Primary Arms Deluxe Extended Scope Mount - 30mm, 2.28in Clearance for 1913 Rails

The Primary Arms Deluxe Extended Scope Mount for 30mm optics blends rugged construction with thoughtful geometry to help you set up a reliable field-ready sight line. Designed to fit 1913 Picatinny and flat-top rails, this mount keeps your optics square and consistent across cycles of use and removal. The aluminum is machined with a durable anodized finish to resist wear in varied shooting environments. When paired with a 30mm scope, you gain predictable eye relief and repeatable alignment, even after removing and reinstalling the optic.

Key features

• 30mm scope tube compatibility for a wide range of variable power optics.
• Suitable for 1913 Picatinny and similar flat-top rails for versatile mounting options.
• Machined aluminum construction with a resilient anodized finish for everyday field use.
• 2.28 inches of clearance between rings to accommodate larger objective lenses and tall eyepieces.
• Centers the scope tube about 1.5 inches above the rail for improved sight lines and eye relief.

With precise machining and a sturdy clamping surface, the mount helps maintain alignment during dynamic shooting scenarios. The added height and clearance can ease optic swaps while preserving a reliable zero, depending on your rifle setup and chosen optic.

Typical use cases

• AR-style platforms and other flat-top rails that benefit from extra space for big objective lenses.
• Backcountry or range days where a reliable, durable mount contributes to quicker starts and stable aiming.
• Optic upgrades requiring a consistent, repeatable mounting footprint across different rifles within a family.

Note that performance can vary with optic type, rail condition, and mounting torque. This description highlights the mount geometry and materials that influence installation and use, rather than promising specific results.
