The Best Suppressor for the Money? - YHM Resonator K
Updated
14 months ago
Good morning everyone, this is John with gun.deals, and today we're going to be taking a look at the YHM Resonator K.
Full disclosure on the YHM Resonator K is that this is my personal can, I paid my own money for it, I went through the nine months and one day e-form for waiting period on this can. I do have a relationship with YHM, I am a dealer for them, however, I paid full retail price for this, but I have bought a lot of muzzle devices, adapters, accessories, so on and so forth, at that particular cost.
Getting into specifics on the Resonator K, if you're not familiar with YHM's lineup they have a wide variety of suppressors and they just released a few more as well, but their Resonator line is kind of one of their older lines, so they have the R2, which I believe is the full size can, is about eight-nine inches long, also a fairly larger standard size 30 caliber can, and then the K can, which is stands for Kurtz, which is German for short, so we eventually get to the Resonator K, which is about five and a half inches long with their included QD adapter here. If you use a shorter adapter or their Kurtz adapter, so you can have the Kurtz/Kurtz can, it's just under five inches long, so it can be very, very compact if you want it to be, depending on what you're using to mount it to your gun.

The material that we're using here is mostly 17-4 stainless steel, which is a very good, durable material, but the initial blast baffle, the very first baffle right here, this is made out of inconel. Inconel is incredibly heat resistant and it maintains its mechanical properties much better than 17-4, so for the component that takes the most damage overall it does make sense to make that out of inconel. So, you do have a welded body, it is a one piece body, it's not user serviceable, the only thing that is changeable on it is the actual mount itself. Overall, 17-4/inconel for the construction means that you do get a very, very durable, very small can that still comes in under 13 ounces, even with their larger QD adapter, I believe, without the adapter, if you're using a different one, it goes down to like 10.8 ounces, so a fairly lightweight and small can that still does anything 30 caliber and smaller.
Talking about calibers, it is rated all the way up to 300 Remington Ultra Mag from a 20-inch barrel, so basically anything 30 cal and smaller you can absolutely shoot through this, so 300 Win Mag, 300 Remington Ultra Magnum, all the way down to 17 HMR. I shot this primarily with 5.56 and with some 7.62x39 as well, as some 7.62x39 Subsonic. As far as design features and accessories go this is compatible with almost all of your industry standard mounts at this point, so 1.375x24 in the back end. It does come with spaces for a spanner wrench, and it does include two spanner wrenches in the box, so you can run YHM adapters, you can run Dead Air adapters, literally anything that has that 1.375x24 thread pattern will mount to this can, so any sort of mounting that you like you can do. It does come with one of their QD adapters as well as their longer adapter, they do sell a Kurtz adapter as well, so you can get a KK can that is about five inches long and about maybe 11 ounces or so, so you can get a very, very small, lightweight package or you can run any sort of adapter that you want.
Because this is a welded end can, because this is a one piece body, you're never going to be swapping that out to something else, a different size or a flash hider end can or anything else like that. Fortunately, it is kind of cut in the front to redirect some of those gases, so it does do a decent job of flash reduction, in fact, much better than a lot of dedicated flash hiders do, but it's not necessarily going to be the ultimate top tier in that regard. As far as durability goes, as far as price to performance goes, this is going to be one of the best cans on the market with an insane level of versatility because it is basically rated for most common rifle calibers out there, anything from 5.56 to 300 Blackout, 308, so on and so forth, is going to work really well.
The main selling point of this can is going to be a combination of the fact that it's not very big, which is going to hurt you in terms of sound reduction, but it is a very durable 17-4 stainless steel with inconel blast baffle in combination with usually being sub 500 dollars, meaning that you get a lot of versatility, a lot of durability, a decent level of sound reduction, though this is a small can and it does not break the bank, it is one of the cheaper cans on the market that is still very versatile, usable, and is going to last you a very long time. For most people, if you're looking for a one and done rifle can that has some versatility to it, a 30 cal makes a lot of sense, and if you're in the value market, which, first, suppressors is still expensive because it's 500 dollars or so, plus tax, plus a 200 dollars tax stamp, so it is still expensive, these are not cheap items whatsoever, but price to performance is very good.
When shooting with this can, I have shot it quite a bit on both this 10 and a half inch 7.62x39 with one of their QD brakes as the mounting device, as well as the LWRC ICDI, this is a 16 inch 5,56 with one of their flash hider adapters. I have put about a thousand plus rounds through it mostly 5.56, several hundred rounds 7.60x39, some 22 Long Rifle as well, which is insanely quiet even though it is a 30 caliber can. Shooting dynamics, it definitely does add a good bit of back pressure, it is not a flow through design whatsoever, so this is going to be one of those cans that can cause issues, if your gun is already over gassed, then you throw on a suppressor on the end of it, you can get some pretty high bolt velocities, it's going to be increased wear on your system. Depending on how it goes you can get a lot of gas back in the face.

This LWRC ICDI is pretty over gassed, however, even with that plus the Resonator K, I still was not getting a lot of gas back to the face, so it was not unpleasant to shoot, you definitely noticed some because it is a can at the end of an over gassed gun, especially a DI gun at that, so you do notice it quite a bit but it's not the worst that I've seen. On one of my older, much larger, form one cans that I had quite some time ago, that one there actually had a substantial amount, more back pressure than the Resonator K does, however, this is not a flow through design, so keep that in mind if you're already running over gassed gun and then you throw this guy on there you could start to run into some cycling issues.
YouTube, for some silly reason, does not allow us to show the installation of a suppressor, but it is now mounted up there due to the magic of editing, the mounting process is very easy, it's very intuitive, you basically just twist it on until it's done clicking in place. Some of the mounts don't work perfectly, so the way that the adapters work from YHM is you basically have a very loose threading and then it threads down onto a taper and then it has a lock ring at the bottom that locks it in place, that along with the taper, the taper is doing most of the heavy lifting there, the locking ring is just there to make sure that it doesn't move.
Taper systems work very well in terms of gas sealing and locking a lot of those gases, you can tell in front of the prongs there is a ton of carbon on the system, you have a very shiny taper and then behind that there is basically none. Unfortunately, just due to the very minor tolerances in tapers and the threads or even the locking rings themselves, depending on what suppressor I'm using at what temperature, sometimes they do not actually fully lock in to the lock ring so right. So, right now, this one here is just barely away, it's like 1 of 64th of a turn away from locking into the actual lock ring itself, so it's fully locked onto the taper but the lock ring itself is not in place and this suppressor will work with different mounts so this is actually the turbo case, but some of the mounts work really well, some of them work better, worse, and there's really no way to tell which one is going to work. That's a minor problem. Even when it is not locked into the lock ring at the bottom that taper is doing most of the heavy lifting, in fact YHM has recently come out with basically just a dedicated solo taper mount and that's their new system, I want to say they call it the SRX and because it is compatible with all 1.375x24 adapters you can get it to whatever you want, direct thread, chemo, basically anything that's on the market.
The last thing that we need to talk about and probably the worst thing about this can is the fact that it is a K can, so while it is very usable and shootable, has a decent amount of back pressure without being too heavy, the worst part about it is going to be the fact that it is a small K can and it does not do an insane job of noise reduction, for that you are going to need a bigger can, more volume, slow down those gases, trap more gases, and you're going to get a reduced muzzle sound. One thing about this can is it is not really hearing safe in any configuration with supersonic ammo, with subsonic ammo it's definitely a lot better.
It is reasonable with subsonic ammunition, that no pain whatsoever, but it is still on the louder side of cans and with supersonic ammo it definitely still does a good amount of reduction, we're talking anywhere from like 15 to 25 decibels of reduction, however, it is not really hearing safe, a couple rounds isn't going to kill you but it will add up over time.
For me personally, that's not a big deal, the main thing that I am concerned about with suppressors is going to be their durability because I plan to shoot them a lot over a very long period of time, it will definitely save my hearing over a long period of time, even with EarPro because I will be shooting with EarPro, so it will still take the edge down and preserve my hearing because hearing damage adds up over time, it doesn't have too much back pressure and it's very easy to move and shoot with. One thing that I absolutely hate about big suppressors is, yeah, they sound nice but they suck to shoot with.
If you put what big heavy suppressor on the end of a 16-inch gun now you have a 24+ inch gun that's very muzzle heavy, sure it sounds nice for the couple rounds that you shoot without hearing protection on, but because I'm going to be shooting with hearing protection I'd much rather have something that is smaller, lighter, still incredibly durable, doesn't break the bank, and something that I can actually use and it's not long and unwieldy.
For most people, I think, the Resonator K is a good can if your priority is shooting and moving and doing other sort of more dynamic activities, if you're just looking for something to throw on a bolt action rifle to take it down to hearing safe levels, for hunting or whatnot, then you might be better off with a titanium bigger can that's going to be a little bit lighter, still give you really good sound reduction, good durability, and you're not quite putting the same volume of fire that I'm going to be shooting a lot of short barrels and 556 and 7.62x39, 308, whatever, through this can, but I'm going to be very, very harsh on these cans, do a lot of shooting with them. So, for me, this makes a lot of sense, especially when we talk about a value perspective.
My main reasoning for this suppressor is not actually the suppression level, it's the signature reduction while still maintaining a high level of durability, and so on and so forth.
