SpudFiles

They do, they decrease the velocity of the gases exiting the muzzle, and reduce the uncorking effect. So they do have an effect.

JSR, you said you were getting paid well for this.

They certainly do - the last two I illustrated are for maxed out versions of this monster. Without the suppressor they literally sound like a firearm, but with the suppressor fitted you mostly hear the hammer hitting the valve, the difference is impressive.

Considering material costs are around 5 to 10 euros per unit, and I can put one together in a couple of hours, I would say it's a fair price. Had I been making metal internals the manufacturing time would have risen considerably to the extent that I could not sell them for an affordable price.

Here's a massive one I made for one of these in 9mm:



I made it similar to the Shinsung suppressors, but it slips over the existing shroud instead of being threaded and the first baffle area is perforated to allow air to expand into a large 70mm (around 2.75") diameter tube I slipped over. The eccentric design allows a large area without interfering with the scope line of sight.

3D rendering is the original idea, a little different from what I actually made.

Thought I'd go a bit upmarket and give carbon fibre a go, tubing is quite pricey but the costs are happily passed on to the customer

This one is also for an Evanix beast, it slips over the existing shroud and attaches via the 1/2" UNF male thread on the end of the shroud.

This stuff is getting pretty sexy

Yes indeed even if I say so myself. Wasn't happy with the endcap finish so I refinished them, now it's looking great. I ordered some black delrin so that for future models I can avoid painting altogether.

Here it is next to my Daystate Airstream CF silencer for comparison:

Very impressive Jack to say the least. Pretty darn sexy as well!!! :flower:

Did I miss something? Are you using packing in between the sections? I over heard some one say "steel wool works fairly well"???

I'm putting a perforated ring between every baffle to space them.

Steel wool works for combustions and hybrids because it absorbs heat, and cooling the gasses lowers the pressure, which means less noise. For pneumatics it would not really make a difference.

I suggest watching this video if you're interested in the threory

Some of you might remember the rather primitive suppressor I had made for my Anics A3000 "Skif" CO₂ pistol using lego blocks as baffle separators:



I decided to revisit the idea taking advantage of my improved fabrication facilities, herewith the result. Chopped off part of the plastic barrel sheath and epoxied on a brass sheath with a male 1/2" NF20 thread on the end, then made a 5" long 1" dia carbon fibre suppressor to fit, much smarter now

hehe nice! how effective is it?

No idea, no CO₂ in stock

Maybe I should make one ofthese.

You piston seal is next in the machining queue by the way, will have a crack at it tomorrow

How's the Skif mate? Very tempted by one, but I want at least 450fps. And obviously, how's the accuracy?

Great stuff JSR!

I actually brought one recently, i have the 'silenced' version with the extended barrel.

One downside is the trigger, it's a bloody heavy pull. I'm guessing the magazine rotation design is to blame ....

First of all, this says "MADE IN RUSSIA WITH PRIDE AND QUALITY" on the box so I am a little biased in its favour As far as CO₂ pistols go, it's one of the more powerful ones available and certainly few can match its 28 shot magazine capacity, if I remember well it does 3 ft/lbs with medium weight lead pellets. Accuracy is "good enough", it's obviously not a target pistol but I can land all my shots on a tin can a 10 metres very easily.

As daniel mentioned, the trigger is positively agricultural on double action because it not only cocks the hammer (which is also the barrel, nutty Russians ) but also has to rotate the magazine "conveyor belt", but on single action it is very acceptable.

It's also very hungry for gas, I get about 2 magazines' worth before it starts to run out, and fast firing tends to aggravate consumption.

The magazine is also a bit sticky, in the sense that it doesn't exactly drop out when you push down on the lever.

On the whole, I love it though, great little toy
