Continuing to provide you, THR denizens, first looks at new stuff, I give you..

The Arctic Silent Ruger..

Carbon Fiber can, velocity loss less than 100 fps with Hi Vel Ammo, and very very quiet....sounds like a cap gun going off...

Who made it?

[762x51]

NEAT! Too bad I live in this stupid state. :banghead:

[Ledbetter]

What kind of stock? Trigger work, accurizing, bedding?

Beauty, beauty, beauty. But, umm, what makes it Arctic?:scrutiny:

Great looking little carbeen.

[4v50 Gary]

Artic-rizing the Ruger. How about a cheap plastic trigger and trigger guard so your hands won't stick to the trigger? :P

[jYm]

whats the price?

[Wildalaska]

What kind of stock? Trigger work, accurizing, bedding?

Its just a coated wood stock that we bedded in. So far at 20 feet its grouping nicely. Ddidnt bother putting Power parts in for the trigger.

But, umm, what makes it Arctic

We shot it out in the snow :) Its then Arctic-rized :)

whats the price?

Tentatively $699 retail, plus of course the transfer tax.

[Marko Kloos]

Looks like fun. Add a FA sear, and I'd be willing to drop the money on it. (Two tax stamps...ouch. Isn't the one for a can an AOW stamp? That wouldn't be too bad.)

[Ledbetter]

Godfrey Daniels!! Winter is nearly over and I plumb forgeot to arctic-ize my rifles. :cuss:

[Wildalaska]

(Two tax stamps...ouch. Isn't the one for a can an AOW stamp? That wouldn't be too bad.)

Nope its $200.......WildheywannaraisemoneyunbanmachinegunsAlaska

The Arctic Silent Ruger..
Wouldn't it be great if "arctic" caught on and surpassed the juggernaut adjective that "tactical" has become?

Great little rifle, how does the can sound compared to steel and aluminium?

Seems to be as quiet as the Gemtech Aluminum one for a 22...

If the velocity loss is less than 100fps with hi-vel ammunition, how can you describe it's performance as "very, very quiet"? I have a few suppressed .22s at work and with the muzzle can and hi-vel ammo it is almost as loud as the unsuppressed rifle. The supersonic crack caused by the bullet is about as loud as the normal muzzle blast. The integral can has to drop about 400 fps with the hi-vel loads to keep them below the speed of sound.

[gk1]

Hi-velocity .22LR ammo is ~1250 fps at 70 degrees. In Alaska, after subtracting 100 fps, I doubt they're supersonic. You're thinking hyper-velocity, I believe.

Exactly what I was thinking last night when i was demoing it while holding the bolt closed (which makes it even quieter)

We were using Win Wildcat ammo. Out of a regular 10-22, it was about 1170fps. Out of the suppressed gun, it was 1083. We are gonna try Stingers to see what they sound like.

We also did some of those CB longs, they wont feed but its like a sneeze.

Our biggest concern is accu5racy though. Right now at 20 feet all rounds are touching.

We have a very short expansion chamber in this one. We are gonna legnthen it on the next one to see what it sounds like.

CCI makes subsonic .22 LR ammo.

All gun laws are stupid, but making suppressors "Class 3" like a machine gun is particularly stupid. Even anti-gun countries like Germany encourage suppressors to cut down on noise pollution and hearing loss.

I'd sure like a suppressed .22 rifle and handgun so I could target practice without muffs.

Back in the shop again this morning and my notes show me 1302 fps average from my 10/22 (from back when I had access to a working chronograph). I realize now that my match barrel, with a tight chamber, gives higher velocity than the loose, sloppy chambers of factory barrels. I am guessing my rifle gives about a 75 fps boost over the factory gun, also taking into account the temp and atmospheric conditions the speed of sound varies a bit. I think I was assuming (yes, dangerous) that at about 30 degrees F the speed of sound would be about 1080 (lower temp and the SOS would be lower). In my rifle the round would still be around 1200 with a 100fps loss and that is still, certainly, supersonic (at least until it hits 130+ degrees or so). At least now I understand where my info could have been skewed a bit.

WildAlaska, are you sure of the accuracy of your chrony? What was the ambient temperature when you were testing? If it was 30 degrees you were right about the speed of sound, if it was colder you could have been over the SOS (1050 at 0 deg F) unless the chrony you used was off a bit. My understanding is that the sound pressure level climbs rapidly as the projectile climbs to and passes through the speed of sound. Starting about 50 fps below and ending about 50 fps above the speed of sound that is.

I am not trying to be real picky, we are concidering getting a manufacturing license with SOT and I have been doing quite a bit of research in these matters, any of your experience would help me some.

[Wildalaska]

Hi Jake we were shooting indoors in the shop...that itself could have caused the chrony to go off due to the lighting...it was about 70F (hey if its cold outside!)

Had a Supressor dealer come in to listen, he said its at least as quiet as the Gemtechs..

My concern is the carbon fiber tube..its strong but I am wondering about the effect of the gas over and over on it..we are gonna make the aluminum end caps and baffles a little extende to act like a liner over the gas vents to prevent the gas eating away at the carbon fiber..I am trying to find out right now the gas resistence of the tubes.

Also, the expansion chamber can muffle the sound of the shock wave if the bullet goes supersonic in it...I think

I tried some Aguila sniper 22...10 feet away it sounds like a pencil breaking...

BTW If you think you are gonna make money with a SOT....:neener: I bet it will take us two years just to recoup the cost of the license.. :D

[ShaiVong]

Do you really want it less than 100fps though? Couldnt you increase the velocity and extend the range while still staying subsonic?

[Jake 98c/11b]

WA, I don't think it much matters if the expansion chamber can muffle the the sound of the shockwave, that shockwave will follow the projectile downrange as long as the bullet is supersonic. I like your idea to protect the carbon fiber tube from the erosive effects of the combustion gasses and unburnt particles. How well does the carbon fiber hold up under a sandblaster with fine media? That might tell you how well it will hold up as a suppressor tube. Reminds me of the Vaime Co suppressor for .22 rimfire, both the tube and baffles were plastic but the expansion chamber and first baffle were (I think) aluminum for the same reason. The carbon fiber may also reduce the noise of the combustion gasses rapidly filling the inside of the can, sort of like the sound of an aluminum bat makes with a good hit. I heard that quite clearly with a can on a Jati Matic subgun a few years back. Probably not much of an issue since the internals should dampen that noise just as well (I think), it was noticable in the Jati because it was mostly empty space.

[Wildalaska]

Hmm good point about the sandblasting...I think thats the reason we dont see many suppressors for centerfire cartridges...

My problem with the velocity issue is either the chrony is lying or my ears are bad and cant hear the crack...I really need a db meter and to shoot it outside...
