Hey rjrivero, you got this thing installed on an upper yet?
ADCO posted pictures of your barrel over on ARFCom.
We'd like to see how the final product looks. (yeah - we're a little impatient).

ROFL. Not quite yet. They built that with the WRONG barrel nut. I'll have the correct one in a few more days.....Originally Posted by GarrettJ
Edit: I just got back from ADCO. We're going to have to make the shroud a smaller diameter to fit under a YHM rail. Right now the tube is 1.75 and the collar they have on it is 1.93 or so. I'll need to talk to the machinist to see if we can fix that so it can be covered by the rail.

Well, we're off and running.Originally Posted by rjrivero
I discussed some of my ideas with ADCO. They've been really receptive to this idea and we got a mock up done.
The tubing I had to provide, it's made of 2024 Aluminum. It will fit under a YHM rail and a standard suppressor fits under the shroud.
The overall length of the barrel plus extension is 16.25" The barrel is threaded twice the normal length. The collar or adapter is threaded to fit the barrel, and the tube is press fit on the collar. The parts:
I went ahead and drilled the adapter and pinned it to the barrel. Then I pinned the shroud to the adapter and welded it in place to be in compliance with the ATF requirement for blind pinning.
Here it is mocked up with a YHM Spectre Lenghth handguard over the top of it and a SWR Trident-9 under the hand guard.
The Mock Up:
It will be getting the blackout treatment with some KG this week, as I just finished sanding it smooth from the blind pin welding treatment and should be back by in my hand by the end of the week.
So far, I have bought the aluminum tube for this project. I have made the drawings for the build, and paid the machinist at ADCO their hourly rate to get this made up. I did the pinning and welding myself.
This one is made for the thread on mount for the Trident-9. The adapter threads to the barrel and then threads to the suppressor. It is feesable to have the adapter get stuck on the barrel under the shroud. I'm not really concerned if it does. I can still thread the suppressor to the adapter even if it IS stuck on the barrel. The adapter may be "stuck there" but it'll still be useable. It cost me less for the adapter than it would have cost to have them thread the shroud adaptor for the suppressor as my original plan. This way, the design can be adapted to work with the Tri-Lug adapter, pretty easily.
I don't know if ADCO will offer this service, and if they do, I don't know what the price will be. If you're interested, I would recommend you contact steve@adcofirearms.com or dave@adcofirearms.com and let them know you are interested in a shrouded barrel like the one they made for rjrivero.
This one is going to go to my brother for Christmas. The next one I have them building is going to be mine. And the third one is for my 300 AAC Blackout barrel.![]()

Here's the last picture of the shrouded barrel wearing the Trident-9. With the Trident it brings it to 17" of barrel length. The rifle is a Lone Wolf Dist. 9mm Lower with a Rock River upper. The bolt was narrowed and ramped by Adco in Sylvania, OH. The handguard is a YHM Spectre length. Eotech on top with MBUS "irons." Runs great and handles very well. Lighter than the 16" barrel version. This thing runs QUIET!
Very slick. Nice job.Originally Posted by rjrivero
