Midwest Marlin 336 Handguard Adapter

The Midwest Marlin 336 Handguard Adapter is a purpose-built mounting solution that modernizes the classic Marlin 336 and 1894 lever-action rifles by enabling attachment of M-LOK compatible tactical rails and accessories. Law enforcement trainers and private shooters have long sought ways to add modern optics mounts, lights, and handguards to these proven platforms without permanent modification. This adapter delivers that capability with a clean, reversible installation that preserves the rifle's original profile while unlocking contemporary accessory compatibility.

Engineered by Midwest Industries—a trusted name in modular rifle solutions—the adapter features a precision-machined design that interfaces directly with the Marlin 336 handguard area, creating a stable M-LOK platform for rail mounting. The compact footprint (2.25 x 2.25 x 4 inches) and lightweight construction (0.19 lbs) ensure minimal weight penalty while maintaining zero shift during installation and removal. The adapter's design allows shooters to integrate Midwest Industries M-LOK rails without drilling, tapping, or permanently altering the original firearm, making it ideal for users who value platform versatility and reversibility.

This adapter benefits hunters, sport shooters, and defensive marksmen who rely on Marlin lever-actions but require modern rail-mounted accessories such as tactical lights, red dot optics, or supplemental handguards for improved ergonomics. Installation is straightforward and requires no gunsmithing—standard hand tools suffice. The M-LOK interface ensures compatibility with the broad ecosystem of aftermarket tactical components, allowing users to customize their platform for specific mission profiles while maintaining the rifle's traditional handling characteristics and reliability.
