CZ 452 Suppressor help please

I am currently winning the auction on a CZ 452 American 17HMR with a threaded barrel, less than a day left. I just bought my son a 457 scout, and am going to teach him to squirrel hunt this fall. He's been deer hunting with me for 3 years (observing), and if he does well during squirrel season, and I'm comfortable with his shooting, I'm going to let him hunt the youth deer weekend. I have zero knowledge of suppressors. CZ makes one for $339. Is there a better option for me? I want cheap and good... not expensive and good btw...please. I wouldn't spend more than $339.

threaded 1/2" x 28

Thanks :)

As long as it is a user serviceable design you are probably OK no matter which you choose. Forget all of the FRP and other nonsense (FRP = first round pop) shoot SV ammo and it'll be satisfyingly quiet. Maybe check in the NFA section of this site.

Enjoy your new rifles!
Oh.. Forgot to add.. WELCOME TO RFC!

FRP is not nonsence, especially for a hunting rifle but that said, FRP usually isn't as pronounced on a rifle, it's more of an issue with pistols and as Jammer22 pointed out, be aware that 17HMR is still going to be on the loud side because there is no subsonic load for it.

Maybe more important then the suppressor model itself is the manufacture you buy from? You want to buy from a company with great customer support that will likely still be around years from now as opposed to a start up that may or may not go belly up in 2 years.

For a rimfire can, user serviceability is a must. I'd also prefer to stay away from aluminum baffles. They are lighter and cheaper but they limit your cleaning options. Also, a lot of aluminum core rimfire cans are not rated for 17HMR. I also prefer "K baffles" over "monocore" construction. Partly again because of cleaning and partly because monocore suppressors typically do not sound as good (and get considerable FRP) on pistols. Not as much of an issue on rifles

All that said and keeping your budget in mind, I think YHM Stinger is probably a very good option for you. Street price right around $300, user servicable, SS K baffles, 17HMR rated. YHM has been around for a good while and don't see them going anywhere anytime soon and they have very good CS. Their whole business model is to make quality, affordable no frill parts.

Another option to possibly consider... if the budget is tight and you are a handy "do it yourself" type, you might want to consider making your own suppressor using a form1?

Lastly know that even before COVID-19, suppressors have been flying off the shelves and most dealers have very little in stock and manufactures have been having a hard time keeping up with demand. What that means to you is, if you have a local dealer that has any 17HMR rated rimfire suppressor in stock, that one may be your best bet?

My CZ isn't threaded, so I use another rifle. As I also have the Ruger MKIV 22/45 Lite, that's what I wanted—a light suppressor.

I bought the SilencerCo Warlock II, all aluminum, tube and baffles. The first time I tried to clean those aluminum baffles, I despaired. Can't go ultrasonic, can't use the dip. Found a great regimen later and now love it.

Again, they are discontinued, and some people want stainless steel to tumble, dip, or clean ultrasonically.

But they are between $179 and $199 right now on the well-known broker site that I'm not sure I'm allowed to name here.

If you want to be able to use it for other calibers and full auto, though, look elsewhere.

I have the Yankee Hill Machine 22 Stinger and love it. Stainless steel baffles, aluminum tube. Easy to disassemble and clean. Doesnt negatively affect accuracy. Rated for semi and full automatic in .17HMR, .17HM2, .22LR, .22WMR, and 5.7FN. ~$300, plus the stamp. Standard velocity .22LR sounds like an air rifle.

2nd the dead air mask. Buy once cry once. Repeatable accuracy. What most cans are compared to. First round pop is rare. Titanium and stainless. Doesnt stick in tube.

The price doesnt bother me. The wait and stamp is annoying. Pay the extra few $$

Mine has been durable quiet and accurate.
The question I ask when I see the question about suppressor when people ask which one is the best..it always answered which ever one the person has..

I ask what other ones do you own or have owned ?

It seems to me, based on some comments, that as a hunter, not a plinker, I really don't need one. I was concerned about noise for my boy. Maybe that's not even an issue...
I hope to...teach my kid how to hunt without killing his ears. I thought that a suppressor my be nice in a 17 HMR, but I have zero experience with them. ... How much different is the noise between the two? Do I even need to worry about the noise of a 17 HMR?
What about a non suppressed 22 vs a non suppressed 17 HMR? I had zero intention in suppressing his 22. It's super quiet (as compared to what we're used to...centerfire rifles). ... the intention is to always protect his ears. I've never wore ear protection, except when practicing, never in the woods... But I'd have no issue with a 22 ever. Is a 17 HMR much louder than a 22? As a dad, will I notice that difference so much that I'm worried about his ears?
You are wise to be concerned about your son's hearing.

Shooting a 22 LR unsuppressed will contribute to hearing loss. Hearing loss is cumulative and irreversible. The louder the sound, the shorter the duration of exposure required to cause hearing damage. For example: At 140+ dB hearing is damaged instantly; whereas one can be exposed to 85 dB for 8 hours in a day before hearing damage occurs. This is why hearing protection is required in many industrial environments - I've been there, I'm there now.

The American Suppressor Association has a lot of good info. For example:
Image

You can find this all backed up by OSHA and medical studies...

Just because a 22 LR shooting SV ammo out of a 16 barrel produces ~140+ dB of sound doesn't mean that the shooter's ears - yours and your son's - aren't being harmed. There isn't any reality in 'we're used to shooting CF rifles that are much louder' (which, by the way, usually produce ~167 dB of sound) - its harmful. The damage is done.

The 17 HMR is louder than the 22 LR unsuppressed. It's louder suppressed, too, using most all rimfire suppressors. But 17 HMR suppressed is brought to hearing safe levels in the 125 dB range, whereas 22 LR can be made stupid quiet, 115+/- dB, as others have pointed out. Suppressed CF rifles are often only brought down to 135 - 140 dB. At those levels, harm can still be caused, and repeat use may warrant additional hearing protection.

I recommend getting two "cans," one for each of you. Most all modern rimfire suppressors will handle the WMR and HMR cartridges, and are going to provide reasonable to great suppression. Really, we're getting to the point of splitting hairs. Pick one or two that have features you like and go for it.

Else, put the muffs on or the plugs in and save his hearing. Electronic muffs are nice because, like with a suppressor, one can still hear their surroundings - it's just not the same, though.

PS - the best time to buy a suppressor is always 6 months ago. ;)

I want a 17 HMR so I can shoot at further distances. I’m going to head shoot, and whatever we see, I’m just going to let him shoot at anyhow. If it’s too far for him, I’m going to shoot. I’m so lucky to have a son who will sit out in freezing temperatures, without a gun, and just love being out there, and being a part of a hunt. He’s going to love this. I’m mostly just teaching him by example, shooting squirrels that are too far for a .22, and ones he can’t see. I love the advice. Keep it coming. I had no idea about the stamp...that’s nuts imo. Not that I won’t do it, but the whole idea of a suppressor is no longer that appealing for my application.

I’m a best for the $$$ type guy, and I didn’t want to do semi-auto with a 10 year old, so CZ I believe fits the bill. I’m brand new to this forum, but am a regular in others. I hope to be able to shoot cheap, and teach my kid how to hunt without killing his ears. I thought that a suppressor my be nice in a 17 HMR, but I have zero experience with them. Have %%%% lots of 22s. How much different is the noise between the two? Do I even need to worry about the noise of a 17 HMR?

There is a drastic difference in decibels between suppressed and unsuppressed, and subsonic and supersonic. Any ammo that has a muzzle velocity less than ~1,115 FPS (that includes standard velocity .22LR) is going to be very quiet when shot through a suppressed bolt-action rifle.

What about a non suppressed 22 vs a non suppressed 17 HMR? I had zero intention in suppressing his 22. It’s super quiet (as compared to what we’re used to...centerfire rifles). I wouldn’t dare let him not wear protection while shooting in my scopes in with my .270, 30/06, and 300 win mag. I’m embarrassed to say I’ve shot right next to him when he didn’t have time to put them on while hunting, several times, but the intention is to always protect his ears. I’ve never wore ear protection, except when practicing, never in the woods... But I’d have no issue with a 22 ever. Is a 17 HMR much louder than a 22? As a dad, will I notice that difference so much that I’m worried about his ears?

Well, I won the auction on the CZ 452 American 17HMR. Now I'm wondering if I made the right choice. I didn't win the 452 scout for my boy, so I bought him the new 457 scout. Now I'm having buyers remorse. I guess if it doesn't shoot well, I can trade it in at the local gun shop and get a 457 American? I bought a new scope for each. Got the Leupold Freedom Rimfire 3-9x40, and the Alumina cover kit for both. I would have bought the 2-7x33, but couldn't find any Alumina kits for a 33. Went with the Warne 7.3 rings for him, and mine comes with rings, and 1 5 round magazine, and 2 10 round magazines, so I didn't need rings. I guess I'll see how it shoots, and go from there. I guess my concern is the fact that it has opposite safety, and with the guns so similar, my boy may mix it up sometime??? IDK... I'm probably just being dumb.

Seems like it’s been taken care of, or not used much. Hope she’s a shooter.
