Ok, so I'm looking to moving out to more gun friendly states for college and that has me looking at some NFA goodies. I'm looking to buying a suppressed .22, which one would be the most quiet? the high-standard .22 or AWC Amphibian?

Look at the AAC "ELEMENT" This the quietest I've found.

I don't believe High Standard is making suppressed pistols any longer. They were the gun of choice for suppressing back in the days of the OSS (I got to see one in the CIA's lobby.) The Amphibian has been one of the choices of the SEAL teams for a while because they are made to survive corrosion better than blued guns.

You might want to consider a removeable can like the Element that glwbear recommended. You can mount it on a variety of pistols without having to pay a tax stamp on each. Integrally suppressed guns are generally a bit quieter, but I use a detachable can on a Beretta 21 and the sound is about the same as a pellet gun.

The MASTER SERGEANTA is right-on! My background is LE and we've used sub-sonic .22LR ammo and shot out a street light or a parking lot light so that we were not detected. No matter what you buy....... if it is for a .22LR gun it MUST be a "Take a Part" can or you'll have issues with it down the road. 22LR ammo is very dirty and you need to clean your suppressor every 200 to 300 rounds. I use both chemicals and a Ultra-Sonic Cleaner and they clean right up! If you have any other questions send me a PM

Check out the AAC Aviator if you haven't already.

Aviator is discontinued.

The Element is a good can, I like the Outback 2's and Silencerco Sparrow as well.

I've been very impressed with the Innovative Arms Apex can. It's on my list!

Buddy of mine fired one on a .22 handgun and the sound of the bullet hitting the dirt was louder than the pistol.

Huh, I need to pay more attention to dates. I thought it was a newer can, my mistake. Now that I looked at AACs website it isn't there.

If I were buying a new .22 can I would look for three things.

1 All stainless steel construction. This would make the can safe to use in “the dip” as well as in an ultrasonic cleaner.

2 Monocore consturcion. I like monocore since there is no need to line up baffles in the correct orientation or mess with anything like that. Also K baffles (non-monocore) which are the most common these days can be fragile when outside of the can for cleaning.

3 Sound. This would be my lowest priority since nearly all these cans offer outstanding performance. I wouldn’t buy a loud can but if I could have one that was 1 or 2 db louder which offered the features above I would go with that one.

I would probably look at Liberty suppressors if I wanted another .22lr can. Their Kodiak looks amazing. I have not heard it in person but have heard all the other cans people have listed here today and it looks to be right in the mix sound wise. The can has only three parts and indestructible. Also good for use on .22 hornet and .22 magnum.

If you really want to see some sound data get a membership to “Silencer Research” they do independent suppressor testing. Never trust the db numbers a manufacturer gives you.

I would probably think that any modern muzzle can would blow the High Standard HDM out of the water. The AWC Amphibian uses a ported barrel which brings the velocity way down; much slower than is necessary. Also neither of these can be cleaned. When they fill up with carbon and led deposits they get loud and you have to send them back to the manufacturer. I like to do my own maintenance.

There aren't too many cans that are ALL stainless steel. Even the Stainless Sparrow uses a carbon steel tube.

Monocores are neat, although I do believe they tend to have a more aggressive FRP than with K baffles.

If you really want an High Standard, all that stands in your way is Money and patience.

Your getting good advice, remember there's not much resale value, and you are better off to buy what you want once and cry about the price then try to upgrade down the road. As you have to invest in a $200.00 Tax stamp figure that in the pricing and by percentage it makes the difference much smaller. - 22LR have to be cleanable or in 10 bricks you have a boat anchor.

- check out some of the Suppressor Forums - just remember many have their own agenda

Yes I agree it is hard to find a can which is monocore. The only ones I know of is the AAC Prodigy, Thompson Machine Zehyr and Liberty Suppressors Kodiak. Of these only the Liberty Kodiak is stainless. However Elite Iron, SWR and Tactical innovations also make all stainless cans which can be taken apart. There are probably others but this is all I am aware of.

Well according to Silencer Research (which once again is a great resource) the net first round pop on the Liberty Suppressors Kodiak is less than the net first round pop on the AAC element. I say net because the AAC Element is slightly quieter and from what I have read a great can just like everything else AAC makes.

One more thing I would add to this criteria. Any can which is user serviceable must have a removable cap. It could be either the end cap (which is most suppressors) or the primary cap (where the guns barrel screws into it). If I were buying a new can I would get one where both caps (first cap and end cap) can be removed. This will allow you to clean and service absolutely everything. And in my opinion and experience would be the ultimate .22lr suppressor and would last many lifetimes.

The only can that I am aware of which meets every point of my personal criteria is the Liberty Suppressors Kodiak. Your criteria might be different and there are a lot of cans to choose from.

My current can is A Gemtech Vortex 2 (the first can I ever bought). It has been upgraded with stainless K baffles and is now a 100% stainless can and fully user serviceable. It is an excellent performer. I do see an upgrade sometime in the next couple years however. Not performance wise but just serviceability.

Doom,
From what i've researched the bolt closing is the loudest noise, same on both your options.
I like the element, with a pusher tool it can be cleaned. Spectre would be second. 4oz. compared to 8oz.
Sending the barrel back not so much.
Ruger makes a threaded barrel mark 3, or 22/45 or High Standard/Huston will sell a threaded barrel to fit most 102 and up frames.
Good luck...just my .02cents worth...Metrotps

Innovative Arms (linked above) seems to meet DTs requirements. Disassambly is very easy with the supplied tool or a suitable wrench.

You can get the Apex from IA in stainless as well. I believe it's $100 more than the regular one.
