Offset Plate, Holosun 407k & 507k For 1.9''- 2.2'' Scope Mount

The Offset Plate for Holosun 407K & 507K designed for 1.9″–2.2″ scope mounts solves a critical optics integration challenge faced by tactical operators and law enforcement professionals. When mounting compact red dots like the Holosun 407K or 507K on standard rifle scope mounts, co-witnessing and sight-line optimization become problematic without proper offset geometry. This Arisaka Defense plate eliminates that gap by providing a precision-engineered interface that positions your micro red dot at the correct height and angle relative to your primary optic or iron sights, ensuring rapid target acquisition and redundancy in the field.

Engineered for scope mounts in the 1.9″ to 2.2″ mounting width range, this offset plate accommodates the dimensional variance found across popular tactical and hunting rifle setups. The plate is machined to exacting tolerances and designed to maintain zero shift through heavy recoil cycles and field deployment, critical for duty weapons and precision platforms alike. At just 0.17 lbs, it adds negligible weight while preserving the structural integrity of your rail system. The precision fit ensures that your Holosun 407K or 507K maintains repeatable zero without the cant or drift that can occur with improvised or undersized mounting solutions.

This offset plate is ideal for shooters running dual-optic configurations on carbines, patrol rifles, and precision rifles where space constraints or co-witness requirements demand compact red dot placement above or offset from the primary sight picture. Law enforcement and military units benefit from the redundancy provided by a backup aiming system that doesn't compromise sight picture clarity or response time. Installation is straightforward for users familiar with picatinny rail systems; the plate interfaces directly with your existing scope mount, requiring no permanent modifications to your firearm. Verify your scope mount width falls within the 1.9″–2.2″ specification before purchase to ensure proper fit and function.
