Greetings from a sunny South Africa! My gunsmith has recently made me a can for my 22lr Rifle and I was just wondering how quiet it should? My barrel length is 16 inches and I have to date only tried Rem Subs. This thing is not as quiet as I expected and I was wondering if they vary according to manufacturer? Many thanks.

A good can on a Rimfire should produce no more sound that the click of the firing pin hitting the rim and the ding of the bullet hitting a silhuette.

Thanks Drewhenrytnt, I think I will look around for another. Would the short 16" barrel affect the noise level and how? I'm thinking it might need a larger can to contain the excess gases from the shorter barrel.

Most well designed cans should do the job and 16" isn't out of the ordinary for a .22 at all.

If you can find one of the old parker-hale cans, with the disc-like baffle stack that needed a guide rod to put back together, that'll certainly do the job or any other number of brands that available here.

Check the ammo over the chrono to make sure it is actually running at subsonic speeds, you may be experiencing what are known as "crackers" that go over the sound barrier.

What can you get over there?

Ghubert, I never really researched suppressors prior to mine being made as I was under the impression they were all pretty much the same, seems I was wrong but I am quite happy with this one and I will probably try out a few other brands of ammo before I buy another suppressor. I do not really need my 22 to be quiet but its nice to know it can be if needed.

Barrel length makes a significant difference in the noise level. My suppressed handguns are much noisier than my suppressed rifles even when using the same subsonic ammo and suppressor.

My 16" Savage MKII is a bit louder than my 20" Winchester 06 when used suppressed. I like the shorter 16" barrel as it is more compact even though is is a bit louder.

If your suppressor makes more noise than this I would return it to the manufacturer and get a different one.

Many years ago I read somewhere that a .22lr develops it's highest velocity out of a 16" barrel.Being somewhat much younger at the time I had mine cut(rifle barrel ) and only recently had the suppressor fitted. Suddenly that little rifle had a nice balance once again and it handles very well with the 'extension'. Big difference in noise levels. That unsuppressed chubby barrel sure as hell used to bark quite loud!

Despite what you hear on the internet and see in the movies your can WILL let some of the sound out.

It should sound about like a good pump up style pellet rifle discharging. Quiet, but still audible. The can will have louder 1st round pop, then settle in as the shooting continues. The longer the barrel, the quieter the report will be, and not just from the shooting position either.

I've used a lot of different length barrels from 4" to 24" and finally settled on a 20" length.

With standard stuff sure, but subsonics should be almost entirely silent.

That's with subsonics. With the standard stuff you get the sonic crack along with it.

Used a 1911/.22 conversion, suppressed with subsonic ammunition, the noise of the pistol cycling aside, I'd place the actual sound of the round at about what you hear when you close a refrigerator door normally.

It's interesting to share our experiences, my Walther bolt action has a 20" barrel and a 300 gram alloy can made by Swift Precision Rifles, when I shoot eley subsonics through it I can hear the twang of the firing pin spring, the click of the pin itself and then the thump of the impact.

Perhaps the can you tried wasn't a calibre specific one?

I have owned a Coastal brand .22LR can, I currently own a S-N-S .22LR can with a monolithic baffle design, I also own a Gemtech .223 M4 pirranah can that does about as well as any .22LR can with rimfire cartridges and I've spent a little time behind a Gemtech Outback can and a Ruger 10/22 with an integral suppressor.

ALL of the above cans behave exactly as I described them except the the Ruger 10/22 with the integral suppressor. It was slightly quieter than the others with no 1st round "pop".

One thing to keep in mind when judging these things is the enviroment you shoot them in. If one does his shooting in a wide open field he'll have a different impression than a guy that shoots one near a building or in a bermed in shooting range. The sound is there, you may not hear it because of your inviroment but the sound is definately there.

I use my .22LR can for squirrel patrol around my house. My yard has about a 75 mature hardwoods and is a magnet for squirrels. Around the house and under the tree canopy the sound is much different than when I shoot in an open field.

I have a small sealed can by c3defense called the "clandestine".

my rugar 45/22 that came threaded from the factory, with sub sonic, you hear the slide and fireing pin and a rush of air like a strong bb gun. The same can on a 16 inch 5.7x28 ar with sub sonic, you hear less rush of air same action noise. The 45/22 with cb cap wont cycle the action you hear the fireing pin and bullet strike. I was shooting it in my office ,closed door with was on the other end of the house,never heard a thing.

I am on my third SAK now, they are very good,i can remeber when all you cld hear was the clack of the ruger 10/22 action and the thwop of the hollow point sub impacting the bunny.

We use SAK moderators on CZ452/455 for bunny bashing with the same "click....thud" results.
For around £30 they're unbeatable.

The SAK is by far the best mod you can buy for the money for RF. The quietest mod I ever tested though was an A-Tec CMM4-RF with 2 additional baffle stacks added. It made the thing excessively long for comedy value but was phenominally quiet - no louder than a spud gun and that was from a 12" long barrel pistol(GSG 1911 knock off). My favourite mod is probably the T8, heavy as it is, it keeps going and going

I would actually be interested in a supressed 22LR but for one small detail...

I have an Old Winchester 67A single shot bolt action... out of this rifle's 26" long barrel standrd velocity 22LR ammo from the major mfg's
(Rem, Fed, Win, CCI) come out quietly enough that I can hear the firing pin strike, the actual loudest sound you hear is the spent brass hitting the gound when the bolt is opened briskly.

Supressing this rifle would be a complete and utter waste of time... as my 30year old RWS-45M
air rifle is several times louder.

That all being said a supressor on a 10-22 would be "neat"
