"Guarder main springs are the best in the game imho. my sp85 puts me at .95j and my sp110 right at 1.54j. less than 1fps deviation. very very consistent.

"The SP-150 spring is FANTASTIC for the AS01/AS02 Strikers! Better than the Irregular pitch springs I've had. Every airsoft website is constantly out of Striker SP-500/550/600 upgrade springs and this is comparable to the SP-500 upgrade. I'm slinging .40g with ease using the Guarder SP-150.

HIGHLY RECOMMEND FOR ARES/ELITE FORCE STRIKER BUILDS
