Nikon 16155 S-Series Steel Riflescope Rings, Low
<b>S-Series Low Rings Black Matte (Steel)</b><br /><br /> The NIKON S-Series Low Steel Matte Black Rings (16155) incorporate a square, stainless steel recoil control key in both the front and rear rings.<br /> This ensures a "no slip" positive recoil surface across the entire Slot of the base that is capable of withstanding extreme recoil. <br /> They utilize four T-15 Torx-style socket cap screws per ring for secure optics mounting for increased strength and riflescope alignment. <br /> The ring band width is also substantially wider than typical rings, offering more ring-to-scope clamping area to hold the riflescope firmly in place.
