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.
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.

I recently got the Monstrum Extended Series Offset Picatinny Scope Mount (30 mm Diameter, 0 MOA) to pair with my new rifle scope, and it’s been a perfect match. This mount is designed for secure scope attachment on a Picatinny rail, and it’s proven to be a reliable choice for my setup.Quality and Build:The mount is well-crafted, made from lightweight aluminum with a matte black finish that matches my scope perfectly. The 30 mm rings are solid, with no wobble or flex, and the offset design provides just the right eye relief for my rifle. The screws and clamps are robust, ensuring a tight fit on the rail without any slippage. It feels durable and ready for range use.Performance:This mount holds my scope securely with zero issues. I mounted a 30 mm scope, and the offset design gave me the perfect positioning for comfortable shooting—no strain on my neck or awkward adjustments needed. It’s stayed rock-solid through multiple range trips, with no shift in zero even after recoil from my rifle. The 0 MOA design keeps things simple for my flat-shooting setup, and installation on the Picatinny rail was a breeze.Value for Money:At this price, the Monstrum mount is a great deal. It’s much more affordable than some high-end mounts but offers the same level of stability and precision. For anyone needing a reliable 30 mm scope mount, this is a cost-effective option that doesn’t skimp on quality.Minor Notes:Make sure your scope is 30 mm in diameter—this mount won’t fit other sizes. The offset design is great for eye relief, but it might not suit every rifle setup, so check your configuration. Also, a torque wrench is recommended for tightening the screws to avoid overdoing it.Overall:The Monstrum Extended Series Offset Picatinny Scope Mount is a sturdy, budget-friendly choice that keeps my scope locked in place. It’s well-made, easy to install, and performs flawlessly for my shooting needs. I’m happy with its reliability—5 stars for value and performance!

No need to buy expensive for nothing scope mounting systems that accomplish the same goal and are made from the same materials as the stuff Monstrum is putting out. Have a few of their products on different rifles from my .22s up to my .45-70 govt. They all hold up and do the job great. No issues, this offset mount included.

Purchased a Monstrum Hornet 6-24 ,my guns factory base didn't allow me to move rings far enough back to get correct eye relief. The offset rings gave me more than enough room and very stable. Bonus they look great also.

The Monstrum Extended Series Offset Picatinny Scope Mount, is OUTSTANDING in both fit and finish. Easily installed using the four included mounting screws, which fit as they should, and with 25 Inch lbs of torque, clamp the mount firmly to the Picatinny rail, and they stay there (unlike QD mounts). Personally, I have found these to be equal to my $125 Warne cantilever mounts, so I now have four of the Monstrum Extended Series Offset Picatinny Scope Mounts. They look great, work great and combine EASY AFFORDABILITY+EXTREMELY HIGH QUALITY= BUY THIS PRODUCT!

I love this scope base. It is great for larger optics (5-25x50) and seems super sturdy. I really appreciate the torx screws holding the unit to the pic rail. So much cleaner look than the finger screws or the socket nuts.I was unable to mount this to the expected rifle host however, and the reason I am giving 4 stars is the description need to warn or other wise show the dimension of the dual recoils stops. I was trying to use it to mount my scope to a Tikka T1X with a DIP pic rail adapter. However, this pic rail has a cut out for the ejection port and this prevents the mount from attaching anywhere on the rail. See pictures. I'm keeping the mount planning to use it on one of my other firearms in the future.
