Pros:

Very good reanimation, now you can see what's in front of you when you're reloading in the dark.

Cons:

A lot of autoshotgun skin mods out there incorporate arby's old animation. Thus you have to use default autoshotgun skin or those that does not come with custom animation (probably not so nice ones either) to prevent conflict.

Conclusion:

Great reanimation unfortunately I will not be using it because i value looks over (not sure what word to use) performance. Hopefully there will be new autoshotgun skins that incorporate it or authors of the skins I am currently using will update.
