The Battle Arms Development Large Enhanced Modular Mag Release in raw offers oversized reload performance with a natural, bare aluminum finish for AR-15 and AR-10 rifles. This Battle Arms Development Large release, the BAD-EMMR Large, is precision machined from billet 7075-T6 aluminum for a strong, lightweight, aggressive control surface. The raw finish shows off the machined metal and makes an ideal base for custom Cerakote or anodizing. It is the choice for builders who want big-button speed and the freedom to finish the part their own way.
Some builders want to control every detail of their rifle’s finish, right down to the mag release. Starting with a raw, uncoated part gives you a clean base and skips the hassle of stripping an existing color.

Specs and Build Quality
The raw variant uses the same billet 7075-T6 aluminum as the coated versions, just without a color coating, so the machined surfaces are on full display. That makes the Battle Arms Development Large release an easy foundation for a custom finish, since nothing has to be removed first.
The enlarged control surface still delivers the same big, forgiving target for fast, positive mag drops. Whether you leave it bare or finish it to match a build, the oversized performance stays exactly the same. The bare aluminum also accepts coatings evenly, which helps a home finish come out clean and consistent.
Practical Use, Care, and Compatibility
Run it raw for a clean bare-metal accent, or send it out for Cerakote to match your color scheme. Either way, the large control surface keeps your reloads quick and positive under speed.
Bare aluminum can pick up marks, so a light wipe keeps it fresh, or seal it with your finish of choice. It fits AR-15 and AR-10 platforms and pairs with the customizable parts in our Parts and Upgrades collection. Machined by Battle Arms Development, the raw BAD-EMMR Large is a builder’s blank slate with oversized speed.
Installation and Finishing Notes
The large release installs like any drop-in button. Depress the magazine catch, remove the factory part, install the raw replacement, and confirm a loaded magazine seats and drops free. Watch the small spring so it does not vanish into the bench.
If you plan to coat it, the bare aluminum accepts Cerakote or anodizing evenly, with no existing finish to strip first. Left raw, the machined surfaces give the oversized control an honest, industrial look that suits a bare-metal build.
Since bare aluminum shows fingerprints and marks, wipe it down now and then or seal it with your finish of choice. Either way, the large surface keeps reloads quick and positive exactly like the coated versions.
Finish it your way and reload faster with the Battle Arms Development Large Enhanced Modular Mag Release in raw. It is oversized speed on a blank canvas. Ships direct to your door, no FFL required.
