Internal Airsoft Spare Parts

Internal components for airsoft guns: gearbox, gears, pistons, cylinders, springs, motors, hop-up, hop-up bucking and inner barrels.

Replacement or upgrade

A stock replacement part restores the airsoft gun to its original condition. An upgrade changes performance: a different spring alters the power output, a precision inner barrel and quality hop-up bucking improve trajectory, and a high-torque motor sharpens trigger response.

The key factor is the gearbox version (V2, V3, V7…) or the GBB platform: parts are not interchangeable between versions. After any power modification, test the airsoft gun with a chronograph.

Slides, bodies, compensators and flash hiders are listed under external airsoft parts.
