m130/sp130 fps question

[hienjie]

whats the highest possible fps sa m130/sp130 spring (w/o a bore up kit) using .2g bb? i read sa 21st century airsoft that the theoretical fps is around 425 fps but may nag sabi sa akin na kaya much higher.

depende kung gaano katiyaga airsmith mo maghanap ng air leaks. hehehe.
my TM M733 with a USED m130 spring chronoed steady at 440 fps.

There is also the factor of "suwerte na unit" sir. A friend's TM Sig552 chronos at 445fps(bumaba na daw from 450fps) with an SP120 spring and no other upgrades except metal bushings and a tight barrel.

I even did a WELL R5(mp5) once with the usual upgrades of bushings, spring guide with bearing, piston head with bearing, airseal nozzle and new hop packing for a whopping 450fps! Pati ako nagulat. Pero once lang din yun... gaya ng sabi ko- suwerte suwerte lang din.

420-440fps would be a "realistic" goal for an SP130 spring, even much less if it's a shorter barreled AEG- but who knows... you may get lucky.

sirs, how bout the issue of chronometers being used? sabi nila mas kuripot magbigay ang guarder device compared to other devices (intruder, etc.)
jan din nagkakaroon ng issue sa mga competition kasi sa internal gamesite nila pasado ang rate pro pagdating sa tourney, biglang taas ng 15+ fps (assuming the same bb weight ang ginamit ha, that is, .2g bb's)

that's why you have to know what specific chronometer is being used and test your AEG on that chrono before joining the tournament. Kgaya ng nangyari dun sa SM tourney (goldcup chrono for that matter) buti nalang bumaba ang mga chrono ratings eh pano kung tumaas yun hehe

pagyan nangyari. PaTaY!! wala nang participants. ;D
