APS 8mm Complete Quick Spring Change M4 Gearbox Ver.2 Rear Line


A very solid and well put together V2 gearbox. The electric blow back functions well and can be removed if it wont fit in your receiver.

The supplied spring appears to be an M100 chronographed at around 340 fps with 0.25g bbs.

Overall very impressed and will definitely buy again for my next build.
