M60

The M60, officially the United States Machine Gun, is a 7.62 NATO LMG. It is a mid-range full-auto weapon with a large magazine.

Pros

 * Its large Mag and high fire-rate makes it easy to flush out enemies from their hiding spots and outright kill them.
 * It probably also has a high DPS.

Cons

 * It probably has less range than ARs and less damage per shot and maybe less spread. The weapon will slow you down more when holding it than ARs.
