The TruGlo TG109 Lever Action Rifle Sights deliver a precise, high-visibility upgrade for Marlin 336 rifles, combining a red fiber optic front with a green fiber optic rear for rapid target acquisition in deep woods and low-light conditions. CNC-machined from durable steel and designed to replace the factory sights, these sights offer full windage and elevation adjustment to dial in your zero, while the dovetail base ensures secure, repeatable alignment. This fiber optic front/rear setup is engineered for straightforward, DIY installation in minutes and is not intended for carbine barrels, making it the ideal choice for hunters who value reliable performance and rugged construction. The front sight sits at a compact .060" diameter and the rear at .035", providing a clean sight picture that preserves line-of-sight while enhancing visibility at dawn, dusk, or dense cover. Built to withstand recoil and the rigors of field use, TruGlos Marlin 336 sights offer a durable, easy-to-use upgrade that preserves natural aiming confidence without compromising accuracy or speed.
