Here is a custom Cheek Riser I made for my Custom built marauder. It holds up to 3 magazines if desired but I will ideally hold 2 under it. The piece is made with kydex sheet and the clips are held in with 'spring' tension from the kydex itself. Very simple and elegant solution to the stock marauder's lack of ability to hold any mags on the rifle itself. You can blindly swap mags while in a holstered position which is a plus in case you forgot you already took your last shot on a current mag
