Mad Bull is proud to present the fully licensed Daniel Defense M4A1 RIS II. Daniel Defense is the sole provider of the RIS II to the United States Special Operations Command. The M4A1 RIS II adds to their already popular MK18 RIS II variant. Notable differences between the M4A1 and Mk18 version is the length, the M4A1 is 12″ vs the Mk18 which comes in at 9.5″. For those of you with a standard M4A1 barrel, this version is for you since the Mk18 version is more suitable for shorter barrels. Note that this rail is also compatible with mil-type M203 grenade launchers.
“The long awaited fully licensed Gemtech Raptor (dummy) silencer. The real Gemtech Raptor features a lightweight quick-detach design for use with the 9mm MP5 tri-lug mount, a simple push in and twist installation. The new MadBull version also features both a lightweight and a quick-detach design and fits over any airsoft MP5 tri-lug mount.”
