Looks cool with the carry handle or with the iron sight, don't you think? I know that all together it's little expensive, and only it is a freak customization of your weapon, but if you love guns, you'll love these!! Really I made it for me to use with the add-ons from my friend MortenRidderseth and Jimmmmeh, but if you are a guns nut, you will like it. Choose the way you fire with your M4!
