Rail space runs out fast once you start adding accessories. This scope-mounted Picatinny rail clamps to your scope tube and adds 120mm of standard Picatinny rail without touching your rifle's existing rail sections. Built from high-strength PPA with metal threaded inserts, it weighs 55 grams and fits most scopes with a hood diameter of 57mm or less. Particularly useful on rifles with canted scope mounts, where accessories need to stay aligned with the scope body rather than the rail.

Key Features:

• Generous Rail Space: 120mm of picatinny rail provides ample room for mounting laser designators, IR illuminators, thermal imagers, rangefinders, and other essential accessories

• Enhanced Construction: Built from high-strength PPA (polyphthalamide) with metal threaded inserts for superior rigidity and durability while maintaining minimal weight at just 55 grams

• Advanced Illuminated Level Option: Available with integrated bubble level featuring removable glow-in-the-dark inserts that charge during daylight or can be upgraded with your own tritium vials* (3×15mm) for 10+ years of continuous illumination (additional information about inserts here)

• Broad Compatibility: Works with most scopes featuring a hood diameter equal to or less than 57mm (virtually all scopes with 50mm objective lens or smaller)

• Non-Marring Design: Polymer construction ensures your scope tube remains pristine

• Precision Setup: Pairs perfectly with our Precision Wedge Level (sold separately) for complete rifle alignment system

• Simple Installation: Quick and secure mounting using a 4mm hex key (not included); level version requires stub-length 4mm hex key

• Custom Options: Special orders available for different tube diameters, objective diameters, and lengths

Available in standard or illuminated bubble level variant, with 1-inch, 30mm, and 34mm tube diameter options. If you need more mounting real estate without adding bulk, this is the direct solution.
