The Monstrum Low Profile Dovetail to Picatinny Mount is a compact rail adapter designed to bridge classic dovetail bases with modern Picatinny and Weaver optics. It suits airguns and select 22 rimfire rifles that use 11 mm or 3/8 inch dovetail setups, offering a solid platform for sights, red dots, and sporting optics.
Available in three practical lengths, this mount preserves a low silhouette while expanding your mounting options. The design emphasizes stability, repeatable alignment, and a clean, minimal profile that helps maintain rifle balance during handling and shooting sessions.
Choose from 9-slot, 14-slot, or 17-slot versions. The extended rail adds about two inches in front of the base, enabling more forward placement of long eye relief optics. Whether you prefer a compact setup or maximum accessory space, there is a Monstrum option for you.
Crafted from 6061 aluminum, the mount delivers a sturdy yet light foundation. Hardened Torx mounting hardware helps prevent bolt stripping during installation or field adjustments. The dovetail to Picatinny interface accepts Picatinny or Weaver standard scopes, red dots, and other optics, broadening your mounting versatility.
Imagine pairing a compact red dot with a lightweight rifle, or mounting a longer eye relief scope for field shooting where distance to the optic matters. The extended rail lets you tailor optic positioning to your preferred shooting stance and setup. For best results, verify dovetail dimensions on your base and torque hardware according to guidelines to maintain alignment over time.
Monstrum combines practical design with robust materials to deliver a reliable mounting solution. While results vary by firearm and optics, the low profile and extended options offer flexibility for upgrades and customization, helping you build a setup that feels right for your needs.
