M1SURPLUS Weaver Style See-Through Long Scope Mount Rail for MARLIN Rifles – 2nd Gen Aluminum

Upgrade your MARLIN rifle with the M1SURPLUS Weaver Style See-Through Long Scope Mount Rail. This 2nd generation aluminum mount delivers a slim, durable platform that preserves your iron sights with a centered see-through channel, while giving you the option to add optics when the moment calls for it. The matte black finish blends with your rifle’s aesthetic, and the build is ready to handle the recoil that comes with field use.

Key features at a glance include a compact footprint and a lightweight profile: the rail measures 5.4 inches in length, stands 0.36 inches high, and weighs about 1.0 oz, keeping balance and handling unchanged for most shooters. The 7/8 inch wide Weaver-style rail accepts a wide range of rings and mounting options, from traditional scopes to red dots and reflex sights.

Designed for compatibility with Marlin rifles that have a factory-drilled top receiver for a scope mount, this 2nd generation aluminum mount is built to endure repeated firing while remaining precise and trustworthy in the field. A center see-through channel enables continued use of iron sights when optics are removed or swapped, letting you adapt to changing light or targets without losing situational awareness.

Real-world use and setup

This mount is a practical upgrade for hunters and target shooters who want a flexible optic solution without sacrificing the option to use iron sights. When you need rapid target acquisition, attach a red dot or reflex sight; switch to a traditional scope for longer-range shots, all while keeping a clear sight picture through the center channel. The result is a modular, lightweight system that supports a variety of optics configurations as your needs change from day to day.

Compatibility and installation considerations help you plan ahead. The mount fits Marlin rifles with a four-screw top rail drilled by the factory and is compatible with many popular models. If your older rifle doesn’t have drilled/tapped top holes, you may need additional drilling or mounting options. The unit ships brand new with a full manufacture warranty, and note that some items may be restricted from export.
