The Marble Arms 45-MR is a precision steel front sight engineered for universal rifle applications. Standing .450″ in height with a .340″ wide base, this sight features a contoured blade that slopes toward the front and carries the distinctive design standard established since 1900.
Construction combines solid steel with a blued finish and a .060″ diameter fiber optic rod in green. The fiber optic cable is permanently flared to the sight with both ends carefully polished to enhance light transmission and protected from UV damage due to long term exposure to sunlight. Precision CNC machining from solid steel ensures each sight meets exact standards, with finishing work applied to match your gun.
The sight installs into any front sight ramp with a 3/8″ dovetail and features an average width of .340″. The green fiber optic glow delivers excellent visibility in low-light conditions while preserving the classic aesthetics of your rifle, making it the choice for precision shooters and serious hunters.
