Pros:

A fantastic M1 carbine Model
Excellent textures with good detail
Good animation
Mostly decent sounds. See Cons.

Cons:

The actual gunshot is far too base-y for the round it should be firing. It sounds like I'm firing a cannon from the 1800's. If you redo the gunshot I'd recommend a less base-y crisper sound. (-1) (on a side note, I miss the old scoring system. I would have only taken .5 off but I can't with these stars)

Conclusion:

It's a good replacement for the hunting rifle, however I'm going to have to do something about the firing sound it's too distracting. If you ever redo the sounds this video has some dude firing an M1 carbine ( https://www.youtube.com/watch?v=sjy6FRWOmhc ) that would definitely help for basing the sound. 
Overall this is a good replacement for the Hunting Rifle, I would definitely recommend trying it. Perhaps the sound wont bug you as much as it bugs me.
