TruGlo TG109 Lever Action Rifle Sights 0.343" Red Fiber Optic Front / Green Rear for Marlin 336

The TruGlo TG109 Lever Action Rifle Sight Set is a direct-replacement fiber optic sight package built specifically for the Marlin 336 lever-action rifle. It drops into the factory dovetail and pairs a high-visibility red fiber optic front with a contrasting pair of green fiber optic rear dots for fast, intuitive target acquisition in low light.

The sight bodies are CNC-machined from steel with a durable black finish built to handle the recoil and field use of a working lever-action. The set offers full windage and elevation adjustment, allowing shooters to zero the rifle to their preferred load and hold. The front sight stands 0.343" tall with a 0.060" fiber diameter, while the rear uses a 0.035" fiber pair to deliver a clean three-dot picture.

Designed as a replacement for the factory sights, the TG109 is intended for the standard Marlin 336 rifle configuration and is not for carbine barrels. Installation uses the existing dovetail mounts, making this a straightforward upgrade for hunters and shooters who want brighter, fiber-driven aiming without swapping out the entire sight system.
