View Full Version : ? on the valve spring
06-10-2007, 01:23 PM
if i get a lighter valve spring
would that increase the amount of air and thus make my gun recock more efficiently when firing on full auto
i know getting the Halo would be the best but i am just wondering if a valve spring
changing both valve and striker springs
they are priced a little cheaper then the halo
also \has anyone actually trimed there valve spring a little to make it weaker

It may just be that no one makes valve springs specifically for the MR series markers - ;)

The only way that I know of changing your spring rate for the valve spring, is having a custom perch made for you. I turned one down for myself so that it sits flush with the front of the body(so i could use an m-16 fore grip/cover) and not have it look stupid(with out the stock shroud). Its easier to increase the spring rate this way(make the spring perch longer so the spring is compressed more) than it is to decrease it(too short of a perch and you'll have problems with keeping the spring seated and the valve shut).
If you don't have a lathe, then your only other option is finding a supply outlet near you that has a variety of springs and trying out different ones. I don't recomed cutting any spring unless you already have a replacement for it.

I actually made a weaker valve spring out of an old Brass Eagle Raptor main spring. The inner diamater of that spring fits perfectly on the valve seal (err...that white thing that screws into the valve stem)
In answer to your question, a weaker valve spring will allow the valve to stay open longer which will let more air through. Will this make your gun more efficient? I don't know.
Mine is more efficient because I have my pressure regulated down to 500 psi. I let my gun run on full auto (without paintballs) untill it ran out of air on a 20 oz tank. I got around 1200 shots just from dry firing the thing. I
