With 11 game-changing innovations, the RDB is the new definition of bullpup. Its downward shell ejection system eliminates the side ejection disadvantage of ordinary bullpups. The result is casings that eject out of your line of sight and a truly ambidextrous, high performance rifle. The RDB is also adjustable for a wide variety of ammunition. It’s definitely the bullpup done right.

A:yes it uses AR style mags (magpul pmags or lancer mags) you can add a foregrip as the OAL is 27.5 inches "unless your AR pistol has an OAL greater than 26 inches then you should not add a vertical fore-grip unless you first submit a Form 1 and get it approved."
