Barrel-mounted rear sight is machined from solid steel to deliver precise windage- and elevation-adjustable sighting while holding up under the toughest hunting conditions and heaviest recoil. Strong, stylish, ribbed base looks good on any rifle, slug gun, or muzzleloader. Screw tension locks the windage setting, and a spring-loaded push button release allows fast, easy elevation changes. Depress the button, move the slider to change setting, and release the button to lock the slider securely in position. Numbered, evenly spaced graduation lines stamped on right side of base ensure exact repeatability of settings. Elongated rear mounting hole in base accommodates center-to-center hole spacing of ½" to 1", including the 5/8" and 9/16" spacing used by earlier versions of Marble Universal Sight. Base and blades are sold separately; select the correct-size base for your gun, then choose the blade that suits your shooting requirements. Base includes slide mechanism and is available in sizes to fit .775", .875", and 1" O.D. barrels, plus flat base for mounting on flats of octagon barrels. Choose your base/slide by measuring the barrel O.D. at the position where the sight will be attached, then select the blade you want. Blades are interchangeable, so you can purchase extra blades for different shooting applications.
NOTES:
Base and blades are sold separately.
