POM AEG DCI GUNS PISTON HEAD (DCI116002)

Side air ventilation system
Through holes in the sides of the piston head prevent o-ring over-expansion and provide consistent speed in all grease conditions.
It also reduces negative pressure during piston extraction, contributing to cycle customization and high efficiency!
specially treated with a dynamic friction coefficient less than 1/5 of that of conventional NBR (nitrile rubber) O-rings. Non-adhesion to almost all metals prevents the O-ring from sticking to the cylinder. Ideal for high rate of fire and long duration.
AOE adjustment spacers can be added without modification.
Most screws can be purchased when you want to add more than 2 adjusters. The AOE adjustment spacer is not included.
The piston head has a slightly smaller diameter and a round shape at the front and rear of the piston head to prevent damage to the inner wall when the piston unexpectedly moves into the cylinder.
A thrust bearing is used in the spring catch area to prevent spring slippage and ensure smooth operation.
