Umarex / Elite Force / VFC MP7 Buffer

This is for the GBB version of VFC's MP7.

This is a buffer for the spring that is on the backplate of the MP7. That spring will over time wear down the material of the bolt-carrier group (BCG) of the MP7. With this buffer you will short-stroke the BCG by about 3.5mm and prevent wear of the BCG caused by the spring.

I recommend to print this with something strong but not brittle like some ASA mixes, PA12, a high durometer polyurethane or TPU.

If you get a failure to cycle after installing the buffer, then your nozzle return spring is way out of spec and should be replaced.
