Tyrant CNC Magazine Extension Features The Tyrant CNC Magazine Extension is CNC machined from T6061 aerospace grade aluminum giving the part the strength to handle repeated insertion and removal without wearing out. A bead blasting and hardcoat anodizing process finishes the extension in black protecting the aluminum from corrosion while keeping the surface consistent with the rest of the Echelon s finish. Designed specifically for the Springfield Armory Echelon s 15 and 17 round magazines the extension adds a full 5 rounds of 9mm capacity to either magazine. That added capacity can matter for competition shooters or anyone who wants fewer reloads during a range session. Installation requires no tools so shooters can add the extension to their magazines in minutes rather than scheduling a trip to a gunsmith. NoBak spring plunger technology keeps the base pad securely attached to the magazine body preventing it from loosening or separating under recoil and normal handling. Because the extension is purpose built for the Echelon platform it maintains the magazine s reliable feeding and function rather than compromising it for extra capacity. The Tyrant CNC Magazine Extension is available for sale at GrabAGun for Springfield Armory Echelon owners looking to boost their magazine capacity with a simple tool free upgrade.
