Systema Reinforced 7mm M4/M16 Series AEG Gearbox (Black)
[02991 / CMB-C1625]New to airsoft? Here are some safety tips for airsoft guns that we recommend following.
Description:
The Systema 7MM Reinforce Gearbox for M4/M16 is the best way to upgrade your gearbox if you are shooting high fps, 420+. The purpose of the 7mm ball bearings is to reduce the friction put on the gears fulcrum while spinning. Don't make the mistake of thinking the only way your gears can break is at the teeth. High power springs with mediocre bushings or bearings can break the gears at the stem. A break at the stem is potentially more dangerous to the gearbox than just a few teeth breaking off. The Systema 7mm Reinforced Gearbox is designed to prevent damage to the gears and to prevent gearbox failure due to high stress. If you like your high powered gun performing in tip top condition you need this reinforced gearbox.
