The Era-Tac One-Piece Tactical QD Mount 30mm 75mm Offset Base Height 22mm (manufactured by Recknagel under part number T1033-0022) is a precision-engineered cantilever scope mount designed to clamp 30 mm optics onto standard MIL-STD-1913 Picatinny rails. CNC-machined from solid aircraft-grade aluminium and finished with a Mil-Spec Type III hardcoat anodised matte black coating, this unit features a 75 mm forward cantilever extension paired with a 22 mm base height (yielding a 37 mm optical centerline height). It incorporates Era-Tac's T1 series quick-detach clamping levers with integrated safety catches to prevent unintentional release while delivering 100% return-to-zero repeatability and tested recoil resistance rated up to .50 BMG.

Key Features

• 75 mm Forward Offset: Bridges optics forward on flat-top receiver rails to establish proper eye-relief on inline stock systems without spanning onto the handguard.
• Tool-Free QD Lever System: Baureihe T1 quick-release levers feature secondary safety catches to lock the mount securely against accidental disengagement.
• 100% Recoil-Proof Construction: Rated to withstand calibres up to .50 BMG while retaining zero across repeated field mounting and dismounting cycles.
• Universal Interface Ring Caps: Upper ring surfaces accept direct-mount secondary accessories, including red-dot sight adapters, angle cosine indicators (ACI), and backup iron sights.
• 0 MOA Flat Base: Provides a neutral, flat optical axis for platforms using scopes with sufficient internal elevation travel.

Who is the Era-Tac One-Piece Tactical QD Mount 30mm 75mm Offset Base Height 22mm for?

• Competitive IPSC Rifle and Australian PRS Shooters — Provides an exact 75 mm forward cantilever extension combined with a 37 mm centerline height on inline AR-15 platforms, allowing competitive shooters to maintain correct optical eye relief in dynamic shooting positions without mounting their 30mm cantilever scope mount across the receiver-handguard junction.
• Modern Sporting Rifle Hunters — Features quick-detach T1 safety levers engineered for tool-free, repeatable optic swaps on 30 mm tube rifles, maintaining a 100% return-to-zero across repeated detachments and locking securely under heavy field recoil rated up to .50 BMG.

Less suitable for: AR-10 platforms or bolt-action rifles where the 75 mm offset pushes the ocular lens too far forward, requiring a shorter 50 mm cantilever mount or a non-offset one-piece base; optics with 34 mm or 36 mm main tubes which require a larger-diameter mount series; or extreme long-range setups requiring built-in mechanical drop compensation beyond the factory 0 MOA inclination, which instead need a 20 MOA fixed offset or an adjustable inclination mount.
