Arex Acro P1/P2 Adapter Plate

• ACRO interface conversion: Adapts an Aimpoint ACRO mounting standard sight to an Arex Delta Gen2 optics-ready slide, making it possible to use enclosed-emitter red dots on the pistol platform.
• Metal construction: The metal body provides the rigidity needed to keep the sight interface stable under repeated recoil, which helps preserve mounting security in regular range or duty use.
• Purpose-built fit: Designed specifically for the Arex Delta Gen2, the plate gives a direct, model-matched mounting solution instead of relying on a generic adapter with unnecessary compromise.
• Compact mounting solution: As an adapter plate rather than a bulkier bridge mount, it keeps the optic installation low and tidy, which supports a more natural sight picture and handgun handling.

About the Acro P1/P2 Adapter Plate Series

Adapter plates for optics-ready handguns are a practical part of the modern pistol ecosystem, allowing shooters to match a preferred red dot footprint to a specific slide cut. In the case of the Acro P1/P2 adapter format, the focus is on compatibility with enclosed-emitter pistol optics that use the Aimpoint ACRO mounting standard. This style of interface is especially relevant for users who want the durability and weather resistance associated with enclosed red dot sights.

Within a handgun lineup, these plates serve as the link between the pistol’s factory optics-ready system and the chosen optic footprint. Their design priority is usually secure alignment, repeatable positioning and low-profile installation, because those factors influence how naturally the dot presents and how confidently the optic stays in place during recoil. For practical shooting, defensive use and general range work, a dedicated plate system offers a cleaner and more dependable solution than improvised mounting methods.

About the Arex Acro P1/P2 Adapter Plate

The Arex Acro P1/P2 Adapter Plate is made for shooters who want to mount a red dot with the Aimpoint ACRO mounting standard on an Arex Delta Gen2 optics-ready pistol. Its role is straightforward but important: it converts the slide interface so the optic and handgun work together as a properly matched system. That matters in practice because a correct footprint match affects not only whether the sight fits, but also how securely it sits and how consistently it returns to position under recoil.

The use of a metal construction is particularly relevant on a reciprocating pistol slide, where the adapter must cope with repeated impact forces while maintaining a stable mounting surface. A rigid plate helps support reliable optic retention and gives the shooter more confidence that the sight remains properly seated through training sessions and regular carry use. Because this is a dedicated adapter for the Delta Gen2, it is also a cleaner choice for users who want an enclosed-emitter optic without moving to a different handgun platform.

In practical terms, this adapter plate is best suited to shooters building a modern handgun setup around the ACRO footprint. It keeps the installation focused on compatibility and mechanical security, which are the two things that matter most when adding a pistol red dot to an optics-ready slide.

About Arex

AREX was founded in 1994 by Ivan Kralj and developed from a tool-industry business into a defense-sector manufacturer. Based in Šentjernej, Slovenia, the company produces self-loading pistols, training ammunition, firearm components and barrels, giving it a broad manufacturing base that is closely tied to practical firearms use.

Within its handgun range, REX ZERO 1 and DELTA are the best-known pistol families, and some Delta Gen.2 variants use optics-ready slides with interchangeable mounting plates. That background is directly relevant here: AREX is not simply making a generic accessory, but a mounting component intended to integrate with its own pistol platform and optics-ready system.
