And another project.
After I finished the M3A1, I found out that the Philipine Army had upgraded some of their M3s with custom built supressor and rails and some fancy paint. I wanted to do the same with the model I had, but at the same time I did not want to spend a lot of time on it. I only spent two days on it, modifying the parts, adding the rail and modelling the sight after some cheap reflex sight from China.
If you want more info about it, theres a great read here on TFB:
