Pros:

Great skin
Good reloading ( i waiting it since a long time :D )
well fitting for the M16 replacement

Cons:

It can be as cool as with no scope ^^

Conclusion:

It is a very great gun and if you can create a skin of the same gun but with no scope it can be cool ! :D 
But it isn't a reason for don't give a 10 for this gun ! :D
