The Accu-Tac HSR300 30 MM Scope Rings Flat Black are purpose-built precision rings designed to give your optic a stable, repeatable mounting platform. CNC machined from 7075 aluminum alloy, these 30mm high rings feature a built-in bubble level to help you square your rifle and scope for consistent point of impact, while the flat black Type III hard anodized finish resists wear and blends cleanly with modern rifles.

These Accu-Tac rings are optimized for rifles using Picatinny mounts and scopes with 30mm tubes and objective lenses up to 56mm. The high profile geometry provides generous clearance over the barrel and handguard, supporting comfortable head position and reliable eye relief for extended range sessions or hunting use. Accu-Tac’s attention to tight tolerances and robust hardware delivers dependable alignment and long-term durability that serious shooters appreciate.
