The Vortex Hunter 1-Inch High (1.22 inches) Rings are a decent addition to a standard hunting set up. These rings use the typical 2-screw system and can be easily attached to a picatinny rail or a weaver rail. Made out of 6061-T6 aircraft aluminum, these rings are lightweight (1.55 ounces) but are also durable. Comes in 3 heights for one inch tubes.
