All Bolt action rifle
「SS 5000」
PRODUCT CODE : 649263
This is the one of the most power spring series.
We manufactured SS-Springs for Super 9 pro,now these series are known
to everyone as the most power spring for all bolt action rifle.Indeed,APS-2,Type96,M40XB
& VSR-10 are OK.
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
This spring is over the air soft level.So your gun will be full tune.Maybe normal parts dosen't stand for.Please use custome parts,like a using the steel or Duralmin or iron.
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.
