Will the stock internals be able to handle a M130 spring??? How about a M150???

What would happen if I installed a type-0 cylinder with the stock inner barrel???

BTW, should I use a bore-up cylinder or a non-bore-up cylinder??? What's the difference???

M130 = yes but the gears and piston body  will wear faster.
M150? LOL!

There is no doubt that the KWA gearbox can handle an m150 tho...

Type O with not very fast ROF should be okay with the stock barrel.

There is very little diff with a bore up kit an a non bore up kit.. some say it adds 15- 20 fps (m150 up) ... I think its just marketing strategy ehehe! (how can you make something bigger without affecting the other parts it goes into? Wouldnt you need a larger diam gearbox to accomodate the "larger" cylinder?)

As far as I know LE version of KWA 4A1 is installed with M150.  However, being use in a LE training.  They only shoot in Semi most of the time.   KWA M16 will have a M130 spring in the US market.


As for Bore up kit, it's believe only activate when using spring that's about m120 and the piston o-ring must be warmed up before it adds the extra fps.

No idea.... until I get one to chrono it.  however, on my M4 to M16 conversion I dropped a PHX m140 in my gearbox and it's 496-500 fps on .20g.  I couldn't even do that on my old CA with a Systema m150 drop in.

Right now I need some .28g bbs.

LE version??? Where can you find that???

KWA M16??? Doesn't that come out summer '08??? The website doesn't even have a picture of it yet. I wonder what the price tag on that one would be??? And if their going to sell a gearbox of the M16, can that be a drop-in replacement for the tactical??? I wonder????

what is a PHX m140? is that the spring? aside from that, did you change anything else in the m4?

thanks.

PHX is a brand.  M140 is a spring.

I also install type 0 cylinder.  and I plan to change the piston head to Guarder ported piston head.
