Vortex Precision QR Extended Cantilever 30mm mount

• Quick-release lever system: Removes and reinstalls the mount without tools, making it practical for rifles that alternate between optics or need fast transport and maintenance.
• Extended cantilever layout: Pushes the scope forward to achieve proper eye relief and a natural head position on flat-top rifles, especially with AR-style platforms.
• One-piece 30 mm mount: Keeps both rings aligned in a single structure, which simplifies installation and helps maintain a stable interface between scope and rifle.
• Aluminium construction: Reduces unnecessary weight while still providing the rigidity needed for hard field use, competition setups, and duty carbines.
• 25.00 mm base height with 51.0 mm extension: Combines useful optic clearance with forward offset, helping larger eyepieces and modern shooting positions fit more naturally.

About the Vortex Cantilever Mounts Series

Vortex Cantilever Mounts are built to solve a common mounting problem on modern rifles: getting a riflescope far enough forward for correct eye relief without resorting to improvised ring placement. In the Vortex lineup, the series spans Sport, Pro, and Precision variants, giving shooters options from straightforward range use to more demanding competition and duty roles. The family is particularly well suited to flat-top AR-style rifles with Picatinny rails, where scope position has a direct effect on comfort, speed, and consistency.

Across the range, the defining idea is a one-piece cantilever design that combines ring alignment, forward offset, and repeatable rail attachment in a compact unit. Depending on the model, the series includes fits for 1 inch, 30 mm, or 34 mm scope tubes, with some versions adding quick-release capability or a 20 MOA cant for applications that demand more elevation travel. Within the family, the Precision Extended Cantilever models are aimed at competition, home-defense, and duty use, where secure mounting, efficient eye position, and dependable handling matter as much as raw strength.

About the Vortex Precision QR Extended Cantilever 30mm mount

The Vortex Precision QR Extended Cantilever 30mm mount is a purpose-built solution for shooters who want the speed of a quick-release mount without giving up the forward scope placement needed on AR-pattern rifles and other Picatinny-equipped platforms. Its extended cantilever geometry moves the optic ahead of the receiver, which helps establish proper eye relief and a more relaxed, repeatable cheek position. In practice, that means faster target acquisition and less compromise in shooting posture when using low-power variable optics or other 30 mm riflescopes.

This mount uses a one-piece aluminium body, a layout that keeps both rings in fixed alignment while reducing the number of separate parts in the mounting system. That is useful not only during installation, but also for maintaining a stable interface under repeated handling. The 30 mm ring size makes it suitable for a wide range of modern riflescopes, while the 25.00 mm base height and 51.0 mm extension help create the clearance and forward positioning commonly needed on tactical optics and sporting carbines.

Vortex lists this model at 8.9 oz with a 1.45 inches (37mm) center scope height, placing it in a configuration that balances strength, usable optic height, and practical handling. The quick-release system is especially useful for rifles that may alternate between optics, require compact transport, or need rapid access to the rail without a full remounting process.

About Vortex

Vortex traces its roots to a Wild Birds Unlimited store opened by the Hamilton family in Madison, Wisconsin, in 1986. The brand entered the sport optics market in 2002 and is now headquartered in Barneveld, Wisconsin, where it operates as an employee-owned company. Vortex focuses on optics for hunting, shooting, and outdoor use, with product lines that include riflescopes, binoculars, spotting scopes, laser rangefinders, and red dots.

The company is also known for developing supporting tools around its optics, including ballistic solutions powered by GeoBallistics technology. Its presence extends beyond the commercial market: in 2022, Vortex was selected to produce and deliver fire-control systems for the U.S. Army’s Next Generation Squad Weapons program. In practical terms, that background helps explain why Vortex mounting products emphasize straightforward function, compatibility with modern rifle platforms, and designs that support both sporting and professional applications.
