Type A: Type A Cylinders are full volume cylinders that use all the amount of air in the cylinder to propel a BB forward. Works best with 363mm to 550mm inner barrel lengths as that amount of air will be needed to push bbs farther in Rifle and DMR-style builds.
Type B: Type B Cylinders are ported cylinders that are cut before the edge a cylinder to utilize a portion of the full amount of air volume. Works best with 318mm to 510mm inner barrel lengths for Carbine-like builds.
Type C: Type C Cylinders are ported cylinders that have inset cuts a third of the way into a cylinder to allow more air blow-off. Works best with 280mm to 430mm inner barrel lengths for PDW and CQB builds.
