A yellow light means the chamber is empty. It also means that the system is connected correctly.
A white light means that a round is in the chamber and is ready to be fired.

Bolt Simulator: M249

Installing the bolt is easily done by sliding it into the slots in the M249.

After everything has been mounted correctly, do a test of the charging rod to make sure it is sliding freely.

Then put the buffer tube into the slots and push the pin in.
Insert the M249 recoil spring, then close up the back with the last pin to secure it in place.

When everything is closed up, test the recharging mechanism and the trigger mechanism to make sure nothing is stuck.
