Marble Arms 3X56 Sight

The Marble Arms 3X56 Sight is a fixed-magnification rifle sight built for hunters and shooters who need a rugged, reliable optic that works in changing light. This CNC-machined steel sight combines tritium illumination for fast target acquisition in low light with a recessed white ring that performs in daylight—giving you a versatile aiming solution without batteries or adjustments.

The tritium element provides that eye-catching glow when light fades, cutting through dawn and dusk when most game moves. The white ring isn't just bright in daylight; its recessed design protects it from scratches and ensures consistent light reflection from any shooting angle. That's the kind of thoughtful engineering that matters when you're in the field.

Built from steel and finished to Marble Arms' standard, this sight is made to last through seasons of hunting, range work, or tactical use. It's a straightforward optic that doesn't demand batteries or complicated reticle systems—just solid sight picture when you need it.
