Muzzle break designed for the (2019) H&K MP7 AEG.
This version is designed to work with the ACETECH Lighter S tracer unit.
I have included the barrel adapter I made to mount the tracer as well as the cover I printed for the tracer.

Increases the length of battery that can fit in the gun.
Fits flush with top rail riser or has a matching rear riser.
Top rail riser split into three pieces for easier printing.

See my original muzzle brake linked below for the rail riser pieces.

It has holes for #6-32 screws to secure the top rails but friction seems to get the job done.

While the Adapter I designed works, this muzzle is also compatible with the 12mm to 14mm CCW sold by Lees Precision Engineering.
