I played around with the socom II, but it was just a bit nose heavy for me. I had wanted a scout M1A since they came out, maybe 10-12 years ago, but it never worked out.
I chose the original socom due to the superior compensator, and the shorter length, compared to the scout M1A. It is just a bit shorter than an M4, but with the power of a .308. It is the gun Neville should have been toting around.
