Fully Upgraded M4 carbine.

I recently went to an airsoft store and asked for my m4 to be fully upgraded. I used last night at zombie night. Omg! It was amazing. I also tried my new p mag which you will see a pic of it on the bottom. I will post a video on M4 target shooting. Zombie night was crazy. They were giving away Saws!(See bellow) The zombie games were really awesome. I could not get any footage because they had Hollywood smoke in there. So I am sorry about that. Please look latter for my video on my M4.
On the top is the SAW.  
On the bottom is a Pmag.
