Not quite sure of the velocity yet.I haven't been to a chrono,I would assume it is well under the 230 fps. mark.

Good job, you've got the M79 look and function, simple valve, everything's self contained, excellent! All it would need for ultimate perfection is a cartridge ejector ;)

My face plus your gun= stupid grin, i think i may need a grinasectomy!
I would love to own such a device, i imagine the feeling of cocking this beauty is nearly as good as firing it.
Great work MrGoathunter. :salute:

That is simply f***ing awesome! amazing work goat!

How much flow does that specific pressure washer handle have? I am a little confused as to how you connected the source to the pressure handle, I thought those had an input fitting at the bottom?

Good grief that looks nice.

3/5 of a cubic inch chamber volume :o Is that the volume of the washer handle?

Yes it would.But I'll tell you I'm just not up to that sort of manufacturing yet.

How much flow does that specific pressure washer handle have? I am a little confused as to how you connected the source to the pressure handle, I thought those had an input fitting at the bottom?

I'm not quite sure the flow,I picked the valve because it had the input on the front and standard 3/8" threads.All the others had specialized threads and inputs on the bottom,which severely restricted my choices.The Co2 tank is connected via the high pressure hose.Because the valve input had 3/8" threads I could reduce it down to 1/4" and use a highpressure fitting to connect the hose, valve, and ASA.



3/5 of a cubic inch chamber volume Surprised Is that the volume of the washer handle?


No, the volume of the hose.The valve piston(if you can call it that) is directly after the input threads,so the valve does have a little volume but not enough that I was going to worry about calculating :wink:
All said the volume of the chamber is still less than 1".

I guess I might as well say it too.

Holy F*ckin Sh*t


But really, this is one of the best looking pneumatics on this site. You could probably convince someone it's a real grenade launcher if you wanted to.

The only thing I would change is replacing the hose with copper tubing (no snags), and give it some leaf-stencil camo if you feel it would give an advantage.
