The Battle Arms Development Buffer Tube (brand part number AR15RE-MIL-6C) is a Black anodized aluminum receiver extension built to fit the AR15, M16, M4, AR9, and AR10 platforms. Battle Arms Development machines it to mil-spec dimensions, giving builders a broadly compatible buffer tube that works across both direct-impingement rifle-caliber builds and pistol-caliber AR9 setups without hunting down a platform-specific part. It’s a straightforward, correctly toleranced foundation for a stock or brace installation.
