Farrell Rings are precision CNC machined from a single piece of solid steel or aluminum. They are a Picatinny system that will mate with any 1913 Mil Spec Picatinny Mount. When used with the Farrell Scope base, it is our goal to have a center line with less than .001 inch deviation. Most rings are made in either aluminum or steel. With a black matte finish. They are made in five different heights in both 1 inch and 30MM. The new design of Farrell rings are grooved on the inside of the diameter to reduce weight and improve clamping,  We recommend to not use loctite with our taper head screws as they utilize a 360 degree mating surface.

The Farrell clamp to the rail, we believe is second to none. The ring cross bolt is located concentric across the dovetail angles and pulls the ring down and over to the centerline of the base, creating an even pressure. This enables the torque to be applied in such a way as to prevent stressing and moving the center line of the ring.

The clamp is designed to pivot on all surfaces to assure proper contact on the rail, the ring and the cross bolt. This is accomplished by using a radius on all points of contact.  This is very important, especially when different manufacturers of  rails might have different dimensions across the 45 degree angles that all rings mount on (picatinny or weaver style).

  • RING HEIGHTS - 1" and 30mm ( From the Top of the base to the centerline of the tube. )
