EMM M4 / AR15 Mid-Cap Magazine by Arcturus

This high-quality mid-cap magazine by Arcturus is designed for AR15, SR16, MK16 and other rifles such as M4, M16, MK18, and 416 (AR-series). Featuring a high-quality metal body with a QPQ surface finish and a realistic STANAG 5.56 design, it provides excellent impact resistance and long-term durability. The magazine is equipped with a modular internal system (EMM), allowing for easy maintenance and cleaning. Another advantage is the ability to quickly replace the outer shell with optional variants.
A unique feature is the ability to switch between 30 rounds (Real-Cap) and 130 rounds (Mid-Cap), making it ideal for both realism enthusiasts and Mil-Sim players, as well as those who prefer a higher capacity for less frequent reloading. To ensure smooth BB feeding, the magazine is equipped with a prolonged BB follower, minimizing wasted ammo, meaning it will feed every last BB in the magazine. A speed loader is required for refilling (not included).
