The spring is in the majority of airsoft guns today which is partly how to determine the guns power limit. Its the part that post people would usually switch out for something stronger or weaker for CQB.

G&P are a well known brand in the Asia market today due to their affordable AEG and parts. They've been making airsoft guns for awhile and know what the market wants when it comes to affordable yet quality guns.

The G&P AEG Spring is part of a series they've released which is designed only for the G&P AEG system, so please refrain from installing into other platforms.

Items included: 1x G&P AEG M120% Spring
