Experienced Airsofters Only, Check Me On This One...
Hey Guys,
I am going to upgrade my ICS PCR-4 ( M16 A3 )
this is my plan...
Guarder SP-120 Spring
Guarder Spring Guide with Bearing for Ver. 2
Guarder Steel Bushings with Dual Oil Channel
Guarder Polycarbonate piston
I figure this would get me to 380-400fps ... What do you think? Suggestions? Recommendations? Thanks
-DD
