Can anyone tell me what's needed to mount this Omega 9K like they did here in the video?

I'm going to set mine up the same with the handguard and all and want that same flush fit.

I have had mine since late 2015 so I must have the old thread pitch.

Got the thread adapter and the extended hand guard on order. Also ordered 5 Manticore Arms magazines, a yetiworks grip and a factory folding stock. I want to try something's different from the CZC adapter/magpul setup. It works fine just puts my head a little high and it doesn't look natural with the firearm.
I will be running an Omega 9K. Pretty excited about this O0

How do you keep the tread adapter from unscrewing out of the suppressor and staying on the barrel? Should the adapter stay on the barrel can you still remove the handguard? Or can you still reach the barrel threads with the guard in place?

You don't. Either use the piston with spacer, or use a 3 lug system. Or just let the direct thread adapter live on the barrel as a muzzle device.

This will make you have a bad day. If you want the suppressor to live inside the carbine handguard, use either the fixed barrel spacer or a 3 lug. The direct threads do not come off the barrel as easy as they come off the suppressor.

So you are saying I will need more than the fixed adapter to safely use it? I was planning on leaving this suppressor on like a muzzle device. But it will fall off? Sorry, never used one before this is a first.
I felt like I got ahead of myself so I canceled the order on the extended handguard until I have more info. I thought it would be simple but I can see how it would be a PITA to get things on and off the barrel with the extended guard in place. For now though I am stil planning on the direct thread mound and Omega 9K. Is there anything I'm missing? Or will that allow me to utilize the can properly?

I bought the full hand guard version as well as a silincerCo Omega 9k silencer to go with it. I contacted SilencerCo and they sent me this link to get the adapter to match the end of the barrel to the silencer. I have not bought it yet per waiting for the form 1 to come back for the sbr/silencer paper work.

But from reading this, sounds like I may be in a little bit of trouble if that needs to be threaded on the barrel and then the silencer, getting everything tight may be an issue. Although wondering if you can thread that adapter onto the silencer first, and then onto the barrel and not have any issues. Honestly I do not have everything in front of me, gun, silencer, adapter, and I've never been down this road before, so i guess time will tell.

^^^ yeah I ordered the same adapter today. I'm fine with the factory hand guard as it still looks nice with the shorter suppressor and doesn't add additional weight. I just want the ease of use to be there as well in terms of taking it on and off. But I don't want it falling off while shooting either.

If you attach the suppressor to your barrel (with the direct thread adapter installed), when you go to remove the suppressor, the direct thread adapter will unscrew from your suppressor before it unscrews from the barrel. You could eliminate the issue by gluing the adapter to your can or mechanically locking it to the can somehow, or just never removing the suppressor again.
Like others, I went the DT adapter route and ended up having to use pliers to remove it from the barrel after it would unscrew from the suppressor.
Imagine having to use pliers to get your direct thread adapter off of your barrel when it's ~6" deep in your handguard. But like I said above, you could just leave the DT adapter on your barrel as a muzzle device.
-
Would it be possible to cut a slot in the factory handguard so a small spaner wrench could be used? Like in the valley between the pic risers on the rail?
HB industry's hand guard is a free float design. At least you would be able to remove it to gain access to a stuck adapter.
Wonder if a custom thread adapter could be made with a torx bit cut out as part of the bore hole.
-
not sure, its just plastic, so could be cut to get some thing in there to release it. Ive just planned on leaving my suppressor on it and just go from there , if i need it off, i can figure some thing out.
On the flip side, wouldnt mind getting another scorpion and doing the HBI hand guard.

You could notch the fixed mount adapter like the flaming pig/kak flash cans. This will allow you to stick a thick metal ruler down in and turn it like a flat head screw driver.
Just clean up your threads after you make the notches.

That's a much better idea lol. I've been contemplating a similar setup but that was a major hangup.
357 - You'll need a rifle barrel nut socket to install the longer handguard but you'll have a nice setup. The problem isn't getting everything tight. The problem happens when removing the suppressor. Sometimes the barrel adapter will unthread from the can & stay on the barrel. With it recessed in the handguard it makes it difficult to remove + it'll block the barrel nut so you can't remove the handguard.

3 lug on the barrel and the 3 lug mount on the can.
Just did this to my Evo with the carbine handguard and it worked perfectly.
This is the adapter I got:
https://www.store.silencerco.com/collections/silencer-accessories/products/3-lug-mount?variant=35515080017
I got the three lug from HK parts.
I wouldn't do the direct thread method with the carbine handguard, I had one of my suppressors walk off while I was shooting (no baffle strike thank goodness) so I'm going to 3 lug from now on.

Wanted to reply to this per my previous post and another thread.
I got my can paperwork back monday, brought my full length hand guard scorpion into the shop today to mount the omega 9k on it.
First, it fist exactly like it does in the vid on the first page per Mac's setup. I bought the direct thread adapter as well and everything fits perfectly, BUT with that said, its just for looks, its totally not practical to keep the can inside the hand guard because you cant really get a good bite on it to get it tight. Ive got a seat belt type strap wrench, little rubber channel locks, and some rubber hose and a pair of normal channel locks all to crank it down. Where I thought I had it tight a few times, a good wrap on it with some light rubber exam gloves I usually keep to work with, got it to spin off and come loose. So after a few more attempts ive gotten it pretty tight. Tight enough where it wont come off with my hands, but I can only imagine after a few shots it coming loose.
The answer to this issue is, which people have been awesome on this forum and informed me about on a different thread I posted, would be the HK tri lug setup, and just have it a quick attach and its tight. I feel like keeping mine inside and having to shoot some and then cool, tighten it or make sure its tight, then shoot again, ill never really get that feeling of being able to shoot it consistently and securely . Which I think what I should have done to begin with is just to get the free float setup from HBI hand guard, and put the 6.84" flat guard on. Looks tits and I should have just done it this way, but I really loved the look of that scorpion that Mac had in his vid, but for ease of practicality and safety, a tri lug or hand guard would be better imo.

I appreciate the writeup. I ended up cancelling the order on handguard and just plan on going with the can in a direct thread mount. But I'm also going to use some form of non permanent loctite thread sealer to keep it from backing off on its own. Not sure which one yet, but I don't want it to easily come off, but break loose when needed.
I honestly don't plan on shooting it suppressed much. It's straight up for the house in case I ever have to pull the trigger inside I don't want to be left hearing impaired for life. Since the Omega 9K is not user serivaceable I will limit the rounds I put through it.

I think you might find that shooting the Evo suppressed is more enjoyable than you think. The gun does very well, especially with sub sonic rounds. As for it not being user serviceable, that is a good point however if you have a 300 blackout, you could put a few full power rounds through it and it should be good to go just like any rifle can. Just a thought.
-
I've never had one before, could I put it in a supersonic cleaner or run bore cleaner through then clean out with a spray or would I risk rusting the inside out?

Centerfire suppressors do not generally need cleaning. Centerfire rounds are nowhere near as dirty firing as rim fire cartridges. I wouldn?t put too much thought into it.
