RetroArms Delayer Chip is designed for V2, V3 and M249 gearboxes and is installed on the sector gear between the axle and pin. It helps extend the time the hop-up chamber remains open and keeps the tappet plate in the rear position for longer, which can improve BB feeding at high rates of fire or when using weaker magazines. It is designed for axles with a 4 mm diameter.

RetroArms PandoRA 16:1 with 4 mm shafts is a set of CNC steel gears for upgraded AEG builds. All gears are machined from a single piece of steel, and the manufacturer tested them with an M210 spring. The reinforced 4 mm shafts require suitable bearings and shims with a 4 mm inner diameter.
The delayer chip is installed directly on the sector gear between the axle and pin. As the gear rotates, it extends the time during which the tappet plate remains in the rear position. This gives the magazine more time to properly feed a BB into the hop-up chamber. The cam is particularly suitable for setups with a high rate of fire or when dealing with feeding issues caused by weaker magazines. No glue or screws are required for installation.
The cam is designed for V2, V3 and M249 gearboxes with a compatible sector gear.
The delay cam helps extend the time the hop-up chamber remains open, giving the magazine more time to feed a BB.
It is suitable for setups with a high rate of fire, where feeding BBs can be more demanding in terms of timing.
Keeping the tappet plate in the rear position for longer can help with BB feeding issues from weaker magazines.
The cam is installed onto the sector gear and requires no glue or screws.
