3 lug adaptors Login/Join

Hello,
I am really new at suppressors. I am building an SBR Scorpion and want to eventually put a suppressor on it. I want a 3 lug adaptor, so my question is; are all three lug adaptors the same?

Probably a very easy thing to see, but just want to make sure.

To be clear, you’re asking about the 3 lug mount that is attached to the muzzle, not the 3 lug adapter that goes on the rear of a suppressor, right? If so, they should work if they are designed to HK spec. Personally, I use the HK Parts 3 lug mounts, but there are others that work. A lot of people seem to like the ILWT ones. Might be easier to ask for ones that have problems, or ask about a specific mount you want to buy.

To expand a bit on Dwill104. From the point of 3 lug on 9mm provided its HK spec they are all the same in terms of suppressor mounting on the gun side, that's the actual point. But when buying one you have to match the barrel end of the adapter to the threads on your barrel (on a scorpion this is a generational issue) and many vendors also offer a 3 lug adapter that is 3lug and also have 1/2x28 threads at the same time. I don't like these FWIW, but many seem happy and they are more universal in the sense of you could mount something that doesn't offer a 3 lug mount on the suppressor side. I've used a number of different mfg. and really noticed no material difference. I like the rugged ones since they have the go/nogo markings and the ILWT ones. But they all are essentially the same under the covers.

Sounds like what I thought. I was thinking of getting the HB Industries “HK 3 lug adaptor”. I wanted a silencer that would attach to that instead of threading a silencer on.

I guess my question is, will that lug work on any of the suppressors that attach by a 3 lug adaptor?

One more question: How is one secured on the end of the barrel? Loctite?

Thanks in advance.

It should. Personally, I just torque my 3 lug mounts on. Don’t use loctite.

How much torque do you use?

I've never heard of any suppressor 9mm 3 lug mount not working with an HK spec 3 lug adapter (45 cal and other 3 lug designs are not covered in that). I have personally experienced a barrel machined with 3 lug that won't mount a certain suppressor, but that's really a mfg. defect in my mind.
I don't ever have any intention of removing a 3 lug adapter once mounted so I use red high temp loctite.

I torque mine to 20ftlb's. But in reality the problem on the CZ is holding the barrel so just a bit more than snug with some loctite will be fine.

I got a Rugged Obsidian last year and---because the can came with a gift card promo for the Rugged website--I picked up one of their 3-lugs. It's HK spec, but has visual markings to help confirm the can is mounted properly. At first I found this gimmicky. After using it, though, I've come to appreciate it.
