「VSR SPRING
140」
PRODUCT CODE : 649751
This is for VSR-10.The total length is 200mm arround.
This is 13mm diameter & 11mm inner diameter,so please use the 9mm
SP guide & piston has 13mm inner diameter.
We choice the silicon chrome steel to make out this spring cause that is superior to breaking strength.And onemore,this is set the finely pitch.,so we make an adjustment of the power revel.
Our springs are all "perfect"variable pitch.So compressing is light & fast return.
I know some "variable pitch",but that's just connect the some different pitchs.Those are not comfortable cocking & not power we want.l
It means 140% than normal spring power(0.7J).
So it would be 1.2J arround (use 0.2gBB) when with PDI precision cylinder Set HD..
In that case,output level is here.
356 ft/sec , 108 m/ sec ,1.18J
Our Spring may not be correct response.Because our springs are made by craftsman.
Our springs couldn't be made by machines because we need to make with variable pitch(some machines couldn't make that completely) ,so it may happen 10% up & down.
And please check your upgrade parts.If you use HI-SP cylinder kit,it may be down a few output.
