Cylinder Hole Location vs Barrel Length Guide Chart
Cylinder holes and barrel lengths, and how they relate

All posted Cylinder Lengths are Manufacturers recomendations. These cylinder lengths are designed as a guideline only. Changes in cylinder type may result in loss or gain of fps and or increase or decrease in rate of fire.

These are only recommended set ups, we have been experimenting with full capacity cylinders on all manufacturer models and have found slight variations at this point in fps. - TEAM 21CA.
