Hey guys, I'm starting the paperwork process to convert my DD MK18 pistol to a sbr. I figured I should probably get the process started for a suppressor as well. I'm not too familiar with them, this would be my first suppressor.

It's main role would be sitting on the MK18. However I do have a grendel ar for hunting and a 6.5 bolt gun that I'd use on too if that made sense.

So my question to a degree is, what's the best suppressor for the MK18?

Also, is there one that may offer some flexibility and still get the job done?

TBAC was what I was researching prior for my 6.5s and I liked what I read about them, but never went for it. Anything from their lineup that would work?

Appreciate any recommendations and input.

Morning,

I own a SilencerCo Hybrid. It is fine for what it is--a multi-caliber can. That said, if I were in the market for a new can, I would not buy the hybrid again. I would probably go with something more caliber specific. A multi can is going to be on the big and heavy side.

I did a lot of research trying to find a good can that can serve well in those roles.

I went with the rugged micro30 because of their lifetime no questions asked warranty, lower back pressure and the best at ear sound levels of the cans I have found in that 6.5ish length range besides an OSS which I just wasnt into.

Going to have to agree with the rugged micro 30 on this one, or the razor 7.62 if you don’t need the modularity and want to save a couple hundred bucks. Rugged cans are awesome for all around durability especially on an SBR, they also have a great mounting system for repeatable POI if you decide to throw it on a precision gun.

I haven’t gotten to see the new Dominus from TBAC but if it’s quality is anything like their ultra series I would imagine you couldn’t go wrong with that either.

If there is no budget restriction TBAC is the only answer to me. If you do have a budget in mind YHM is hard to argue with. Turbo K and Resonator k with whatever mounting system you prefer and run with it.

Honestly that is kind of where Im at right now. If budget allows TBAC. For everything else there is no reason for me to look anywhere except yhm. They’re so cheap and perform so well that i just couldn’t justify saying spend 3-500 more on any other brand except TBAC especially now that the dominus exist.

Currently i own a TBAC 30CB9, SiCo Omega, SiCo Hybrid, and have a turbo k and resonator k in jail.

Handled the TBAC Dominus SR and CB at SHOT and asked my dealer to order one of each. I really only need the CB, but want both. I picked up a .22 TD today and have an Ultra 9 and 338 in jail.

if I were buying one .30 can today it would be the Dominus SR. i have another .30 can that is great but heavy.

Knowing what I know now I’d stick with TBAC and specifically the Dominus SR. I should have gone Rugged instead of my other heavy .30 cal can a couple years ago.

TBAC and Rugged offer excellent solutions. I don’t have a Rugged (should have bought one), but a good friend/dealer shoots the hell out of Rugged products.

Thank you everyone for the input. I literally re-ignited the search the other day when I posted this, funny to see TBAC had just come out with the Dominus. That certainly seems to be the winner for me. I do like the Rugged as well, and like that they are nearby in SC. But I think I'm going to try and find a Dominus first. Hopefully I can grab one when they hit the market

I almost pulled the trigger on a Surefire 7.62 Socom Mini2 yesterday for a 10.3" 5.56 build but I am finding it's not hearing safe. That got me wondering, is there any compact cans (sub 7") that are hearing safe on a supersonic 10.3" 5.56? Or close to hearing safe?

From everything i've read you can get close to 140ish but hearing safe as in blackout numbers or something i'd feel comfortable shooting without earpro for extended periods of time? Nah i don't think so. You want a hearing safe 10.5~11.5" 5.56 it's going to require a pretty stout can to do so, even then you're fighting port noise as well. Either increase the length or diameter. I went 11.5" for reliability concerns and more rail space but the Turbo K gets a 11.5" close i'm not sure about a 10.5" Griffen Explorr 224 is probably a good one to look at.

Closest comparison i can find.

I have a non-supressed 12.5" now but was looking to do a block1 w/o a KAC M4 can. I'd like to do a short 7.62 can with a good QD but I think I'm looking for a unicorn.....


Edit:
Holy shit, I had no idea the ear was 10dB higher than the muzzle.

Port noise man but yeah a decent 223 can would do well i'd just wear ear pro outside of like hunting or small strings of fire.

I'm waiting on my turbo K and resonator K. Turbo K should be here relatively soon if COVID19 if it doesn't take up the ATFs time. I have fired my 11.5" and a 10.3" i sold my to my uncle and holy God it is freaking loud. Buddy of mine finally got his Micro 30 in which is what i was originally shooting for and it basically sounded nearly unsuppressed kind of like how the sandman K seems to sound on short ARs.

While I have not shot an abundance of different cans what I have learned being on the hide for 10 years is that any supersonic AR is not hearing safe. This is especially true if one has the idea of shooting an AR suppressed without ear pro all the time such as range days, plinking, etc. The only caveat in my eye is a person grabbing a suppressed AR to use for personal defense which in that moment it's not logical to put on ear pro.

I do form 1 cans which give a person a lot of options and you can build a suppressor for very specific uses. This can mean building a can that has a larger diameter, more length and smaller diameter bore.

Like mentioned above and other threads I've posted in......after shooting a 5.56 pistol unsuppressed for just 3 shots one time I cleared it and was done. I was doubled up on ear pro but the experience was so obnoxious I would never shoot another unsuppressed AR pistol unless I needed to defend life and that was the only/best option.

I should have known better. My AEM5 on a 16" isn't what I would consider hearing safe and it's wonderful can. It's not too bad for a few shots, but I still use roll in plugs.

I guess my alternative would be to swallow my pride and build a 300BO with Subs, but I have a deep dislike for the caliber. Maybe a .45 PCC instead..... problem is, neither are going to scratch my block1 itch.

For a mk18 you cant get much better then the tried and true Surefire and KAC cans. I'm sure the new TBAC offering is excellent also if its anything like all their other cans.

I also have the micro 30 from Rugged. Its noticeably louder on the 5.56 guns with more flash. And also much louder to me on 308 and mag rifles.

In the short config it does not perform as well as the dedicated mini cans. RC mini and KAC CQB are noticeably better in sound, and flash reduction. In the standard length config it still doesn't do as well as the Surefire, KAC, AAC, (TBAC on a bolt gun) etc. The rugged micro 30 is kind of a let down for me personally with all the other cans I already have. Maybe if I put together another 13.5 or 14.5 308 gas gun and want a "blast reducer" in the short config, it would work well. But it doesn't do anything better then the Surefires, KACs, TBAC, etc. I would rather have another m42000 on a mk18 then the rugged micro 30.

That's not hard to do really. Most of the 5.56 specific cans are below 7" mounted.

Saker 5.56. AAC 556SD. 7.62SD. I don't have one, but I'm sure that TBAC steel can will too. All are abuse type cans (that's what I call anything that has basically no restrictions on firing rate). I have an AAC 556SD on an 11.5 that I keep handy. It was a cheap can and the mounts usually suck balls but there's a trick (that doesn't involve work). Buy ten mounts, pick the best one, send the other 9 back. I know that sucks, but it's the best way to make an AAC can work right. IMO Saker is much better and you have options on the mounts --apparently they recommend the ASR now but I gotta admit I like the Trifecta better.

Not sure about TBAC Ultra5 in 5.56 but the 5" in .300BLK and I THINK 7.62 (don't quote me on that) is JUST at the hearing safe level. Remember that level is only for intermittent dB, sustained sound over time registers different on your hearing. IMO it still sounds a lot like a gunshot but it takes the bark out enough so it's not really a problem, especially for a social rifle. More a loud abrupt pop than a typical snap. At least for me.

Ultra 9 is by far the best. It adds 7-8" w/brake. Ultra 7 will be less than 7" installed. Nothing is lighter and there is no better constructed Ti can. That's their shit in spades.

IIRC, 5.56 is one of those oddball rounds like the .357 that's just louder than you'd think. But shaving several dB's off the blast sure helps and it doesn't take a long can to do it, though the longer ones do work better.

Don't know about the KAC 5.56 cans, but the 7.62 QDC is one of the best all around cans for the 7.62. It ain't cheap and others may disagree, but I have several of these fuckers and that one is the titties in more than one area.

There's a lot of good options really.

But for SBR use that's not a .300BLK (relatively low powder/blast per case, super or sub) I like something steel.

Oh, for budget you can't beat Elite Iron and they don't really belong last... They're not really a budget choice, just able to keep prices down by using 316SS (more than sufficient, trust me). Dale is a metallurgist IIRC and I have his BMG can and the fucker is a tank. Supposedly his 6.5G can is badass but I don't have one. He'll also index the can to the rifle if you go direct thread.

Here's some images of them installed so you get an idea of size mounted, I don't have 'em all pictured but these three get the idea across.

Saker (probably best all around for the price, lots of options, especially w/7.62 but I prefer caliber specific, they just work better).

556SD (a beater that works).
IMG_1046.JPG

7.62 SDN6. (This one used to be the shit when it came out... Same mount issue but it works and it works well with .300BLK).
IMG_1045.JPG

TBAC .30Ultra5 (there's too much shit on this one to really see but the whole can is in the picture, basically weightless).

That’s the nature of 30 cal k cans on short 5.56. You won’t find one that sounds great. If you’re wanting shortest OAL with the best suppression you can get for said k can especially on 5.56 you’re gonna need a dedicated 5.56 can. Every 30 cal k can i have seen on 5.56 is hella loud. Which includes my buddies micro30 but watch a sandman k video or Vox K and it’s apparent they’re just loud.

I probably sound like a YHM fanboy at this point outside of my usual praise for TBAC but I’m not sure there is a better 5.56 k can on the market for than the Turbo k. Especially when price is considered. It meters incredibly well for something so small and the tone from every reviewer i have seen always seem so surprised at how quiet it sounds. NFA review channel, suppressed nation, the wound channel, etc. that can for $350 has some astounding reviews. It’s also so cheap that i picked up the resonator K for my 12.5” grendel, and will likely run it on my 7 SS during hunting season as well as the 16” 308.

I agree. That's why I have never recommended a "do all" suppressor. Get the can for the task at hand instead of trying to make one work for everything. If your funds allow of course.

There’s lots of great choices listed above. I wouldn’t discount anyone’s opinion or advice. As you research suppressors, you’ll find that no can does everything “best.” Each individual can has areas where it excels & where it fails to reach the levels of performance found in others. This is what we call a series of trade-offs.

A few years ago, I bought a Surefire SOCOM II 7.62 RC2 & performance has been great. I don’t regret it in the slightest as it was meant to be a “do it all” type can. I made a list of pros / cons & the RC2 met my established criteria best. I’ve shot to 1K+ w/ it & no accuracy issues at all. I’ve also beat the dog piss out of it mounted on an M4. It just keeps humming along. Some don’t care for the QD mount, but thus far mine has been flawless.

Make a list of your priorities & pick something. There really are no poor choices listed that I’ve seen. This isn’t the time to be cheap; this is an investment so choose wisely.

*I’ve shot the KAC cans a little & I’m really impressed by their products. The MAMS brake kicks ass by itself too.

I got YHM 5.56 can 10 years ago and it's still working great. The only thing i dislike it weight 20.4 oz. Im in the market to get short, less weight, work multiple guns. Dominus Sr is impressive weight around 12oz. Not a cheap Can but the wait is killing me. Ordered 338 ultra sr last june still waiting for the stamp. If the Dominus came out last year I would have bought it instead of the 338 sr. 338 sr is a bit over kills. Does anybody know if i place order Dominus sr right now what is the estimate to receive the serial number?
