ZCI 10in Aluminum RIS Foregrip

This is a decent free float rail for the money. The first review was correct as the rail does not sit true and center. The rail has sharp edges throughout the build. The finish is nice. The rail is rather large for a free float. If you're looking for something slim and high-speed, this is not the rail for you. If you're looking for Madbull quality, this rail is not for you. I have mounted this on a Tokyo Marui M4, King Arms Colt M4, and G&G GR16. Rail did not sit straight for any. This rail would install properly on an Ares M4.
