Battle Arms Development Medium Enhanced Modular Mag Release | Raw

The Battle Arms Development Medium Enhanced Modular Mag Release in Raw is a bare billet aluminum control that gives builders a clean, uncoated canvas and a serious ergonomic upgrade in one part. Sold as the BAD-EMMR Medium, it replaces the small mil-spec button with a larger, better contoured pad that speeds up every reload. The natural raw aluminum finish is ideal for anyone planning to Cerakote, anodize, or simply run the honest look of machined metal. It is a favorite of hands on AR builders who like to finish parts their own way.

What the Battle Arms Development Medium Release Is and Who It Is For

The Raw version delivers the same middle ground geometry that makes the Battle Arms Development Medium so popular, offering more pad than mil-spec without the oversized feel of full competition parts. It suits precision builds, custom coated rifles, and any project where the owner wants control over the final finish.

Because it ships uncoated, it is the go to choice for shops and hobbyists running a color matched Cerakote job across the whole rifle. Shooters who prize a raw, industrial aesthetic will also appreciate the way machined aluminum catches the light.

Key Features

• Machined from billet 7075-T6 aluminum for strength with minimal added weight
• Raw, uncoated surface that is ready for Cerakote, anodizing, or a natural finish
• Medium profile pad that enlarges the control surface for faster reloads
• Direct replacement for standard AR-15 and AR-10 magazine releases
• Textured face for positive engagement with bare or gloved hands
• Clean machined lines that show off custom coatings beautifully

Specifications and Build Quality

This Battle Arms Development Medium release starts as a block of billet 7075-T6 aluminum before it is CNC machined to final shape. That alloy is chosen for its high yield strength, so even a raw, uncoated part resists deformation from years of hard reloads.

With no finish applied, the surface takes coatings exceptionally well after proper prep and degreasing. Builders get a true, dimensionally accurate base to work from rather than fighting an existing layer of anodizing.

Installation, Compatibility, and Care

Installation is identical to a standard magazine release, dropping into mil-spec lowers with the usual catch, spring, and button arrangement. No modification to the receiver is required, which keeps the build reversible and simple.

Because the aluminum is bare, apply a light coat of oil to exposed surfaces if you plan to run it uncoated, since raw metal can spot in humid storage. Once Cerakoted or anodized, it becomes as weather resistant as any finished control.

Match it to the rest of your project by exploring more AR parts and upgrades that can all be coated together in one batch.

For the builder planning a custom finish, this raw release is the ideal blank canvas. Machined aluminum accepts Cerakote evenly once properly degreased, letting you match the control precisely to a receiver set or handguard with no factory anodizing to strip or work around. The color you apply is the color you get.

Even left bare, the control delivers the same faster, more positive reloads as its finished siblings, and many builders prefer the honest, industrial look of machined metal against a black or FDE lower. Just keep a light film of oil on uncoated aluminum in humid storage, and it will serve reliably for years whether you coat it or run it raw. That flexibility is why raw parts remain a favorite among shops and hobbyists who finish every component in a single matched batch.

The Battle Arms Development Medium release in Raw hands the finishing decision back to the builder without giving up an ounce of function. Coat it, blend it, or run it bare and enjoy the faster reloads either way. Ships direct to your door, no FFL required.
