Pros:

- Incredibly accurate model.
- Accurate reproduction of the weapon's vietnam theme.
- Awesome muzzle flash.
- Very different, very realistic weapon sounds, particularly firing sounds.

Cons:

- None that I can think of at this stage. Unlikely to be any in the future.

Conclusion:

A great weapon all round, one of the few that I would consider giving a rating of "10"

A lot of work has obviously been put into this and it is a mod I will be using for a long time!
