parang baliktad nga?

basic upgrade po yun sp130 sir kaya ganon result, Try mo sir all stock jg m4a1 aeg lagyan mo sp130 spring tingnan mo kung ano result. Nun gnawa namin yan using xcortech chrono 458fps result nya spring lang pinalitan. Un case ng pdi 190 spring some internal parts are upgraded too, like cylinder, spring guide, barrel, hop rubber, ASN, etc. hindi na po bago yan ganyan result sa pdi 190 spring, like dun sa other thread kung hindi ako nagkakamali nasa 500 fps pa na achive ni sir alencore sa pdi190. Try mo review ito thread http://www.filairsoft.com/forum/showthread.php?t=37230 BTW sir ano po ang current fps reading nyo sa sp130 nyo at ano po chrono ginamit?

ok... Mga gurus correct me if i'm wrong. . .

PDI 190's rating is in the middle of SP120 and SP130.
Tama po ba?

@Neodarkangel- Sir Let's go back to your question... Kaya ba ng JG Black Gearbox ang SP130? opo kaya po.
-1 YEAR mahigit ko na gamit (my AEG is a JG M733)
-upgrades are the following
*Spring SP130
*CA cylinder head (binigay lang sa akin itatapon na ng orig na may ari)
*CA Airseal nozzle
*CA Silicone Pisto Head w/bearing
*Spring Guide with bearing

My gun clocks at 460 FPS using ICS 0.20bbs

STOCK CYLINDER
STOCK PISTON BODY
Yes sir! I'm emphasizing it very well it's still using STOCK PISTON BODY for over 1 YEAR already.

I'm quite sure majority of the people reading this thread would not agree. Anyways. . . JG Blackgearbox can withstand SP130.

[jabron]

wow ayos to ah, konti lng pala magagastos ko kung sakaling gusto kong ma reach ung 450fps

[ÖDIEHARDÖ]

just sharing my experience on my AnK CQBR, 450FPS after doing some tweaking

Internals:
TU TB 363
type ZERO Cylinder
stock Cylinder Head
stock ASN
spring guide w/bearing - stock
piston head with bearing - SRC
stock spring
stock hop-up rubber

mods:
NHM hop-up nub
teflon on hop-up
teflon on cylinder head
shaved the tappet plate (front portion that holds the ASN to maximize forward stroke)

Thanks to FAS and to the mod masters, dami kong natutunan na mods to improve my AEG with minimal expense.

I agree JG gearbox can withstand the SP 130. Howevewr, due to the factor of wear and tear, eventually it will give in.

To answer the query of the thread starter. If your target is 450FPS, why not use PDI 190? Your S-system has 363mm lenght barrel same as in my M4 SR16. I use PDI 190 on my SR16 that clocks 460 average before it settles to 430FPS. I only changed my inner barrel into 6.02mm diameter or better groupings and to make it on the 450FPS average. I only suggest to use a less stiff spring since you are only using stock gearbox.
