Madbull Daniel Defense 4" Lite RIS Kit for Airsoft M4 / M16 Series (Color: Black)

"Fantastic little rail. Another quality Madbull product!
10/10

"Threw on my combat machine. Looks great. Solid. Shoots great. With this and some krytac internals, what was an eye sore of a gun is now arguably one of my favorite pieces.

"This is a great rail system! Only one complaint is that this is off by 2-3 millimeters of from being mil-spec. So things can get stuck on the bottom. Looks great with the gold kx3 noveske amplifier. It could have to be re threaded on a kwa.
