【T-N.T.】M.A.V. system / Steel piston head
●Silver one is aluminum piston head (10g), Black one is steel weighted piston head (30g), suitable for heavier BBs when low initial velocity setting.
●A screw hole is designed in the middle of the piston head, which can be used with the "air brake" on the market.
※It is recommended to put some screw glue before locking the piston body to strengthen the fixation to avoid loosening in the future.
