For overseas only
This is for VSR-10.The total length is 200mm arround.
This is the same size as Normal spring.11mm diameter & 8mm inner diameter,so please use the 7mm SP guide & piston has 11mm inner diameter.

Material
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.

Variable pitch
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.

What's the 310 ?
It means 310% than normal spring power(0.7J).
So it would be 2.28J arround(use 0.2gBB) when with PDI precision cylinder,taper cylinder head+ ,s-piston.,7mmSP guide.
In that case,output level is here.
495.5 ft/sec , 151 m/ sec , 2.28J

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.
