Wanted to share a 2 parts I have been working on for the M4. I designed these and printed them in Nylon Carbon Fiber PA12-CF. I am still tweaking the design and looking for some feedback. They install the same as the factory handguards but do have 2 m3 socket cap screws that secure the 2 halves together using heat inserts. The flashlight mount is for a Fenix PD35 Tac but can be sized for any light.
