Product Overview

Built for Aussie lever-gun shooters who actually get out and use their rifles, the Talley RMR to Marlin 336 Red Dot Base gives you a rock-solid way to run modern RMR-footprint optics on a classic Marlin. Machined in the USA from lightweight 6000 series aluminium alloy and finished in hard-wearing black anodising, it keeps weight off the rifle while handling real field abuse – dust, recoil and rough travel in the ute. The compact footprint keeps your red dot low and tidy on the receiver, so you get fast target acquisition without a bulky rail getting in the way.

This direct-mount base is purpose-built for RMR pattern red dots (including popular options like the Holosun 507C series), so you can bolt your optic straight on without extra adapters or Picatinny rails. Precision CNC machining and tight tolerances mean the base lines up true with your bore, helping you hold zero through hard use. Supplied with mounting screws and wrench, it’s a straightforward upgrade for hunters and bush shooters who want quicker shots and better visibility from their Marlin 336 without turning it into a boat anchor.
