For: Madbull 12" Daniel Defense M4A1 RIS II (Black)Product Information:
this rail came as a part of a daniel defense rifle i purchased. the 2 piece design is quite brilliant, i never ended up utilizing it, but it didnt add extra weight, and it doesnt hurt to have.
-brilliant 2 piece design for m203 design
-free floating rail that doesnt move a millimeter.
-cant go wrong with daniel defense.
(for anyone wondering, the 2 piece design does not create a rattle, its very sturdy)
it is rather heavy, but your buying a 12" rail, so you should expect your gun to become front heavy with one of these.
