/9mmAR_upperMIMS_1.jpg

Now the problem is, it looks to me like it would require 2 tax stamps (one for the SBR, one for the suppressor).

So could one get around the stamp for the SBR if they were to take a long rifle length free float tube (like this one (http://www.jprifles.com/buy.php?item=JPHG-6M) or this one (https://danieldefense.com/rail-systems/ar15-lite-railtm-14-0-rifle-extended.html)) and put that together with a threaded pistol length barrel? I guess one could just weld the suppressor to the barrel and thus make it 16"+ but I'd like to be able to unscrew the can for both maintenance and to use on other guns.

I'm thinking if SIG can get away with the MPX-C (http://www.sigsauer.com/CatalogProductDetails/sig-mpx-c.aspx) that my idea should also work.

I don't think so. The reg says "barrel" and the tube isn't part of the barrel.

If you were to go to all the trouble to spend the time and money to get the suppressor, I would just pony up the extra $200 for the SBR and do it right.

You can use an extension to the barrel to make up the length. For your free float handguard to qualify, it would have to be welded to the barrel nut, which would have to be welded to the barrel - so not a good idea.

I went the fake route to get a similar look. 16" barrel with a slip over fake can.

If the suppressor was permanently attached to the barrel (silver solder), the entire length would count as the barrel length. If it is over 16", you would not need an SBR stamp. Many people would do this in WA, which used to allow possession of suppressors but not SBRs.

Could they still disassemble them for maintenance?

Depends on the suppressor. Most of the ones I saw were for rifle cans, which aren't serviceable. A lot of the pistol caliber AAC cans have a front end cap, but also the rear endcap unscrews to put a different adapter on and would probably not count as permanently attached unless you soldered that too.

If the threads and rear cap were soldered on my jailbroken ECO9, I could probably get the baffles out the front. Wouldn't be fun but I could do it.

You might spend more money on finding the right can and having it attached than the SBR stamp costs.

That's because OAL is 16".

2 stamps. do it together so you're not waiting 2x as long for what you really wanted in the first place.

Correct if bbl is not pinned extended to a 16" OAL you need it on a SBR or pistol lower. However Having the suppressor pinned or not there is still a need for a stamp on it. I believe we are agreeing but communicating it differently.
However as anyone with a suppressor can verify. The ability to move between host is better then it permanently attached to 1 host.

Stalking Rhino Ind has an integrated barrel suppressor for 9mm if I recall. It would be user serviceable too. What you want can be done. I'm not sure I would do it with a regular pistol can. Get a hold of Matt at Stalking Rino. 919 499 6280. At the very least look into an integrated barrel suppressor

The idea of trying to keep it to 1 stamp is in part a matter of principal and not just expense (hell I don't like the idea of being required to get any stamp but law's law). But also being able to build it in stages would be a good idea too (spread the expense over time 'cause I'm not a wealthy man).

In thinking about all this, I think the way to do it is to build an AR pistol, then register and add the can, then register it as an SBR to add a stock (if necessary ... some folk say the foam pad on the tube is enough ... I would think you'd still get better performance with an actual stock though).

I would agree with these guys. If you are going to get into the NFA stuff just do it right the first time. My 9mm can gets pretty dirty, I wouldnt want to not be able to clean it.

You have 1 extra step. Do the pistol, then buy a can (1 stamp) Then when funds allow SBR the lower (2nd stamp) Then add any stock you want. Or are you referencing the can as first "registered" NFA item?

My plan for the future is to start with an SBR and then add the can when funds allow.

I was referring to the can as the first NFA item, a clearer way to say it would be "then register the can and add it to the gun".

Ah Ha. Do the can 1st. Still suggest you don't make it a permanent fixture. especially once you start shooting with it. You will wish you kept it "mobile". There's another guy who post here (very infrequently) who dcid something similar. Told him he's never going to be happy with 1 can. Get a call yesterday..............."I maxed the CC with 2 more suppressors"
IF at all possible save a few more dollars and send in both applications the same time. For me the NFA game is never ending, sent 3 more in march
