Lowering the Trigger Pull on a Classic Valve

[ascent]

Hey everyone.

I have been breathing new life into my Mag classic lately and was wondering about decreasing my trigger pull weight.

Now, i've done my research and seen that a ULE will not work well, if at all, and what I should be looking for is an RT On/Off..

Problem is that I cant find one new anywhere; which leads to my question - I can get an Emag on/off new from tunamart.

Emag/mag on/off assy. Comes complete with pin(.712) and quad oring


Will it work? I just have no idea...

The only difference between and EMag on/off and an RTPro on/off is the length of the pin and the O-rings that come with it. Contact Tuna and let him know that you need a standard RT Pro on/off with a 7.50 pin and he will set you up.

Will do, thanks!

I found it after a little more digging.

Now i have been reading all day about how a ULE kit will work, but increases the chance of short stroking. Is a ULE trigger pull kit a really bad idea.... or...? Don't mind having to pull it and release it all the way for every cycle like an autococker, but I also want to keep it beginner friendly as it is mainly a loaner gun.

Has anyone tried a ULE kit with a .750 rt pro pin?

Edit: maybe scratch the .750 pin idea.... Now i'm reading that it works fine in a lvl 10 classic valve with a f-ton of shims in it. is there any truth to this?

I have RT on/offs in several Classic valves and they work fine. Should be ok for a loaner marker, but honestly, I am the KISS type for backup/loaners. Keep it as simple as possible.

The classic valve regulates the air pressure at the top of the on-off pin down to working pressure which really reduces the return force on the top of the smaller ULT pin. If you have any restrictions or friction areas in your mechanical mechanism, it will affect the return because that friction becomes a larger percentage of the total force requirement. You can control your finger to reduce its effect on each shot, but you also need to make sure the actual physical sear mechanism is in perfect condition and not rubbing anywhere.

The ULT won't accept a normal rt pro pin. They only accept the ULT pins due to the ULT having a different pin diameter.

Using a lot of shims in the ULT in the classic can help by reducing the distance that the pin needs to travel into the tip oring before the sear can release the bolt. This reduces some of the friction effect caused by the oring. However, it doesn't guarrantee results. Friction comes from many places. Chamber operating pressure also has an effect on the operation. The barrel you are using affects the operating pressure. Unfortuately, I think the less efficient your setup, the better a ULT will work in a classic valve. That is because the regulated air pressure is higher for an inefficient setup than for an efficient one.
