The Battle Arms Development Enhanced Modular Magazine Release (BAD-EMMR) in Large is a precision-engineered aluminum mag release built for shooters who want reliable, ergonomic control without compromise. Machined from 7075-T6 billet aluminum and made in the USA, this large-format release features BAD's patent-pending three-sided dovetail attachment system that locks the interchangeable finger pad in place with genuine strength while keeping the profile clean and uncluttered. Whether you're running an AR-15 or working with a precision rifle platform, the large size gives you a commanding grip surface that won't force you to shift your hand position or break your shooting stance.
The three-sided dovetail design is the mechanical heart here—it distributes force across three planes instead of relying on a single fastener, which translates to a release that stays put through hard use and repeated cycling. The interchangeable finger pads let you dial in the ergonomics that work best for your hand and shooting style, and the low-profile, lightweight construction keeps your rifle balanced without adding unnecessary bulk.
One honest note: BAD advises that due to receiver-to-receiver variation in AR308 billet platforms, compatibility may be limited. If you're building on an AR308, verify fitment with your specific receiver before ordering. For standard AR-15 platforms, this is a no-compromise choice for shooters serious about controls that work as hard as they do.
