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.
