KWA SR12 SP150 Drop-in

This is a quick video of the KWA SR12 pulling a Modify SP150. Internals are all stock. Large 9.6v 3600mAh battery from No Limit Airsoft was used. Battery had not been charged for over 4 months.

Did you use the stock gearbox internals with the SP150 spring ?

[hydralovr]

@stefanits1234 Yep.

[Jatodude1]

Yeah, a 150 spring should be shooting in the 550 range. I was curious just how tough of a spring could be put into this gun without putting to much stress on the gearbox and motor and still give a good rate of fire. It comes stock with an M120 and still fires 400+FPS with a .20 gram so that's quite a jump. What gram BB's do you prefer with that spring? Probably a .30 or higher? Good to know I can just drop a stronger spring in. I think I'll go for M140. Any field testing or gearbox wear?

[hydralovr]

@Jatodude1 Yep, I use BB King .30s. I'd like to go heavier, but I don't trust brands like Madbull. lol

I'll open up the gearbox after a while and see if there's anything bad going on.

chrono please? Because I honestly am not sure that a stock KWA could be pulling an SP150 with that ROF.

[hydralovr]

@darthvader1995 I got it chronoed at ASGI and it shot 550 FPS.

[thefoshizle2]

if you swapped in a m150 why even bother putting the yellow sticker back on....unless this is a fake

Im not playing airsoft with you...

[randomperson12494]

Kay Doubloo Aye?

[Spyder93090]

you should change those bearing bushing to steel bushing because bearing bushings are known for breaking around 430 fps and your shooting 550 fps. i would rather buy a pair of steel bushings over a brand new gear set and maybe more

[slice259]

Did you shim the gearbox to use the sp150? Also how has the gearbox held up in the last 8-9 months?

Thanks

[iamhatedbyteachers]

whats the bps

[guythatmadethisvideo]

@hydralovr if it has an m120 and its still shoots like 410 420 then it must have a pretty good air seal

[adeathsmckitten]

How has it held since you put the new spring in?

[darkerik411]

@hydralovr it shoots faster then my gun...
