Fits perfectly with ZCI, XT and SHS cylinders. Has a rubber concave pad on the bottom where a silient piston head connects. Double o-rings are around the base for improved air seal. Designed to work with the Silent Piston Head.
** Please note. Although called "silent" these parts do little to dampen the sound of an AEG. It's just a term that has stuck over the years to describe this particular design.
