One of our guys (Tom J.) was shopping .22s today and saw a CZ with threaded muzzle. I am not clear on the model and configuation, just that it was a CZ .22 with threaded muzzle; at Larry's I think, maybe Wiley's. Marked on tag "Thread protector in box." Guess they figured somebody would steal it if on display.

Anybody here know about that? He thought it was for a tuner, I wondered if it might be an European option for a silencer.

Hi Jim, it is for a silencer. We have had a few UK and Aussie members post some pics of theirs with the "moderators" installed. I think it was stated that it was a standard thread and they could just go to the hardware store and pick out what they wanted.....and it would fit the thread.

What I thought.
Most foreign lands, getting the gun licensed is the problem. Once you have that, using a silencer is just being a good neighbor, not a gangster.

Yes, I call them silencers because the Maxims did in 1909, no matter the current crop of Internet Experts calls them "supressors." One source with experience says:

"The Maxim silencer was complicated and costly, but also very efficient. The sound of a Springfield .30 rifle was reduced to little more than the click of the firing pin, which (IMHO) pretty well allows it to be called a silencer. The principle was to allow the gas to be channeled through a series of holes into a cylinder fitted with spiral vanes where the gasses went around until they had lost the heat that causes expansion. With the gasses no longer expanding, the noise was minimal. (The silencer got hot as heck, but that was considered a minor drawback.)"

The complex shape of the Maxim baffles would make it very expensive to build now. USFA announced a reproduction pre-war Woodsman with real Maxim Silencer, but have never put it into production.

Did Tom happen to mention if the rifle in question was quite short? The most common threaded model seems to be the CZ 452 American with a 16.5" barrel. I am sure that this is done to control the overall length of the rifle once the can is attached.

No, he didn't mention or maybe I didn't register such details.

He bought one without iron sights, I assume an American, but it could have been a Varmint.

I'd love to snag one of the threaded-muzzle ones for my can. It's not the same as the standard 1/2-28 that US cans use, but adapters are readily an inexpensively available. I haven't seen one around yet, but I've still got my eyes open!

Hi,here in the UK,nearly all rifles are supplied with a screwcut for a "moderator" and is usually 1/2" unf thread,on a .22 with subsonic ammo it reduces the sound to almost nothing,and on centrefire rifles it acts as a muzzle brake reducing the "flip" of the barrel as well as quietening the muzzle report.

I have a BRNO Mod 2 that is threaded with a standard barrel with sights- it has a steel ring thread protector- from what I have learned the thread is different euro is 1/2"x20 us is 1/2"x28 ?? I would like have one on but I don't want to spend $200 plus the hassle and paperwork- I couldn't hunt with it here anyway - silenced firearms prohibited on game animals

Yeah the threads are not the same, but there's several places that sell adapters. Just thread it onto the barrel, then thread the can onto the adapter. Rimfire Technologies makes a good one just for the CZ. I wasn't going to spend the money on one either, viewed it as more or less a useless novelty, but then my local dealer shot one with me in the room. I was hooked immediately.

Tom bought a CZ .22 rifle? Well hush my mouth!

Is he putting together a USBR Sporter Class tool?

Wish both of you would try the offhand 50/25 Match sometime - you with the Savage Anschutz and he with the CZ.

CZ also had a few 17HM2 Varmints that made it into the country with threaded barrels. I heard the number was 1k.

You'll note the very nicely matching thread adapters on those rifles.

Jim...Last year (12/09)I bought a CZ 452 Silhouette in .17HMR with a stock 16" barrel with Parker Hale threads and a cap for the threads. I came from a dealer selling on Gunbroker.com. I call CZ about this and gave them a model number to check on. They said that from time to time they get special runs from the plant for a customer which didn't work out and they send them to several larger distributors. In the case of the 452 Silhouette in .17 HMR, they said they only had from ten to twenty made. In their 2010 Web and catalog they show as an option a 16" barrel for several rifles. I hope this helps...I am having a real & fake can made as we speak for my Parker Hale threads. I'll post a picture of the gun and fake can if you would like to see it.
