Trijicon TA51 ACOG MIL-STD Rail Flattop Mount

The Trijicon TA51 is the ACOG flattop mount for MIL-STD rails, giving compatible ACOG optics a dedicated rail-mounted base. Trijicon specifies an aluminum housing with a hard coat anodized finish for the mount. The assembly uses Colt-style knob and thumbscrew hardware rather than a lever-type quick-release mechanism.

At 3.5 in long and 4 oz, the TA51 is a compact mounting component rather than a large riser or cantilever base. The important fit check is the ACOG model and the rail interface on the firearm, because the mount is designed around Trijicon's ACOG system. If the mount is being considered for an RX30 application, Trijicon's compatibility requirements should be checked separately rather than assuming the TA51 alone completes that installation.

Compatibility is the priority with this optic mount, especially when similar Trijicon parts differ by only a small dimension or footprint. The Picatinny interface is the main mounting detail to confirm along with the optic footprint. Browse more optics and rangefinders for additional optic mounts, rings, and adapters.
