Lonex Cylinder Upgrade for Marui M4A1/SR16 Series AEG Gearboxes

The Lonex Cylinder Upgrade is machined from heat treated steel for durability, and is an AEG internal component upgrade that will considerably improve the efficiency and performance of your Marui M4A1 or SR16. This gearbox part is designed with cooling grooves to more effectively dissipate heat from friction created between the piston head and the cylinder. By polishing the interior of the cylinder friction is reduced and a more perfect air seal is formed, which stabilizes muzzle velocity.

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.
