Bore Up?
Bore up Cylinder sets are made to fit all gearboxes just like the regular cylinder sets. However, the cylinder is thinner and made with a bit more precision enabling a bigger air storage in your cylinder. The cylinder head and piston head are of course, a bit bigger as well resulting a higher muzzle velocity and power output.
Recommended for 360 FPS and higher power AEGs
Bore up parts feature larger inner diameters to increase air volume for each shot. Bore up parts must be used with other compatible bore up internal parts.

"Installed in my super custom CYMA M4. I have been considering getting a bore up set for a while and I wasn’t disappointed. The 40FPS increase is pretty impressive considering I was originally using a mix of ZCI and lonex parts that got a great air seal. Overall good price and great quality.

"I just finished installing this on my m16 SPR mod 0 and from what i can tell all of the parts work very well, a couple of things to mention are that the oring that comes in the package for the piston head is a bit small for the cylinder so i would invest in a larger oring for a better air seal. The other thing is, when you are securing the piston head to the piston get a good grip and make the crew as tight as possible without stripping it. I though i had it on tight, but while shimming the gearbox i test fired it and the crew backed out and became loose and the cylinder head started bouncing around in the cylinder.

Pros: So far all the parts are holding up
good fit in the ver.2 gearbox
oring seal tappet plate
Quiets the slamming of the piston head against the cylinder head

Cons: Small oring poor air seal (cheap though so only small con)
screw backed itself out (may have been operator error though)

Overall can't go wrong with this if you have an m4/m16

"I've installed this bore up system on my sr10 kwa , from stock cylinder my fps was running around 450 on an m130 spring , now it shoots around 500 fps with an m130 pdi spring , wow! It's incredible!
