Very High Pressure Automag?

Questiuon RobADG

Are you by chance the same FRG/SWARM Rob?

You also got to remenber that was about six years ago when these gun were areound, and information about them was very scrace.

[Muzikman]

Yeah, I dunno, I have been shooting a Mag since 93, so I was around 6 years ago. Never heard of one, but I also never knew AGD made an expansion chamber for ols Sheridan guns either Learn something new every day. Now, I need to find me one of these valves!

[Flow_Tech]

I have never heard of such a beast. Interesting if they did exist.

ive never heard of it eaither.

[Lohman446]

INteresting concept, would be neat if we could get a drop in modification made now for it, I would love to state "ultra high pressure, I need 1000PSI input"... and... WE COULD MARKET A MAG EFFICIENCY MOD... just shut up and noone tell those into hype the downside of the trade off.

[the123]

I have a couple. The mod is very simple. Remove the power tube to expose the air chamber, instert spacer and then re-assemble. The velocity then needed to be turned up.
Why this isn't a feasable upgrade for current AGD valves is the advent of level 10. By the nature of level 10 you need to turn the velocity up. Same with the Hyper mod. Combining these results in the reg piston's safety blowing off before you can finely tune level 10 with at least a middle spring. I've tried and never got a reliable working result. A reg piston with a HIGHER blowoff pressure would be an easy fix. Or perhaps a slightly smaller spacer. Level 7 Mags it seems to work ok, with a slight increase in efficiency.

Give me a price, I want one for my level seven devilmag.. PLEASE

I'm serious I want one.. I need to be gone for the afternoon but if you are interested in selling let me know

Brian! Sell me one! Come on, we are old buds!

He's going to collect it .. I'm going to use it... please please... hey ROGUE or anyone.. I have an idea for a new upgrade PLEASE

Hehe.. just kidding Muzik, your collection rules.

Here's one:

yea, id like to see how you are going to use it, as the powertubes are not removeable in current valve designs.

Hyper Mag

The Hypermag setup we used to run was small lines going to the valve with around 900-1000 going to the AIR. I also thouht that Airgun was making the smaller ait chambers for FRG, the ones selling the gun.
On a side note, my RT one of the old ones had an enlagred air chamber stock to reduce the pressure in the firing chamber. It had some additional holes drilled into the chamber. The side effect was the reduced efficency (900 shots on a 68 4K tank). One of the next improvements to the gun was reducing the chamber size to increae the efficency of the gun.

.

The ablove isa great way to do this - but is there a lower tech way of doinf it? Wouldn't it be possible to just drill through the side of the valve and tap the hole. Then put a large set screw in the hole. Turn the set screw in to decrease chamber volume and turn it out to increase.

[AGD]

Yes its true but we didnt make them Dennis did as stated. He wanted to get back to the old efficiency because he didnt have problems breaking paint and thought it shot better.

If you want to simulate the effect get a length of stout urethane cord and stuff in down the power tube so it spirals into the chamber like a spring. That will take up space but you will likely have problems with the piston venting.

AGD Also made a valve in 1990 for PMI 1 DF's. It was supposed to increase efficiency I believe.

I knew that. It's just a new sheridan valve. I actually have one here.
