Ask your upgrading question here.....

Here is a new question for you guys:

I recently bought a Classic Army SL8-2 and want to upgrade it to somewhere within the 450 to 500fps range. I'm guessing I will need a better spring and gear set at least, but what other parts should I be looking for?

Also, is there a way to disable full-auto on the fire selector switch?

The most effective way to disable full-auto on a gun using a V3 gearbox is to modify the selector plate so that it cannot pull back the cut-off lever.  If you shave back the notch so it never makes contact with it, the gun will not fire full-auto, even if the selector is put in the full-auto position.  It's a very easy modification to do with a dremel.  

Since your gun uses a mini battery, I highly recommend upgrading to high-torque gears AND high-torque motor, or using a high-output battery, like a LiPo (though in the end it might be more cost effective to just get the gears and motor).  As far as the tension of spring goes, there is no magical way to tell which one will get you the desired results; the compression of air can vary so much from gun to gun.  You might want to test multiple springs, starting with an M130, and make your way up, if you have the resources to do so.  Hope that helps.

Thanks for the info, Batman.

I guess this would be a upgrading compatibility question?  

I recently purchased a m14 repro from gearbox.  It is supposed to be compatible with parts built for the TM M14.

And of course.... I would like to upgrade it!  My intention is to convert it to a high power (yes yes yes in advance....I am aware fps is not everything!) semi auto sniper.

This is my first round of any real big upgrades on my own.  So before I order parts I was hoping to get some feedback on whether the parts I intend to order will be compatible AND if there is some part (spring, pin, etc) that I am not thinking of or should consider getting as well.  Here is the list:

Systema Torque Up gear set

Modify Version 7 Spring Guide with Bearings

I am aware that the m150 spring will wreck havoc on the gun, hence the reason why I listed new gears and a polycarb piston etc.  I think I may be on the right track thus far..... but I could use some advice as I am still a NFG and am more than willing to take any verbal bitch slapping that I may deserve.  :?

Thanks in adavnce!
