The ERA-TAC Picatinny Adapter, Side Version (model T0913-0000) is a German-engineered mounting accessory manufactured by Recknagel. It bolts directly to the proprietary ERA-TAC UNIVERSAL-Interface found on ERA-TAC tactical ring tops, block mounts, and one-piece mounts to provide an external MIL-STD-1913 attachment point. Featuring an engineered 20° downward offset from the primary optic plane, this adapter positions secondary tactical devices clear of scope turrets and handguard rail space. Precision CNC-machined from aircraft-grade aluminum and treated with a hard-anodized matte finish, it integrates into heavy-recoil systems rated up to .50 BMG calibres.

Key Features

  • 20° Side Offset: Positions the rail downward and away from the main optic plane to prevent secondary accessories from obstructing the scope sight picture or turret adjustments.
  • MIL-STD-1913 Interface: Provides a 35 mm rail section compatible with compact single-crossbolt weapon lights, lasers, and auxiliary shooting gear.
  • UNIVERSAL-Interface Integration: Mounts securely using included Torx fixing screws directly to pre-machined ERA-TAC ring tops and block mounts.
  • Heavy-Recoil Construction: CNC-machined from aircraft-grade aluminum to withstand extreme magnum firearm recoil when torqued to specification.
  • Passive Mechanical Design: Completely mechanical component requiring no batteries, external power, or wiring.

Who is the ERA-TAC Picatinny Adapter, Side Version for?

  • Precision Rifle Series competitors — who need this Picatinny scope mount adapter to run auxiliary equipment angled 20° downward from the optic body to keep turrets clear and unobstructed during matches.
  • Long-range hunters — mounting compact secondary equipment such as micro-lasers or small lights directly to their ERA-TAC one-piece mounts via a minimal 35 mm Picatinny rail section without adding bulk to the rifle forend.

Less suitable for: Shooters requiring a 12 o'clock, top-dead-centre position or those mounting multi-crossbolt hardware exceeding 35 mm in clamp length; these applications require a centric top-mount adapter or a longer 55 mm to 85 mm rail platform. Additionally, it cannot mount directly to receiver rails, M-LOK, or KeyMod surfaces without an underlying ERA-TAC UNIVERSAL-Interface base.
