Seekins 30mm Cantilever Mount 20moa

The Seekins 30mm Cantilever Mount 20MOA is a precision optics mounting system engineered for long-range rifle platforms requiring elevated sight lines and extended reach capability. Machined from billet 7075-T6 aluminum and finished with Type III Hardcoat Anodized matte black, this cantilever design positions the optic further forward on the receiver, enabling shooters to achieve proper eye relief with magnified scopes while preserving co-witness with backup iron sights.

The 20 MOA integral cant accommodates bullet drop correction at extended distances, reducing the need for maximum elevation adjustment on the scope turret and preserving mid-range zero accuracy. Seekins' MXM (Monolithic Extended Mount) rings measure 0.8 inches wide, providing greater clamping surface area than standard rings to distribute pressure evenly across the optic tube and eliminate the need for lapping or shimming during installation. The cantilever configuration distributes weight forward, which stabilizes long-reach setups common in precision rifle competitions and tactical applications.

This mount is suited for shooters running quality 30mm tube optics on AR-platform rifles, bolt-action precision rigs, and similar modern sporting rifles. The 30mm standard accommodates premium variable-magnification scopes with larger objective lenses and robust adjustment mechanisms. Precision-minded users—from competition shooters to long-range hunters—benefit from the rigid platform this design provides, as any flex or movement between rifle and optic directly impacts shot placement downrange.

Seekins Precision holds a solid reputation for holding zero under harsh handling and sustained fire. The cantilever mount is a mainstream choice in the precision rifle community where engineering and repeatability are non-negotiable.
