The ERA-TAC Aluminum Scope Ring with Universal Interface (30 mm) is a precision German-engineered optic accessory designed to clamp directly to a rifle scope's main tube while providing a rigid platform for mounting secondary accessories. Machined from high-grade solid billet aluminum and treated with a Mil-Spec Type III hard-anodised matte black finish, the ring provides reliable clamping under heavy tactical recoil. Featuring a symmetrical half-split design, it allows 360-degree rotational positioning around the optic body, enabling shooters to run secondary devices at 12 o'clock, 45 degrees, or 90 degrees before torquing.

Key Features

• ERA-TAC Universal Interface: Integrates Recknagel's proprietary tactical mounting platform directly onto the ring cap, allowing direct attachment of secondary Picatinny rail sections, red dot adapter plates, or infrared illuminators.
• 360-Degree Rotational Freedom: Clamps symmetrically around the optic body to permit custom rotational alignment for top-dead-centre or offset auxiliary setups.
• Solid Billet Construction: Machined from solid aluminum with a Mil-Spec Type III hard-anodised finish for resistance against environmental abrasion and corrosion.
• Complete Fitting Kit: Includes the 30 mm middle-tube ring, mounting screws, and the required fitting wrench for installation.

• Inner Ring Diameter: 30 mm (1.181 inches)
• Ring Width: 18 mm
• Interface Base Height: 3 mm (compatible with optional ERA-TAC spacers for height adjustment)
• Material: Solid billet aluminum
• Finish: Hard-anodised matte black (Mil-Spec Type III)
• Tube Split Configuration: Symmetrical half-split (middle-tube application)
• Power Requirements: Passive mechanical accessory (unpowered)

Who is the Era-Tac Aluminum Scope Ring With Universal Interface 30mm for?

• Long-Range Precision Shooters — Needs a low-profile 3 mm base interface to mount secondary reflex sights or laser illuminators directly to a primary 30 mm optic without obstructing elevation turrets.
• Tactical PRS Shooters — Requires an 18 mm clamping surface to rigidly secure offset secondary target-acquisition sights to a 30 mm main tube for rapid transitions between barricade positions.

Less suitable for: Optics with 1-inch, 34 mm, or 36 mm main tubes, or setups with less than 18 mm of continuous, parallel tube clearance; these configurations require diameter-matched scope rings or dedicated single-split objective bell mount rings.
