Installation

The nozzle fits on the tappet plate in place of the original, with the gearbox open, so it is a job for a technician or an experienced player. Before installing it, compare its length with the original nozzle and lubricate the cylinder head nozzle tube it slides on with silicone oil. After fitting, check that BBs feed reliably and that the nozzle seals properly against the hop-up bucking.

Field use

Ergal, a high-strength aluminium alloy, does not deform or wear like the plastic of stock nozzles, and the inner O-ring limits air leaks around the cylinder head nozzle tube. On MP5 replicas, widely used in CQB and indoor games, it is a useful part when servicing the gearbox or upgrading the compression unit.
