Vector Optics Universal Flat Bubble ACD Mount Anti-Cant Level — Matte Black

The Vector Optics Universal Flat Bubble ACD Mount is a second-generation anti-cant device (ACD) designed to attach to any flat surface on a firearm, letting the shooter verify at any moment that the rifle has no lateral tilt. At 47 mm long and just 12 mm wide and tall, it sits without bulk on optics bodies, scopes, rails and side rails.

Even slight cant introduces a systematic error that grows with distance: at 200 metres, even a few degrees of tilt shift the point of impact in a way that turret adjustments alone cannot correct. The immediately readable bubble allows the shooter to eliminate this error before each shot, making the check a natural part of the aiming routine whether on the range or in the field. The GenII version improves bubble readability and mount retention compared to the previous generation.

The 6063-T6 aerospace aluminium alloy construction provides recoil resistance without adding meaningful weight: the device weighs just 7 grams, a figure that does not affect the balance of the rifle or interfere with grip and ergonomics. The matte black finish reduces reflections under raking light conditions.
