Retro Arms POM Sector Delay Clip for 4 mm Gears

The Retro Arms POM Sector Delay Clip for 4 mm gears is a tuning component designed to fine-tune dwell timing and nozzle actuation in AEG gearboxes. Made from durable CNC-machined POM (polyoxymethylene), this delay clip helps momentarily hold the tappet plate in position during the firing cycle, effectively extending dwell timing where needed. When paired with compatible tappet plates and internal setups, it can support smoother feed timing and reduce inconsistent trigger feel in higher speed or precision-focused builds.

Designed for use with 4 mm gear sets and Tokyo Marui–spec gearboxes, the Retro Arms delay clip provides an easy drop-in method to adjust internal timing without complex modifications. Its robust construction and tight tolerances help maintain stable performance under repeated cycling.
