Combat Union M4 Hop Up Chamber with M4 Air Nozzle

Combat Union M4 Hop Up Chamber with M4 Air Nozzle

Most standard hop-up chambers don't satisfy the players with their quality. They are too fragile, poorly feeding and spinning the bbs. Therefore, players choose to use custom parts.

This hop-up chamber has high reliability and stability due to its robust construction. The chamber allows you to set long buckings, and the feed system is designed so that the possibility of a bb skew is extremely low. The chamber comes with a nozzle and two o-rings. Made of duralumin on high-precision CNC machines.


The chamber is compatible with M AEGs from VFC and G&P, as well as with some from Cyma, G&G, DiBoys, LCT, Ares or King Arms. Works with Prometheus, Madbull, G&G, & Maple Leaf buckings. Possible problems with the LCT buckings.
