for Mossberg 940 JM Pro - 2 MOA, Compact, Aircraft Aluminum

ADE RD3-021 “NUWA” — 2 MOA Red Dot (FDE / Flat Dark Earth)

Overview
The ADE RD3-021 NUWA is a compact, ultra-light RMS/RMSc-footprint red dot with a top-loading battery — the industry’s first design that lets you change the battery without removing the sight, so you don’t have to re-zero or waste ammo. Built from hard-coated aircraft aluminum with multi-coated glass, the NUWA delivers excellent durability and optical clarity versus polymer-bodied alternatives.

Key Features

• 2 MOA red dot for precise aiming

• Top-loading battery system (change the battery without removing the sight)

• Manual on/off and brightness control: press-and-hold 2s to power on/off; tap to cycle brightness levels

• Integrated rear “iron-sight curve” with two white dots for co-witnessing / backup sighting

• Hard-coated aircraft aluminum body and multi-coated glass lens

• Ultra-light: ~15.5 g (0.55 oz)

• Size: 1.5" L × 0.88" W × 0.89" H

Mounting & Screws

• The NUWA ships with a few common screw sets (for the models listed above), but not all pistols use the same screw length/type. Manufacturers sometimes specify proprietary screws for their optic cuts. If your pistol’s screws are different, you may need to obtain the correct screws locally (hardware stores such as ACE Hardware often carry the right sizes). Contact your pistol manufacturer for exact screw specs if unsure.

Co-Witnessing / Non-Optics-Ready Pistols
For pistols that require an optic plate/adapter (i.e., non-optics-ready slides), ADE designed the NUWA with a rear white-dot / iron-sight curve so the rear of the NUWA can function as a backup rear sight — enabling co-witnessing with many full-size pistols once the proper adapter/plate is installed.
