The RMS-106CS Hizack Custom is a mobile suit introduced in the anime Mobile Suit Zeta Gundam. Its design was later updated in the novel series Mobile Suit Gundam Unicorn. Known pilots included Sorama, Kara, and Gilligan Justas.

An improved version of the RMS-106 Hizack that specializes in long-range sniping. Its generator has been replaced with one that has higher output manufactured by Anaheim Electronics to operate a high-powered sniper beam launcher. The mono-eye has also been changed to a high-precision type, and the head's heat dissipation mechanism has been extended. Other improvements include its armor being reinforced with Gundarium Alloy, thicker armor, internalization of some vulnerable power cables, and a new backpack as well as thrusters to improve mobility. Overall, it has a modest performance boost over the original Hizack.

Only a limited number of Hizack Custom units were created to be used in special operations and sniper units for the Titans during the Gryps Conflict. After the fall of the Titans, Haman Karn's Neo Zeon movement took the Hizack Custom for their own use during the First Neo Zeon War. Most of the units were seized and used by the Zeon's ground force.
