Armaspec B2 Extended Skeletonized Magazine Release The Armaspec B2 is a lightweight, extended magazine release designed to improve reload efficiency and ergonomics on AR-15 and AR-10 platforms. Its skeletonized design adds surface area while reducing weight, allowing for faster, easier magazine drops without changing grip position. Made from durable aircraft-grade aluminum with a hardcoat anodized finish, the B2 is compatible with both 5.56/.223 and 7.62/.308 receivers. Features a serrated paddle for secure contact, drop-in installation, and ambidextrous usability when paired with mirrored setups. Ideal for duty or competition use.
