A customized Graze used by Gjallarhorn's internal regulatory unit, Ollerus. It is capable of carrying out attitude/posture controls that are impossible for other mobile suits due to the wire claw on the left forearm as well as the fixing arms on the shoulders, knees, and feet. Additionally, the shock absorbers in its legs were also enhanced, reducing the noise made by the suit. Using its stun stick, the Graze Stachel engages in hit-and-run and other highly discreet attacks.

The Graze Stachel was the mainstay mobile suit used by Gjallarhorn's internal regulatory unit, Ollerus, which is commandeered by House Nadira. The Graze Stachels were deployed numerous times in attempts to capture Mina Cerulean, who was actually Mina Zalmfort, from Tanto Tempo's custody.
