Well I got my suppressor shipped out today to them for the conversion of my AAC can. Been on the wait list for awhile now.

Can't wait to get the can back and start using it again

Doc
Mount conversion or recore?

Superb craftsmanship, regardless.
 
Fortunately I don't need any type of suppressor work, but if I ever did Ecco would be at the tip top of the list. Absolutely everything I've ever seen or heard about them and their work is top notch.

Please post pics and an update after you get things back.

Mount conversion. Mine was sent back 3 times because it would never stay locked up. Then they went out of business so the can hasn't been used since.

I have two AAC cans going in this batch - an M4-2000 and a 762-SD. Both are getting DeadAir Keymo adapters.

I got lucky with AAC muzzle devices. My 18T adapters for the 762SD locked up good and it took a couple tries, but I found 51T brakes that locked for the M4-2000. Still, no reason not to modernize. The 762-SD will become a dedicated can for my LMT MWS and the M4-2000 will bounce between my primary night vision carbine and something else. It will take some of the load off my 556 SOCOM can.
 
Well got my can back today. I can't say enough. It looks amazing. I can't wait to get it out to the range. Will never hesitate to use them again if the need arises.

Wife just signed for it back from UPS about an hour ago. 24 days from when it left my hands to getting it back in my grubby little paws.

I got on the list in December and my SAS can is on the way back to me, I should have it tomorrow. This is the pic I was sent...

I opted for the YHM Kurz mount since I have a Resonator K in jail. Now all of my rifles will use the same mounting system.

Might be kind of late to ask as thread seems to have died but - what color moly resin is this? Coyote Brown or Tan FDE ?? All the color pics I find seem to vary. Close to magpul FDE is what I would prefer. My SDN-6 is headed to ECCO next week.

I honestly don't know, I told them to hit it with whatever color they wanted. The can was cerakoted FDE when I sent it in so I imagine that's what it is. The color isn't much different than what it was.

It's more of a darker tan. Then desert.

Pics suck

Doc
 
Pics do suck and that's what got me going as the pics Jerrica sent weren't consistent, lighting etc.
Oh well, I'm not an interior designer that cares too much about matching that closely anyway. Cans are usually covered anyway.
And if anyone else is interested I got my invite from ECCO today and was in the que 2 months to the day.
Thanks for the replies!

Sounds like the wait times have shortened significantly. Wait times were 6+ months which is understandable with one guy doing all the can work.
 
I am on the wait list for an SDN6 fix. My T51 doesn’t hold at all. Is a recore worth doing? Does a recore make the SCN6 significantly quieter or lighter?
(I already have an Ultra 7 and 9 so unless noticeable I probably won’t bother.)

Idk about your can but he recored my SWR Omega 30 and it was noticeably quieter and lighter(7 or 8 oz I believe).
 
I've been on the list for 18 months.. Called them after 12 months and they said I was still on the list. Still waiting...
 
I got the email that my can is to be done in the next batch. It has to be sent no later than the 10th. I’m out of town until the 15th due to family emergency. I asked if I could get into the next batch. Email as not been answered.

After going back through email files I see that my previous post was wrong. Not 2 months on wait list but 3 months from the time Jerrica added me to the queue to the email I received from them last Friday saying to ship them the can. The work I asked for is the mount conversion on an SDN-6.

Doubt if they will move you to the back of the queue. They responded to 3 or 4 of my questions last Friday. Seem like reasonable people. Just very busy.
 
I e-mailed them this morning and Jerrica got right back to me. Apparently there was some missed communication and they
said to send it in. I really appreciated the punctual response and not putting me to the back of the line. That's customer service
at it's best!

They've been great for me too. Besides the Five by Five I just bought from them if I want another suppressor and they make one that's close to fitting my needs I'm definitely buying from them.

Sure looks like quality work.
Looking forward to using it.
I also bought a direct thread adapter to use on my rem700 .308.

That looks really nice man. Give us a report on how it does on them big boy calibers
Mine has worked amazing on my 7 SAUM. Sadly it's still too much recoil for my neck after my surgery so am sadly having to sell it. It truly takes a lot out of the recoil. But it's a bit much for my neck. I can't fire more than 10-15rds without the pain coming to become too much.

Im a little late, and maybe misinformed on your can, but; Did you mention this to Nick? Maybe there is a way you could vent, or port, some of the baffles to help with back pressure/recoil.

This would be thorugh a re-core type process, I would imagine. Or, if your can is user serviceable, and you can remove the baffle stack, you could tackle it yourself with the right tooling.

Just a thought; sorry your injury is putting a damper on your fun.
 
I did not mention this since I didn't know that was even a thing. Sadly it's a AAC sdn6 which is not user serviceable.

Doc
 
I had them repair my Gemtech that had the quick attachment stuck in it. Had them cut it out and make
it thread on. They did an awesome job on it! Highly recommend them!!

Porting baffles will not reduce recoil, and will make the can louder. Also, reducing backpressure in the suppressor, will increase felt recoil from the gun to the shooter. The more gasses the suppressor traps, the more it pulls the gun forward, reducing felt-recoil. Kind of like a 1-chamber muzzle brake vs. a 4-chamber muzzle brake. The 4-chamber will always reduce recoil by a greater amount, because it has more surfaces and surface-area for the gasses to impact and push on as they exit the muzzle.

So after I wrote it, I thought about it. I think my wording was just wrong.

I understand your explanation fully. But not all cans recoil the same. As, with the amount of cans you showcase, I assume you know. I didn't want to edit the whole post after posting it, and was willing to take half the flame.

Nick's baffles may be more efficient, and or effective at reducing recoil, compared to the stack in the can in question. He also might have a good recommendation for something different.

Just was a downer to hear, on what was a good day for me, so my mind immediately went to ways to fix it.
 
Got my AAC SDN6 back from ECCO a couple days ago with new bravo mount. Also got one of their Gyrex taper mounts and helical ported muzzle brakes. I got the taper mount and muzzle device mostly to see it it lessens any POI shifts remounting cans but the comments about recoil reduction lead me to wonder will the ECCO brake will reduce recoil over something like a SiCo ASR flash hider in the can? The fact that the SDN6 with a SiCo mount and a Rifles only HAD cover weighs 1.98 lbs will probably reduce felt recoil more than anything. That can is heavy!

Absolutely, not all cans are created equal. My Sandman-S cans do not reduce recoil (or DB volume) to the same level my OCL Hydrogen-S does, even though they are both (roughly) 7” cans. Internal volume, baffle count, & design plays an inordinate part in this, as well.

No, once the muzzle brake is inside of the suppressor, it all acts like a giant muzzle brake. Some say it could affect it scientifically…Which means you’ll never physically notice the difference, because the measurable amount will be so minuscule.
 
I got my sdn6 reworked with the TBAC CB mount. How do you guys secure the adapter to the can? Just torque or lock tite or what?

I put mine in a barrel vise and gave it some torque. Also put a bit of anti seize on the threads.

Rocksett is my go-to, locktite won’t handle the temps unless you only shoot a few shots at a time before letting it cool.
