Xs Sights Lvrail Gr Sight Ws Mrlin/Rgr 336

The XS Sights Lever Rail for Marlin and Ruger 336 rifles is a precision-machined aluminum mounting solution that opens up your lever gun to modern optics without sacrificing the classic lines of your rifle. If you've been wanting to mount a scope or red dot on your 336 but balked at permanent modifications, this Picatinny-spec rail lets you add glass where it makes sense—directly over the receiver for traditional scopes, or forward for scout-style optics and compact red dots. Installation is straightforward: remove the factory rear sight, mount the rail, and you're ready to dial in an optic that suits your hunting or shooting style.

XS Sights engineered this rail from lightweight anodized aluminum to keep your rifle nimble in the field. The machining is tight to Picatinny specifications, so any standard optic mount will fit securely and repeatably. Whether you're running a low-power variable scope for close-range hunting, a fixed magnification optic for precision work, or a compact red dot for fast target acquisition, this rail gives you the flexibility to choose. The ghost ring iron sight set with white stripe front post stays on your rifle as a backup—a smart move for lever gun hunters who value redundancy and speed.

Installation requires attention to detail: all fasteners torque to exactly 20 inch-pounds. Over-torquing will strip or break the screws, so take your time, use a calibrated wrench, and you'll have a rock-solid platform that'll hold zero through seasons of hunting and shooting. This rail is compatible with Marlin 336 models (including those marked JM or Remington manufactured) and Ruger 336-pattern rifles, provided your rifle has the front sight installed in the ramp.

Frequently Asked Questions

Will this rail fit my Marlin or Ruger 336?

This rail is designed for Marlin 336 models (including JM-marked and Remington-manufactured versions) and Ruger 336-pattern rifles. Your rifle must have the front sight installed in the ramp for compatibility. If you're unsure about your exact model, verify the markings on your receiver before ordering.

Can I use both a scope and the included iron sights?

The rail replaces your factory rear sight, so you'll use the included ghost ring rear sight and white stripe front post as your backup iron sight system. If you mount an optic over the receiver or forward, the irons remain available as a quick backup option.

What optics can I mount on this rail?

Any optic with standard Picatinny rings will work—rifle scopes, scout scopes, red dots, and magnified optics are all compatible. The rail's design lets you mount closer to the receiver or further forward, depending on your sight picture preference and optic type.

How critical is the 20 inch-pound torque spec?

Very. XS Sights specifies 20 inch-pounds for a reason: over-torquing will fracture or break the fasteners and damage the rail. Use a calibrated torque wrench and stop when you hit that mark. Under-torquing can cause shifts in zero, so hit it right.
