AD mount for Vortex Spitfire 3x, Titanium Lever

• Quick-detach Auto Lock lever: The patented QD Auto Lock lever lets the mount come off and go back on quickly while maintaining a secure hold on the rail, which is useful when swapping optics or moving between rifles.
• Titanium lever assembly: The titanium lever reduces lever weight while increasing strength and corrosion resistance, giving the mount a lighter feel without giving up durability in hard field use.
• Spitfire 3x-specific fit: This mount is made as a replacement base for the Generation 1 Vortex Spitfire 3x, so it matches the optic’s footprint and provides a cleaner, more purpose-built setup than a generic adapter.
• Adjustable rail interface: The lever system is designed to fit both in-spec and out-of-spec Picatinny rails and can be adjusted without proprietary tools, making installation simpler across different rifles and carbines.
• 6061-T6 aluminum construction: A CNC-machined aluminum body keeps weight low while providing the rigidity needed for a repeatable prism-sight mount on a working rifle.

About the AD Red Dot Mounts Series

American Defense AD Red Dot Mounts are a dedicated family of optic mounts built for compact sights and prism-style optics used on modern sporting and tactical rifles. Within the company’s wider mount lineup, this series covers footprints for popular optics such as Aimpoint Micro, Trijicon MRO, and other compact sight patterns, giving shooters a purpose-built interface instead of relying on one-size-fits-all solutions. A defining feature across many models is the patented QD Auto Lock lever system, which allows fast removal and reinstallation while accommodating both in-spec and out-of-spec Picatinny rails.

The series is designed around practical fitment and application. Different models are offered for AR-15s, AR pistols, and other weapon platforms, with height options that can include low, co-witness, lower 1/3 co-witness, high, and night-vision configurations depending on the optic. Lever choices also vary, with standard, TAC, and titanium versions available in the range. The overall design philosophy is straightforward: keep the mount compact, repeatable, and easy to adjust in the field while matching the footprint and intended use of the optic it supports.

About the AD mount for Vortex Spitfire 3x, Titanium Lever

The American Defense AD mount for the Vortex Spitfire 3x is a replacement quick-detach base made specifically for the Generation 1 Vortex Spitfire 3x prism optic. That model-specific fit is the main advantage here. Instead of adapting the optic through a more general mount pattern, this base is built around the Spitfire 3x itself, which helps create a cleaner installation and a more secure interface on a Picatinny rail. For shooters using prism optics on AR-platform rifles or similar carbines, that matters because the mount becomes part of the sighting system rather than just an accessory underneath it.

This version uses American Defense’s titanium lever assembly, which trims lever weight while improving strength and corrosion resistance. In practical terms, that gives the mount a lighter, more streamlined quick-detach mechanism that still stands up well to repeated use. The QD Auto Lock system is also adjustable without proprietary tools, so tension can be set with a finger or flat blade screwdriver to suit different rail dimensions. That is especially useful for users running multiple rifles, because the mount is designed to accommodate both in-spec and out-of-spec Picatinny rails.

The body is machined from 6061-T6 aluminum, balancing low weight with the rigidity needed for a repeatable optic mount. With a listed 15.00 mm height and a compact form tailored to the Spitfire 3x, this mount suits shooters who want fast removal, dependable reattachment, and a purpose-built ADM solution for a fixed-magnification prism sight.
