Elevation  Adjustment

Marble Arms® Standard Peep Tang Sight List by Manufacturer

The Marble Arms® Peep Tang Sight is adjustable for windage and elevation. The adjustments are micrometer precise. Each firm detent click equals four-tenths of an inch movement at 100 yards.

The Marble Arms® Peep Tang Sight is one of the cornerstones of our line. In the days when iron sights were the rule and scopes were the exception, the Peep Tang Sight was considered the top of the line in both precision shooting and general hunting. The increase in speed is due to the way your vision is drawn through the rear sight. You don’t have to acquire a sight picture. You are looking through the rear sight not at the rear sight. Just put the front sight where you want to shoot and squeeze the trigger. It’s the fastest sight combination for Cowboy Action Shooters. Webster Marble advocated a tang mounted peep sight on every hunting gun and called the Peep Tang Sight "the perfect rear sight." Once you use one, you will agree.
