The Battle Arms Development Large Enhanced Modular Mag Release in blue combines oversized reload performance with a bold color accent 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 light, strong, aggressive control surface. The blue anodized finish makes the enlarged button a standout feature on two-tone and color-matched builds. It pairs the fastest reloads with a look that shows off your attention to detail.
When you go with an oversized release, it becomes a visual focal point on the lower, so the color matters. Blue turns that big control into a deliberate design element rather than an afterthought.
What the Battle Arms Development Large Enhanced Mag Release Is and Who It Is For
This is an oversized, modular magazine release with a large control surface, finished in blue for shooters who color-coordinate their rifles. It is built for those who want the speed of a big button and the style of a matched accent theme.
Competition and custom builders search for oversized AR-15 magazine releases to shave time off reloads, and the blue BAD-EMMR Large lets them do it with flair. If your build already runs blue accents, this release completes the set. It is speed and style in one part.

Specs and Build Quality
The blue anodized finish is applied over billet 7075-T6 aluminum, so the color is durable and the oversized button underneath is genuinely strong. The Battle Arms Development Large release carries an aggressive profile without meaningful added weight, keeping the rifle balanced.
The enlarged control surface is the functional centerpiece, giving your trigger finger a big, forgiving target for lightning-fast mag drops. In blue, that performance comes wrapped in a finish that makes a coordinated build look intentional and sharp. Anodizing bonds the color into the aluminum, so it resists the chips and scratches a painted button would pick up.
Practical Use, Care, and Compatibility
On the clock, the large surface means fewer missed releases and cleaner reloads, and the blue finish ties the control into a matched color scheme. Pair it with a blue safety and pins for a fully coordinated accent theme.
Keep the button and spring clean and function-check after installation. It fits AR-15 and AR-10 platforms and coordinates with the color-matched parts in our Parts and Upgrades collection. Machined by Battle Arms Development, the blue BAD-EMMR Large pairs speed with standout style.
Installation and Field Notes
The oversized button installs with no permanent modification. Depress the magazine catch, unthread the factory button, install the large replacement, and confirm a loaded magazine seats and drops free before live fire. Mind the small spring during the swap.
On the clock, the large surface becomes automatic within a magazine or two, and reloads start to feel effortless. The blue finish keeps the control tied into a coordinated color scheme rather than standing out as an afterthought.
Pair it with a matching blue safety, pins, or catch for a cohesive two-tone build. The anodized color is bonded into the aluminum, so it resists chips and scratches through heavy handling, cleaning, and years of range time.
Reload fast and build bold with the Battle Arms Development Large Enhanced Modular Mag Release in blue. It is the oversized control that also makes a statement. Ships direct to your door, no FFL required.
