The TruGlo TGTG975G is a green fiber optic front sight designed as a direct replacement for Marlin rimfire rifles. If you're running an older Marlin .22 or other rimfire platform and your factory sight is worn, damaged, or just not cutting it in the field, this sight swaps in to give you a bright, reliable aiming point without the need for batteries or electronics. The fiber optic design gathers ambient light and channels it to the sight post, making it exceptionally bright in low-light hunting and plinking sessions where a traditional blade sight might leave you squinting.
Built with precision CNC machining, this front sight is engineered to fit Marlin rimfire rifles without modification. The black steel construction is durable and corrosion-resistant—the kind of gear that handles real-world use. Installation is straightforward for anyone comfortable swapping a sight; no gunsmith required for most shooters. Because it's fiber optic rather than illuminated, it's always ready to go: no batteries to die in your pack, no buttons to fumble with when you need to take a shot.
Whether you're zeroing a squirrel rifle, setting up a plinker for the kids, or refreshing an old Marlin that deserves better iron sights, this TruGlo front sight delivers the visibility and reliability you'd expect from a trusted optics maker. It's a no-fuss upgrade that works as well in bright sunlight as it does in the shade.
