I got to thinking last night and realized something about the on/off of the mag. This is kina long and tell me if your confused but it makes sense to me.
At this point a level 10 classic or RT (I think this will work on an RT, not positive) valve is pretty nice, can't chop, recharges plenty fast and has plenty of potential for high rates of fire as well as being very reliable. There is however, one last thing to improve. I'm talking about the trigger here. Now, I'm not firmilar enough with the RT to say if this will apply to it also but in the classic mag, it'd be a nice improvement.
The problem lies in the trigger pull. Most mag's have a very stiff and snappy trigger pull. Like everything, there is a reason for this. It lies in the on/off pin. This has nothing to do with flow but just a small bit of metal that could be milled off and make a huge difference in the trigger.
In a normal mag, the 400+ psi comes in from the reg and pushes down the on/off. This inturn pushes the sear down and locks the bolt in place. It is this pressure that is causing the stiffness of the trigger.
Now think of the on/off pin, just a cylinder of metal with a bit taken off at the bottom so you know which side goes up. It is the on under engineered peice in the system. Next lets think of the pin in the off position, sealed against the o ring. Now let's gas the gun up, the incoming 400+ psi pushes directly down on the pin. Think of this X amount of force on the pin. Now what if we were to mill down part of the pin about 1/4" from where it seals and make the pin very thin, say 1/8" and making the rest of the seals small enough to accomodate this.
Now we have the gas working against it's self. It's pushing down on the top of the pin and at the same time pushing up at part we milled down. Think of it like this
___ <----- gas pushes down here
I I
l <------- and up down there
l
Now that we have the gas working against it's self, the trigger pull will be much lighter and accomplish the same thing the stock pin does.
This is the basic idea behind the galactic on/off pin, factually the only peice worth buying for the automag valve because of this flaw, the last in the automag.
