to cut down or buy again? spiring

[glenny]

Hi Lads nearly done the mk46/ 249 upgrade ..just added a sp110 main spring and it now shoots as 350-365fps...i am really looking for a 330-340 tops would i be best buying a new spring like a sp100 or sp90? or better to cut down my sp110 an dkeep testing until i get the 330ish i want?
thanks glen

i would say to get a 100 spring the last time i cut down a spring by 1 coil my fps fell to less than 300

depends if you want to spend more money. ive cut a coil off before to get what i need saves time and money.
but dont forget it will settle down after use.

i would say 1 coil cut off will take you to 345 and after some use 330-340. it doesnt hurt to try you can still go buy another spring if needed.

called aeg tuning

Re: to cut down or buy again? spiring

if you do go for the cut then do it at the end that is the more tightly coiled as it will give a more level end and wont let the end slip off the side of the spring guide and lock the piston, it also gives the chance to get a smaller reduction in power for fine tuning.i've cut loads off spring's for people who want as close as poss 350fps or 425fps ,personally i cant feel the difference in the field between 330 and 350fps but some people will insist.
