Has anyone installed a SAV-2 on a rifle that originally had the Bottom Bolt Release and Accustock in a TAC-21 or similar chassis.

According to the literature the SAV-2 will not work with bottom bolt release and accustock but i'm wondering if taking the Accustock out of the picture makes a difference? The MDT Tac-21 accommodates both the old Top bolt release AND bottom bolt release triggers so I'm guessing it should accept the SAV-2 but hearing how it might have worked for others would be great.

Anyone?
