Allow usage longer inner barrel (more air in cylinder).
A great alternative way to increase FPS output without using a stronger spring.
(Stronger spring means lower ROF (rate of fire) and higher rate of wear and tear.)

Reinforced Bore Up Ball Bearing Silent Piston Head.
Reinforced Bore Up Stainless Cylinder Head.
Reinforced Bore Up Air Seal Nozzle.

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.

"I don't know if it's the bore-up (doubtful) or just the quality of the parts in achieving airseal, but I've installed this in two different gearboxes with no tricks like teflon or permatex, no extra o-rings or anything, and with an AIM torque gearset, a fresh m120 and 407mm 6.03 inner barrel it consistency pulls 420-430 fps where before these gearboxes were struggling to reach 360.

"The Kit is great and has a perfect air seal once it is lubricated. I didn't see much of an FPS gain, only 5-10 fps, but it is much more consistant. Overall it is a really good set and makes it a little quieter as well, this could be a pro or a con.

"Great kit except the air nozzle. It would come loose off my tapet plate when fired. I would give this set a 5 star if it came with a cnc or aluminum air nozzle. Besides the air nozzle the rest of the kit is great!!
