Description
The Steiner T-Series rings are built for precision tactical shooting, where a scope that shifts under recoil or loses its zero between range sessions is a genuine liability rather than an inconvenience. Steiner engineered this set to keep a riflescope in consistent optical alignment shot after shot, which matters most on a dedicated precision platform where the same zero needs to hold across extended strings of fire or varying field conditions.
The 34mm tube diameter accommodates the larger main tubes found on many modern tactical and long-range optics, tubes that manufacturers use to allow greater internal adjustment travel — useful when dialing for extended range or compensating for significant cant. Choosing the high-mount height positions the scope’s centerline higher above the bore, which is the correct choice when running optics with large objective lenses that would otherwise contact the barrel or rail, or when a more upright, natural cheek position is needed with a particular stock profile.
A bubble level built into the rear ring is worth noting for precision work: cant introduces horizontal error that grows with distance, and having a reference point directly on the mount means the shooter can verify level without relying on the optic itself or a separate add-on. The rings mount to Picatinny rail, the mil-spec cross-slot standard that provides positive indexed positioning and eliminates the rotational slop associated with smooth-tube Weaver-style bases. Construction is steel with a matte black finish, giving the set the mass to handle hard-recoiling calibers without deforming and the corrosion resistance expected from field equipment.
