Pros:

-Totally HQ Sounds 
-Realistic
-All Gun Weapon Sounds Changed

Cons:

-AK gunfire sound is way too loud if you use headphones
-SMG sounds like an Assault Rifle or Rifle
-Silenced SMG sounds like a toygun..

Conclusion:

It's an awesome mod, Just ignoring the Cons it will make it one of the best sound mods created so far
If the AK-SMG-SilencedSMG ever get fixed this will be the best of the bests.

Pros:

+ Good Quality
+ Everything works fine so far
+ Reloading is good
+ Better looking SCAR

Cons:

- None

Conclusion:

I love this mod., It actually makes me use the SCAR way way more than i used to. Getting a new sound for this weapon it would make it way way better
