Description
The DOUBLE M4 piston is a replacement internal part for M4-pattern AEG gearboxes. It is aimed at players and technicians who are stripping a gearbox to swap out a worn piston or building a setup from individual components. It sits in our Internal Part category with the other gearbox components we list.
It is listed as the Double Bell M4 piston. The information available covers the part name only, so no tooth count, material, weight or spring rating is quoted here; if any of those details matter for your build, compare the part with the piston you are removing before ordering.
Swapping a piston means opening the gearbox and reassembling it afterwards, so the job suits someone with experience of gearbox work rather than a first-time tinkerer.
