Pros:

+ Great model.
+ Great textures.
+ Great sound.
+ Great animations.

Cons:

- I will miss that 'HK slap' in the reload animation. No points docked for this, though. It's just personal preference, and this animation is excellent all the same.

Conclusion:

Brilliant! I've been hoping someone would port this over since I saw it released for FNV. Now that it's here, this is easily my favourite military sniper replacement.
