Description
The CYMA G39 (Standard) Hop-Up is a hop-up unit for the G39 platform, produced in plastic and supplied in the standard specification. It carries the manufacturer reference HY112. As an internal part, it is fitted inside the rifle, where the hop-up sits in the BB’s path between magazine and barrel.
Being a moulded plastic component, it provides a direct way to replace a worn, damaged or missing hop-up in a G39 build, or to keep a spare on the bench for servicing. Fitting is workshop work: the unit is reached with the rifle stripped down, so it suits someone comfortable working on their own internals or a technician handling the job.
It is listed as an internal part for the G39, and the HY112 reference makes it straightforward to check that the unit matches the one being replaced.
