The XS Sights Lever Rail Mount for Marlin 336/308MX gives your classic lever-action rifle a modern optics platform without permanent modifications to the receiver. If you hunt with a Marlin centerfire and want the flexibility to run a scope, red dot, or other Picatinny/Weaver-mount sight, this aluminum rail unlocks serious versatility while preserving the gun's character. The design is straightforward: it mounts where the factory rear sight lives, opening up a clean path for contemporary glass or electronic optics.
What makes this rail genuinely useful is its length and mounting flexibility. The extended rail gives you multiple options: mount a scope directly over the receiver for conventional hunting sight picture, or push it forward toward the barrel for intermediate eye relief optics and red dot setups. That range of positioning is rare on lever-action mounts and means you're not locked into one sight picture or sight height. You can dial in what actually works for your shooting style and your rifle's ergonomics.
XS Sights engineered the rear of this mount to also accept their Lever Rail Ghost Ring Sight, so if you want to run irons as a backup or primary, the option is there. The rail itself is lightweight aluminum—no unnecessary bulk—and accepts standard Picatinny or Weaver-style rings, so you're not confined to proprietary rings or expensive adapters. Installation does require removal of the factory rear sight and gunsmith-level work is recommended to ensure it's rock-solid, which is worth the investment on a rifle you trust.
| Brand | XS Sights |
| Firearm Compatibility | Marlin 336, Marlin 308MX |
| Mount Type | Rail (accepts Picatinny/Weaver rings) |
| Material | Aluminum |

The rail accepts standard Picatinny or Weaver-mount rings, so you can use any scope, red dot, or other optic that mounts to those industry-standard interfaces. You're not limited to XS brand optics.
Yes. The rear of the rail is specially milled to accept the XS Sights Lever Rail Ghost Ring Sight for Marlin rifles, allowing you to pair optics with a mechanical backup iron sight.
The supplier recommends gunsmith installation. The rail requires removal of the factory rear sight, and professional fitting ensures the mount is secure and your rifle maintains zero.
The extra rail length gives you flexibility in where you mount your optic—directly over the receiver for standard eye relief, or forward over the barrel for intermediate eye relief scopes and red dots. This adaptability lets you optimize sight picture and handling for your personal shooting style.
