The ASG Ultimate M4 / M16 Aluminum Hop-up Chamber is an essential compression upgrade component for any compatible AEG. This ASG hop-up chamber provides all the necessary parts needed to install onto your AEG in addition to an o-ring around the loading chamber of the unit, giving you the absolute best compression against your gearbox. For best results, it is recommended that you pair this hop-up unit with an aftermarket air nozzle that has an internal o-ring installed.
NOTE: Airsoft Megastore recommends that all internal upgrades and or repairs be handled by a qualified airsoft technician. Airsoft Megastore is NOT responsible for improperly installed replacement or upgrade airsoft parts. DO NOT disassemble your airsoft gun within Airsoft Megastore's warranty period, as this will VOID your warranty.
|Compatibility||Designed to fit most M4 / M16 metal bodies. This hop-up unit will fit plastic body M4 / M16s with some slight modification.|
