Trijicon® RMR®/SRO® Quick Release 45-Degree Offset Mount – AC32078
The Trijicon AC32078 is a professional-grade 45-degree offset mount designed to provide rapid, seamless transitions between a magnified primary optic and a backup red dot. In 2026, this mount remains the industry standard for tactical and competition shooters who require “passive” aiming capabilities for close-quarters engagements without adjusting their main scope. Featuring Trijicon’s proprietary Q-LOC™ Technology, the AC32078 offers a specialized spring-loaded, tool-less attachment system that facilitates one-handed mounting and removal. The mount is precision-engineered to provide a reliable Return-to-Zero, ensuring that your RMR or SRO remains perfectly indexed even after being removed for maintenance or transport.
Machined from high-strength 6061-T6 aluminum and finished in a Mil-Spec matte black anodization, the AC32078 is built to survive the harshest field conditions. Its snag-resistant, low-profile knob design minimizes the risk of catching on gear or brush, while the multiple proprietary recoil lugs ensure total engagement with any MIL-STD 1913 Picatinny rail. The mount is fully ambidextrous, allowing it to be positioned on either the right or left side of the receiver to accommodate both right- and left-handed shooters. Whether you are running a 1-6x LPVO or a high-magnification precision optic, the AC32078 provides the rugged, lightweight foundation needed to maintain a competitive edge in 2026.
Includes: (1) Trijicon Q-LOC™ 45-Degree Offset Mount, (2) Optic Mounting Screws, and (2) Hex Keys.
