Hi,
After a crazy day at work in the IT business, there is nothing like building an M2 Machine gun to change your mind.
The Clark TK-60 control board has 2 machine guns with flash and sound. So, in addition to the coax machine gun, I decided to give flash and sound to the commander's M2 machine gun. Since I gave the cupola some horizontal mouvement, it is logical to also be able to shower the front of the vehicle and get those VCs.
This is the Aber M2 brass barrel, getting ready to be cut, drilled and modified. It is not obvious to do. I did it once for the cupola MG on the M48 build but this time, it is for a complete standalone M2 on its external mount.

The solid brass barrel is cut at the larger sleeve level, and the sleeve is drilled and made hollow to carry a fibre optic through it.

Here, the thin solid brass barrel will be replaced by a brass tube that will be extensively reworked to replace the barrel with a good look and feel of the original.

After much hand file sanding to make the tube progressively thinner towards the tip, then polishing and adding a larger muzzle with the same brass tube, the new brass barrel is connected to the sleeve area with the fibre optic running through it.

As the TC machine gun is well protected behind a gun shield, the plan is for the fibre optic to go down through the MG mount and then inside the turret where a LED will be connected. The fibre should be well hidden.

The barrel is mounted on the Tamiya M2 body.

The M2 is given an Aber PE treatment to optimize the details. I've build the Aber M2 many times now, it is somehow getting easier all the time. What was taking me hours and a lot of cursing years ago is now done in minutes...

Still have to attach a few extremely small PE details, but its getting dark.

Here we are, a 1/16 scale M2 Machine gun with fibre optic gun flash ready to be installed on its mount.
