ARKEN OPTICS Halo Series billet precision scope rings are CNC machined from 7075 aircraft-grade aluminum that have ZERO tolerances for errors in any conditions.

With ARKEN’s endless pursuit for precision, HALO rings are machined in pairs for ultimate accuracy and consistency. Torx style socket screws along with enhanced recoil lugs result in amazing stability and secure mounting.

Arken Optics recommends max torque settings no greater than 25in/lb for ring screws and 45 in/lbs for base screws. The optic manufacturer's specification shall always supersede Arken's Halo Rings specification, unless higher.
