SPECPRECISION Glock MOS to ACRO Footprint Adapter Plate

SPECPRECISION Glock MOS to ACRO Adapter Plate

The SPECPRECISION Glock MOS to ACRO Adapter Plate is a precision-machined optic adapter designed to convert a compatible standard GLOCK MOS slide interface into an ACRO-compatible mounting footprint.

It allows users to install Aimpoint ACRO series optics as well as other enclosed red dot sights that use a compatible ACRO-style or ACRO-compatible mounting interface.

Machined from 6061-T6 aviation-grade aluminum, the adapter combines precise fitment, low weight and a compact profile. Its black anodized surface provides a clean matte appearance while helping protect the aluminum surface during regular use.

GLOCK MOS to ACRO Footprint Conversion

This adapter creates a mounting interface between a compatible standard GLOCK MOS slide and an ACRO-footprint red dot sight.

Instead of being limited to one specific optic model, the adapter can be used with a variety of enclosed red dot sights that share a compatible ACRO-style mounting interface.

This makes it a practical solution for users looking for a Glock MOS ACRO adapter plate, MOS to ACRO adapter, or Glock MOS enclosed red dot adapter.

Compatible GLOCK MOS Models

Designed for compatible standard full-width GLOCK MOS configurations, including:

• GLOCK G17 MOS
• GLOCK G19 MOS
• GLOCK G20 MOS
• GLOCK G21 MOS
• GLOCK G22 MOS
• GLOCK G23 MOS
• GLOCK G34 MOS
• GLOCK G35 MOS
• GLOCK G40 MOS
• GLOCK G41 MOS
• GLOCK G45 MOS
• GLOCK G47 MOS

Important: Compatibility is based on the mounting interface and slide configuration. Always verify that your slide uses the compatible standard GLOCK MOS mounting system before ordering.

Not Compatible With Slimline MOS

This adapter is not compatible with GLOCK Slimline MOS models, including:

• GLOCK G43X MOS
• GLOCK G48 MOS

Slimline MOS models use a different optic mounting configuration and should not be used with this adapter.

Compatible With ACRO Footprint Red Dot Sights

The upper mounting interface is designed around an ACRO-compatible footprint.

It can accept Aimpoint ACRO series optics and other enclosed red dot sights that use a compatible ACRO-style mounting system.

Compatible examples include:

• Aimpoint ACRO P-1
• Aimpoint ACRO P-2
• SPECOPTICS Sentinel V3 Solar Enclosed Multi-Reticle 1x24mm Red Dot Sight
• SPECOPTICS NEO-E2 3.5MOA Enclosed Red Dot Sight
• Other red dot sights using a compatible ACRO-style mounting interface

The SPECOPTICS Sentinel V3 uses an ACRO footprint, while the SPECOPTICS NEO-E2 uses an ACRO-style / ACRO-compatible mounting interface, making both suitable optic options for this adapter.

6061-T6 Aviation-Grade Aluminum

The adapter plate is CNC machined from 6061-T6 aviation-grade aluminum for a balance of structural strength, precision and low weight.

At only 15.6 g / 0.55 oz, the adapter adds minimal additional weight to the optic setup.

Black Anodized Finish

The aluminum surface features a black anodized finish that provides a clean, low-profile appearance and additional surface protection.

Compact Low-Profile Design

With overall dimensions of only 48.7 × 27.5 × 5.95 mm / 1.917 × 1.083 × 0.234 in, the adapter maintains a compact mounting profile while providing the required interface between the MOS slide and compatible ACRO-style optic.

Easy Installation

Remove the existing MOS cover plate, position the SPECPRECISION adapter on the compatible MOS interface, and secure it using the supplied mounting screws.

Once the adapter is properly installed, mount the compatible ACRO-footprint optic according to the optic manufacturer's installation instructions.

Included mounting screws: M3 × 0.5 × 5 mm

Frequently Asked Questions

What is a Glock MOS to ACRO adapter plate?

A Glock MOS to ACRO adapter plate converts a compatible standard GLOCK MOS optic mounting interface into an ACRO-compatible footprint, allowing compatible ACRO-style enclosed red dot sights to be installed.

Is this adapter only compatible with Aimpoint ACRO optics?

No. It is designed around an ACRO-compatible mounting footprint. In addition to compatible Aimpoint ACRO optics, it can also be used with other red dot sights that use a compatible ACRO-style mounting interface.

Does the adapter work with the SPECOPTICS Sentinel V3?

Yes. The SPECOPTICS Sentinel V3 Solar Enclosed Multi-Reticle 1x24mm Red Dot Sight uses an ACRO footprint and is compatible with this adapter when the adapter is installed on a compatible standard GLOCK MOS slide.

Does it work with the SPECOPTICS NEO-E2?

Yes. The SPECOPTICS NEO-E2 3.5MOA Enclosed Red Dot Sight uses an ACRO-style / ACRO-compatible mounting interface and is a suitable optic option for this adapter.

Does this adapter fit the G43X MOS?

No. The G43X MOS is a Slimline MOS model and uses a different mounting configuration.

Does this adapter fit the G48 MOS?

No. The G48 MOS is also part of the Slimline MOS family and is not compatible with this adapter.

What material is the adapter made from?

The adapter is CNC machined from 6061-T6 aviation-grade aluminum and features a black anodized surface finish.

How much does the Glock MOS to ACRO adapter weigh?
