||so.. Evike gave me these rails for free with my G&G m4 before they even came out..
they have no markings or anything on them so i think they were a prototype .-.
but yeah.. they're really nice and easy to install/uninstall
that metal piece that's in the second picture just screws right onto the body of your gun then they rails mount right onto that so its really easy and they don't wobble or move at all.
easy to install
heavy (could be a con too)
paint doesn't scratch easily.
kinda expansive.. but if you're willing to pay the money the're really nice
