Primary Arms High Cantilever 30mm Mount – Lower 1/3 Cowitness

Description

Primary Arms High Cantilever 30mm Mount

The High Cantilever Mount will raise most 30 MM tube red dot sights to allow for a lower 1/3rd cowitness. A lower 1/3rd cowitness places the red dot in the bottom part of the scope tube when aiming down the iron sights. This allows a less obstructed view of the scope tube when using the red dot instead of the iron sights. If utilizing a red dot magnifier, pair up with standard height flip to side mount such as PAMQF – 01 or PAQDMQF – 01. This tough mount features a 1 year warranty.

This high cantilever configuration is particularly beneficial for those running longer barrels or bulky rail systems, as it provides additional space for the optic without compromising stability. The mount’s lower 1/3 co-witness height is specifically tailored for AR-style platforms, enabling shooters to use a backup iron sight (BUIS) while still maintaining an unobstructed view through the optic. With this setup, the red dot sits just above the iron sights, allowing for quick transition between optic and irons without the need to adjust head position or re-align the sight picture. Built from robust, aircraft-grade aluminum and finished with a durable coating, the mount is designed to withstand recoil, harsh environmental conditions, and consistent use at the range or in the field.

The clamp-on interface ensures a rock-solid attachment to standard Picatinny rails, and the precision-machined design maintains optic alignment and repeatability even after repeated removal and reinstallation. Overall, the Primary Arms High Cantilever 30mm Mount is an excellent choice for shooters seeking a reliable, versatile mount that supports both modern optics and traditional iron sights, offering a perfect balance of height, stability, and practicality for tactical, competition, or everyday shooting applications.
