ADVANTAGES OF S&K MOUNTING SYSTEM
-Front and rear rings are interchangeable
-Ring studs mate to matching receptacles in bases
-BOTH rings bear against front of their respective receptacles (both absorb recoil shock)
-Trim in appearance, light in weight
-Precision bored – scope will not slip
-No knobs, bolts or other obtrusions to break or bend
-Fit any 1 inch scope tube
All S&K rings are fully machined out of solid steel bar stock, tumble finished to remove all burrs, and have a 3/8" diameter stud that locks into a 3/8" hole or slot in the base which provides windage adjustment. The rings are locked into position by tightening cooperative cone pointed set screws. The rings are precision bored to 1" diameter and, being machined rather than extruded or stamped, form a precision fit that will not slip under recoil. They are nicely contoured and trim in appearance. S&K rings are tumble finished and blued to achieve a military-type dull or nonglare black finish that matches the black anodized Insta Mount bases.
