Spectre II

 

You know, an Amphibian is about the only one I have seen that is pretty quiet on the first round, but that doesn't really help you out. Other than that, I have always had better first round luck with a dirty or wet can.

 

The first round kinda charges the can so to speak.

If you want a silent first shot you need what is called a wet can. You use wire pulling lube (clear glide) and the first shot is good to go.

Might also try a can of dust-off. It's just CO2 in a convenient form factor for blowing dust off computer motherboards, grit out of keyboards, etc. Stick the little tube down into the guts of the can & give a good long squirt of CO2. With little or no free O2 in the 1st chamber of the suppressor, the hot expanding gases from behind the bullet shouldn't be able to ignite in the enclosed chamber [which is what causes the FRP.]

 

Spectre II with subsonic ammo.

 

I read the Liberty Kodiak has no frp and very little back pressure. Its a good long 6.5" I recall. The Sparrow is only 5" and Spectre is 6" for comparison.

 

I have a Kodiak TL and there is some FRP. Not as noticeable as the Sparrow on a pistol, but it there.

K-baffles give the least FRP, and monocores generally have more FRP.

 

Is the Kodiak as quiet as the Sparrow and Spectre after a few shots? Is it best on a pistol or rifle or a good all around?

 

The Kodiak is good on about everything, but as noted is long. It isn't nearly as easy to clean as the Sparrow SS or Spectre II, so I mainly use the TL on a S&W41 now.

I'd say the Spectre II is solidly more quiet on a pisol, and it doesn't matter on a rifle. The main advantage of the Sparrow is it is so easy to clean. A nickel in vice grips is the perfect tool to clean the shells, costs a nickel, and you can get your money back.

Some say the Spectre II is as easy to clean as the Sparrow. I have both but have only cleaned the Spectre once so far.

All are good cans and you won't go wrong with any. The Kodiak probably has the least back pressure of all of them.

 

I know this is an old thread, but the AAC Element 2 has not been mentioned. From personal experience I can say that it exhibits no discernible FRP on either of the two hosts (Ruger 22/45 and a registered AR lower with a 4.5" 22lr upper) my buddy shoots his on. This with several types of bulk pack 22 ammo. My Spectre II (which HAS been mentioned) has no FRP on my similar AR/SBR, my TacSol 2211 conversion, or my Savage TR.

 

I haven't experienced this with my Sparrow.
On another forum, http://www.thehighroad.org/archive/index.php/t-646268.html
"I was told that spraying it out with canned air (keyboard cleaner) then putting stickers over the holes (til used) would get and keep the oxygen that causes FRP out just fine."

 

automatic system

My AAC "Pilot" has noticeable first round pop (FRP).
Not that it matters, usually. I'm just trying to shoot without ear protection, outdoors, without bothering the neighbors.
But if being really quiet were critical to my mission, I'd want to eliminate that FRP.

I may try a shot of "canned air" (not really air, nor CO2, but rather some other basically non-flammable inert gas).

What would be really cool would be to have a silencer with an outer sleeve that's actually a pressure vessel for some such inert, no-oxygen gas, which you could recharge yourself from a big tank that you'd get at some industrial gas supply place.
When you need to purge the oxygen-containing air from your silencer, just press a momentary contact button on the can itself, and the outer sleeve sends a jet stream of the gas into the silencer, displacing the air. Just hold that button for a second or two before your first shot, and you're good.

If you end up not firing your gun for a minute or two, and you need your next shot to be extra quiet again, give it another button-push.

I used to have a full size (Chevy C10) pickup truck whose rear bumper was actually a rectangular air tank. I'd pump it up to 120 lbs. at a truck stop, and I could fill a bunch of flat tires with it.

 

This might be worth checking out. The sparrow has some noticable FRP but it's really not that bad.

 

My mask has none. My sparrow has significant frp with pistols only. I really don't care about frp though and if we really need to get quiet then we spritz the can and then they are equally quiet in the first round

 

The Tac-sol Axiom suppressor has very little frp when shot dry.

 

I second Bullpup-one no frp

 

AAC Element 2
Dead Air Mask 22
Rugged Oculus
Liberty Regulator

 

I have to second the AAC Element 2. This can is super quiet with no FRP.

 

I'm deciding between the Dead Air Mask and the AAC Element 2 - leaning toward the Element 2 because of the much lighter weight (will be using on a Browning Buck Mark pistol).

How do you like yours? Would you buy again? And how is cleaning it?

 

Good to know - thanks for the info.

 

Foam

I saw a new product on one of the TV gun-related shows (on Sportsman channel?) showing a new specially-designed aerosol foam product that you squirt into the front of the suppressor. It supposedly holds up for hours in case you need to walk around a while before shooting. Eliminates FRP. Sorry but I don't remember the name, maybe someone else here knows more about it?

 

FRP with sub sonic is over rated and over done.
I don’t hear a FRP with my sparrow and an FRP is the oxygen being burned out of the can.

Do what was suggested earlier and get a can of dust off to blow out all the combustible air in the can.

In respect to rimfire suppressors.......the only can that I have come across that has no noticeable first round pop with the .17 HMR cartridge is the Bowers USS 22 can, which makes is super effective with .22 LR. The Bowers can is built "Old School" with respect to baffle design so it requires a little more attention to cleaning & maintenance than some of the newer designs but still is a very respectable unit for sound suppression. The USS is about 1.125" longer than the majority of its competitors and that is what causes it to be so quiet and of course Bowers has some great customer support.
I am very happy with the can I purchased but if I had to do it again, I think I would have purchased the USS.

Hope this helps.

 

Just an FYI trick...
If the action of the host firearm can be opened just enough to exhale some of your breath inside the chamber and down the barrel and into the can....then chamber a round and fire it, no frp. Not all of us wish to carry spray cans of stuff around when actually squirrel hunting. Your own breath can eliminate frp in most systems where you can exhale into them.

Been doing this for decades.
