BB Stopper + Spring Upgrade For SSG10 / VSR 10
Upgrade part to standard SSG10 / VSR 10 HupUp-Chamber to avoid double-feeding from stronger magazines like Action Army VSR10 50 rounds or when using M4 Midcaps magazines with the M4 adapter.
Made from CNC machined aluminium. The spring can also be used alone on the regular SSG10 Plastik BB plug.
This upgrade part may cause your sniper to sound slightly louder.
