Primary Arms 34mm PLx Cantilever Mount

• 34 mm cantilever fit: Built for 34 mm scope tubes, this mount gives larger tactical and precision optics a secure interface while moving the scope forward for a more practical eye-relief position on AR-style rifles.
• 0 MOA alignment: The flat, non-inclined design keeps the optic centered without added cant, which suits general-purpose carbines and rifles where a straightforward zero and familiar sight picture matter more than extended elevation bias.
• Aluminium construction: The aluminium body keeps weight to 167.00 g, helping maintain a balanced rifle while still providing the rigidity needed to hold a scope firmly under regular field and range use.
• Compact one-piece format: At 110.00 mm in length, the one-piece cantilever layout simplifies installation and keeps ring alignment consistent, reducing setup time compared with separate rings.
• PLx-series positioning: As part of the Primary Arms Mounts range, this model is aimed at shooters who want a cleaner, purpose-built mounting solution for modern sporting and tactical rifle setups.

About the Primary Arms Mounts Series

Primary Arms Mounts covers a broad range of mounting solutions for scopes, magnifiers, red-dot optics, scope rings, and risers. Within the lineup, the series is designed to support everything from compact carbine optics to larger precision-oriented scopes, with options for 1-inch, 30 mm, and 34 mm tubes. That breadth makes the family relevant to both general shooting setups and more specialized tactical optics configurations.

The series includes CLx, SLx, GLx, and PLx variants, giving shooters different levels of refinement and intended use within the same overall catalog. Primary Arms also offers both cross-bolt and thumb-screw release configurations, along with cantilever mounts and separate rings, so the mounting style can be matched to the rifle and optic rather than forced into one format. M1913 Picatinny compatibility is a key part of the lineup, reflecting the practical focus on modern rifle platforms. Across the range, the design philosophy is straightforward: secure optic retention, sensible geometry, and mounting options that fit common sporting, hunting, and tactical rifle applications.

About the Primary Arms 34mm PLx Cantilever Mount

The Primary Arms 34mm PLx Cantilever Mount is a fixed one-piece mount for riflescopes with a 34 mm tube diameter, aimed at shooters using larger modern optics on rifles that benefit from a forward-mounted scope position. The cantilever layout helps place the optic where eye relief is easier to achieve on AR-pattern and similar platforms, which is especially useful when mounting scopes with generous magnification ranges or larger eyepieces.

This version uses a 0 MOA configuration with 0° offset angle, making it a practical choice for shooters who want a neutral mounting base rather than an inclined setup. That suits general-purpose rifle builds, duty-style carbines, and many hunting or target rifles where a simple zeroing process and conventional optic alignment are preferred. The one-piece design also helps keep both rings in consistent alignment, which supports reliable scope installation and reduces the variables that can come with separate rings.

The mount body is made from aluminium, balancing rigidity with manageable weight at 167.00 g. With an overall length of 110.00 mm, it remains compact enough not to add unnecessary bulk to the rifle. The absence of an integrated bubble level keeps the profile clean and uncomplicated, which will appeal to users who prefer a lighter, simpler mounting solution focused on secure scope placement rather than added accessories.

About Primary Arms

Primary Arms Optics was founded in 2008 and is headquartered in Houston, Texas. The company focuses on rifle scopes, prism scopes, red dot sights, mounts, and related accessories, giving it a strong presence in the modern sporting, hunting, and tactical optics market. Its product families include PLx, GLx, SLx, and CLx, which organize the lineup by intended use and feature level.

Primary Arms is also known for developing the ACSS reticle system, a design approach that combines aiming, ranging, and hold references in a more application-specific format than a basic crosshair. In addition to optics design, the company operates e-commerce, wholesale distribution, and government sales divisions. That broader structure reflects a brand with practical experience in how optics and mounting systems are selected and used across civilian, professional, and agency markets.
