Nightforce Ultralite scope rings are offered in various heigts, from .885, 1.00, 1.125, 1.265 to 1.375 inches. The 1.1265 inch filles a gap in mounting options. All Nightforce rings are designed for 30mm riflescope tubes, and are regarded as some of the strongest, most rugged and precise mounting systems on the market. Nightforce Ultralite rings weigh 1/3 as much as steel rings, but the combination of 7075-T6 hard anodized aluminum with titanium crossbolts and jaws has proven, under rigorous testing, to be stronger than steel. Each is precision machined to match receiver contour, assuring straight and true alignment. This also reduces the amount of internal reticle adjustment when zeroing a rifle. One-piece and two-piece steel bases, plus Picatinny base blanks in steel or aluminum alloy are also offered.
