Also fits scopes with similar ACOG Style Bases such as the Burris AR-332 and newer model Trijicon RX-30 optics with 3 inline mounting holes. The Sightmark Wraith QD Mount is compatible with the Sightmark Wraith HD and 4K line of Digital Riflescopes. The overall length of the base is 3.5" and the centerline height with a TA-31 ACOG is 1.62". It is precision machined from 6061 T6 aluminum and finished in hard coat T3 Mil-Spec anodize. It features the Patented QD Auto Lock(tm) Lever system to accommodate both in spec and out of spec rail systems.
