Accu-Tac HSR340 34mm Scope Rings - Flat Black Precision Mount

The Accu-Tac HSR340 34mm scope rings deliver rock-solid mounting performance for large-tube optics on precision rifle platforms. These rings eliminate the common issues of scope shift and inconsistent zero retention that plague standard mounting systems. Built specifically for 34mm diameter scopes, they provide the secure foundation required for long-range accuracy.

What Makes This Different

Unlike traditional rings that rely on simple clamping pressure, the HSR340 features a four-screw cap design with precision-machined surfaces that distribute clamping force evenly around the scope tube. The flat black anodized finish resists corrosion and wear while maintaining a low-profile appearance. Each ring undergoes CNC machining to achieve consistent dimensions within 0.001-inch tolerances.

Key Features

• 34mm tube diameter compatibility for modern precision optics
• Four-screw cap design ensures even clamping pressure distribution
• CNC-machined 6061-T6 aluminum construction for strength and weight savings
• Type III hard anodized flat black finish resists scratches and corrosion
• Picatinny rail mounting with recoil lugs for secure attachment
• Low-profile design minimizes scope height over bore
• Precision-ground contact surfaces prevent scope tube damage

Field testing demonstrates the HSR340's ability to maintain zero through temperature extremes and heavy recoil cycles. Competition shooters report consistent point of impact shifts under 0.25 MOA after hundreds of rounds in PRS matches. The rings handle magnum cartridges without loosening, while the anodized finish shows minimal wear after extended field use in harsh conditions.
