Vector Optics MAG Co-Witness Polymer Cantilever Mount — Black

Polymer saddle mount for red dot sights with MGT footprint (RMS-c compatible), designed to mount the Vector Optics Frenzy-S MIC and AUT red dots (SCRD-43 and SCRD-49) on 21 mm Picatinny/Weaver rails in absolute co-witness configuration with iron sights. With a saddle height of 28 mm and a weight of just 23 g, it suits shooters who want to keep their iron sight picture active without adding bulk to the firearm.

The cantilever design shifts the red dot toward the shooter, allowing a natural head position and reducing the need to adjust the grip or stock. The mount length of 36 mm and receiver width of 23 mm provide a stable footprint on the rail, while the receiver length of 40.8 mm offers sufficient clamping surface to resist recoil without requiring steel or aluminium.

The matte black polymer has been dimensioned to real-firearm specifications: this is not a lightweight dynamic shooting adapter for occasional use, but a component built to withstand sustained use on pistols and carbines in higher-recoil calibres while maintaining a consistent point of impact over time.

Key features

• Saddle height of 28 mm for absolute co-witness with standard iron sights, no modifications to the firearm required.
• Low weight of 23 g that does not affect the balance of the firearm or presentation time.
• MGT footprint, RMS-c compatible: fits the Frenzy-S MIC and AUT red dots directly, no adapter plates needed.
• Cantilever design brings the dot closer to the shooter's eye for fast acquisition and a natural shooting posture.
• Compatible with 21 mm Picatinny and Weaver rails, found on the vast majority of modern firearms.
• Designed for real firearms, with dimensional tolerances verified for recoil resistance.
