Vector Optics Offset Air Bubble Weaver Mount (SCACD-20) – Low-Profile 2″ Cant Level for Weaver/Picatinny Rails
The Vector Optics Offset Air Bubble Weaver Mount (SCACD-20) is a slim, precision level that helps eliminate rifle cant on Weaver and Picatinny rails. Milled from durable 6063-T6 aluminum and weighing just 11 g, this 2 inch offset bubble keeps your setup square without crowding your sight picture, making it a smart add-on for both tactical and precision builds.
Main Features
- Compact offset layout: At 51 mm in length, the bubble sits slightly off-axis so you can verify level without obstructing the optic.
- 6063-T6 aluminum body: Rigid, lightweight construction that stands up to field use.
- Featherweight: Only 11 g (0.4 oz) so balance and handling remain unchanged.
- Universal rail compatibility: Clamps to standard 21 mm Weaver or Picatinny interfaces.
- Matte black anodized finish: Low glare and strong corrosion resistance.
- Hex-key installation: Secure fit and easy fine positioning with the included wrench.
- Gen II refinement: Updated finish and consistent leveling performance.
