Magpul MAG402-BLK MOE Illumination Kit - 4 Piece Black Polymer Tactical Accessory

The Magpul MAG402-BLK MOE Illumination Kit is a purpose-built mounting system that lets you add a weapon light to your AR-platform rifle without surrendering handguard real estate or clean lines. If you're running a MOE handguard and want the tactical advantage of onboard illumination, this four-piece kit gives you multiple mounting options to suit your rifle setup and light choice. It's engineered in Magpul's characteristic tough polymer and includes all the hardware you need for a straightforward install.

Tactical shooters, home-defense builders, and hunters who want reliable night-time capability appreciate kits like this because they consolidate everything in one package. You're not hunting through bins for the right rail section, pressure switch mount, or obscure fasteners—Magpul thought it through. The kit plays well with standard Picatinny-compatible lights, so you're not locked into a single brand or model. Even if you're running a Bushmaster ACR, this kit is confirmed to fit, expanding its utility beyond the standard MOE platform.

What makes this different from bolting a light straight to your receiver or gas tube is the handguard integration: it keeps your light positioned predictably, reduces potential snag points, and maintains the ergonomics of your fore-end. Whether you're setting up for low-light tactical training, nighttime property checks, or backup home-defense capability, a well-mounted weapon light is a serious force multiplier.
