- Available in three styles - a 0 MOA mount for zeroing your scope at short to mid range distances, a 20 MOA mount for zeroing your scope at longer distances, and a 30 MOA mount for serious long distance shooters.

One size does not fit all.
That’s why we designed the Monstrum Extended Series Scope Mounts. The Monstrum Extended Series Scope Mounts are built specifically for long range scopes - 6-24x magnification scopes and above - with longer dimensions and larger adjustment housing. With wider spacing between the two scope rings, the Extended Series Scope Mounts can accommodate scopes with larger segments that will not fit into standard one piece scope mounts.
Canted Downward at 20 MOA, the scope elevation is shifted 20 down MOA allowing you to account for bullet drop at longer distances.
Hardened Steel Torx Hardware
The mount is built for standard 30 mm tube scopes for mounting to any standard Picatinny rail equipped rifle.
The mount base mechanism comes equipped with custom Picatinny locking bolts that slot seamlessly into your Picatinny rail with zero wiggle - holds zero against the toughest of recoil.
The mount frame is crafted from lightweight 6061 grade aluminum with hardened steel Torx mounting hardware to prevent stripping of the bolts.
Square Integral Recoil Stops
The Monstrum Extended Series Scope Mount are built from the same platform as our best-selling Slim Profile Series. The design remains light and minimalist. At a mere five ounces, the weight is comparable to a set of lightweight rings, while providing the added rigidity and convenience of a one piece mount. The offset design provides an additional 2.00 inches of forward extension, allowing extra flexibility for optimum eye relief and shooting position.
