Primary Arms 30mm PLx Cantilever Mount

• 30 mm cantilever layout: Positions a 30 mm riflescope farther forward on the rail, helping achieve proper eye relief on AR-pattern and other modern rifle setups without crowding the charging handle area.
• 0 MOA alignment: Keeps the optic level with the bore for general-purpose shooting distances, making it a practical choice for carbines and rifles that do not need a built-in long-range elevation bias.
• Aluminium construction: Combines low weight with the rigidity needed for a secure optic interface, so the rifle stays easier to handle without giving up mounting stability.
• Compact 167.00 g weight: Adds less mass than many heavy-duty mounts, which helps preserve rifle balance and reduces unnecessary front-end weight during field carry or repeated positional shooting.
• Fixed tactical mount format: A simple non-QD design reduces extra bulk and moving parts, giving the shooter a straightforward, repeatable mounting solution for a dedicated optic setup.

About the Primary Arms Mounts Series

Primary Arms Mounts covers a broad range of mounting solutions for modern optics, from scope mounts, magnifier mounts, scope rings, and risers to models tailored for red-dot and prism optics. Within the lineup, the series is designed to support different rifle configurations and optic sizes rather than forcing one mounting pattern across every application. The catalog includes options for 1-inch, 30mm, and 34mm tubes, along with mounts built around the M1913 Picatinny interface that remains standard on many tactical and sporting rifles.

A defining trait of the series is its variety of formats. Primary Arms offers cantilever mounts for proper eye-relief placement on AR-style rifles, separate rings for more traditional bolt-action setups, and magnifier mounts with flip-to-side operation for users running a red dot with a magnified secondary optic. The range also spans different product tiers, including CLx, SLx, GLx, and PLx variants, so users can match mount design and construction to the role of the rifle and the level of optic being installed. That makes the series relevant to both practical range use and more demanding tactical optics setups.

About the Primary Arms 30mm PLx Cantilever Mount

The Primary Arms 30mm PLx Cantilever Mount is built for shooters who want a dedicated, stable mounting platform for a 30 mm riflescope on a rifle with a full-length top rail. Its cantilever geometry moves the optic forward compared with conventional rings, which is especially useful on AR-platform rifles where receiver space is limited and correct eye relief often requires extra forward offset. In practical use, that means a more natural head position and better consistency behind the scope.

This model uses a 0 MOA configuration, making it well suited to general-purpose carbines, hunting rifles, and tactical rifles that are zeroed for standard engagement distances rather than set up around extended elevation travel. Because there is no built-in cant, the mount keeps scope setup straightforward and versatile across a wide range of common shooting applications. The aluminium body keeps weight to 167.00 g, which helps maintain rifle balance while still providing the stiffness expected from a one-piece mount.

With a 110.00 mm overall length and a fixed tactical format, the mount is intended for shooters who prefer a simple, repeatable installation over quick-detach complexity. The 0° offset angle and absence of an integrated bubble level keep the design clean and focused on its core task: holding a 30 mm optic securely in the correct position for dependable day-to-day use on a working rifle.

About Primary Arms

Primary Arms Optics was founded in 2008 and is headquartered in Houston, Texas, United States. The company focuses on optics and related equipment for sporting, hunting, and tactical use, with a catalog that includes rifle scopes, prism scopes, red dot sights, mounts, and accessories. In addition to product design and manufacturing, Primary Arms also operates e-commerce, wholesale distribution, and government sales divisions.

The brand is especially well known for the ACSS reticle system, which helped establish its reputation in riflescopes and fighting optics, and for technologies such as AutoLive motion-sensing illumination in compatible optics. Its product families include PLx, GLx, SLx, and CLx, covering different performance tiers and applications. That broad optics background is relevant to mounts like the PLx series, because the company designs mounting solutions to complement the scope and sight systems used on modern rifles.
