Primary Arms 30mm PLx Cantilever Mount, 20 MOA

• 20 MOA Inclination: Built-in forward cant preserves more of a scope’s internal elevation travel, which helps long-range rifles keep useful adjustment in reserve for distant targets.
• 30 mm Cantilever Layout: The cantilever design pushes the optic forward for better eye-relief positioning on AR-pattern and other modern rifles, while the 30 mm ring size fits a wide range of tactical and hunting optics.
• PLx-Grade Construction: The mount uses a stronger, more rigid build than basic entry-level mounts, helping the optic stay aligned under recoil and repeated handling.
• Lightweight Aluminum Body: At 167.00 g, the mount adds useful strength without excessive weight, which matters on rifles carried for long periods or used in dynamic shooting.
• Fixed, Repeatable Interface: A non-QD cross-bolt style mount keeps the setup simple and solid, making it well suited to rifles where consistent zero retention matters more than rapid removal.

About the Primary Arms Mounts Series

Primary Arms Mounts covers a broad range of optic interfaces for modern rifles and carbines, from scope mounts and rings to magnifier mounts and risers. Within the lineup, the series is designed to support different optic sizes and use cases rather than forcing one mounting solution onto every rifle. The catalog includes options for 1-inch, 30 mm, and 34 mm tubes, along with mounts for red-dot and prism optics, which makes the series relevant to both general-purpose sporting rifles and more specialized tactical setups.

A defining trait of the range is its practical approach to fit and function. Cantilever mounts are offered for shooters who need proper eye-relief placement on rifles with limited receiver space, while other designs focus on compactness, quick handling, or compatibility with the M1913 Picatinny interface. Primary Arms also separates the line into tiers such as CLx, SLx, GLx, and PLx, allowing users to choose between straightforward utility and more refined construction. Across the series, the emphasis stays on secure optic alignment, compatibility with common platforms, and mounting geometry that supports real field use rather than bench-only setups.

About the Primary Arms 30mm PLx Cantilever Mount, 20 MOA

The Primary Arms 30mm PLx Cantilever Mount, 20 MOA is built for shooters who want a rigid scope mount with geometry suited to longer-range work. Its defining feature is the 20 MOA inclination, which angles the optic slightly downward relative to the bore so the scope retains more upward elevation adjustment. In practice, that matters when a rifle and optic combination is expected to stretch beyond ordinary zero distances, because it helps preserve turret travel for dialing at range.

The 30 mm ring diameter makes this mount compatible with many popular riflescopes, while the cantilever format improves scope placement on rifles where the receiver alone does not provide enough room for correct eye relief. That makes it especially useful on AR-platform rifles and similar setups where optic position has to balance charging-handle clearance, head position, and shooting comfort. With 110.00 mm overall length and a fixed, non-offset layout, it keeps the optic centered and straightforward to install.

Its aluminium construction keeps weight to 167.00 g, which is light enough for practical field rifles yet substantial enough for a stable interface between scope and rail. The absence of a built-in bubble level keeps the mount streamlined for users who prefer a simpler profile or already run a separate leveling accessory. Overall, this is a purpose-driven tactical scope mount for shooters who need secure 30 mm support and built-in cant for precision-oriented rifle setups.

About Primary Arms

Primary Arms Optics was founded in 2008 and is headquartered in Houston, Texas, United States. The company focuses on shooting optics and related equipment, with a product range that includes rifle scopes, prism scopes, red dot sights, mounts, and accessories. Its lineup is organized into families such as PLx, GLx, SLx, and CLx, giving the brand a structured approach across different performance tiers and applications.

Primary Arms is especially known for developing the ACSS reticle system, a design approach intended to combine aiming, ranging, and hold references in a faster, more intuitive format than a basic crosshair. The company also uses technologies such as AutoLive motion-sensing illumination in relevant optics. Alongside product design and manufacturing, Primary Arms operates e-commerce, wholesale distribution, and government sales divisions, which reflects its strong focus on practical rifle optics and mounting solutions for civilian, professional, and agency use.
