Pros:

-Gorgeous model
-Awesome anims 
-Excellent Compile
 -Great choice of attachments(Surfire and ACOG)

Cons:

-Since what you did is a compile, I cant really count this against you. But I'll place my opinion on the texture none the less. Like the release on CSS, I still think the textures are a bit bright. Thats about all

Conclusion:

Great compile and awesome work. Its cool to see a modern fitting replacement for the good old black rifle. 
My opinion with the ACOG is: Is it not blocking the view? That is a personal opinion. Ill probably slap an eotech anyways. Awesome job mate.

On the side note:Some time since I posted in any HL2 related site.

I share your emotions against those 11 year old "know it all".
