Complete Recoil Spring Reinforced Buffer Spacer V2 set for MWS GBBR Marui SP System

SP System is an Asian brand offering excellent internal and external GBBR replica upgrade parts.

Here we find a V2 recoil spring and buffer spacer set made from reinforced polymer and metal in black and purple compatible with MWS GBBR series replicas from Tokyo Marui. Supplied with a reinforced recoil spring, four buffer spacer V2, five counterweights and a reinforced buffer. Will improve the kick of your replica by compressing the recoil spring more or less via the buffer spacer and counterweights to make the buffer heavier. Ideal for upgrading your GBBR airsoft replica!
