Guarder Airsoft M4 M16 High Performance Hop Up Unit Housing

Guarder M4/M16 Metal Hop Up Chamber

At Bullseye Country Sport, we've found that a worn hop unit can cause a surprising number of problems, from inconsistent feeding and poor air seal to erratic shot placement. When diagnosing accuracy issues, the hop chamber is often one of the first components worth checking.

The Guarder M4/M16 Hop Up Chamber is a replacement hop unit designed for compatible M4/M16 AEG platforms. Manufactured from cast alloy, it provides a durable alternative to worn or damaged factory hop units and is well suited to both repairs and rebuilds.

Using the traditional hop adjustment design found on many classic M4/M16 AEGs, this chamber offers straightforward adjustment and reliable operation. Whether you're restoring an older rifle or replacing a damaged chamber during maintenance, the Guarder hop unit provides a solid replacement for compatible builds.

Compatibility Note: Designed for Tokyo Marui-spec M4/M16 AEG platforms. Compatibility with all manufacturers cannot be guaranteed, particularly where proprietary hop units, receivers or gearbox arrangements are used. Please verify compatibility before purchase.
