MM Lightning "Ergo" Magazine Base Extender (+5)

The MM Lightning "Ergo" Magazine Base Extender (+5) is the higher-capacity sibling of the standard Ergo base, keeping the same contoured shape that follows the Lightning's lower frame magazine well but adding 5 extra darts of capacity instead of 3. It's the pick if you want the ergonomic, blends-into-the-grip look without sacrificing as much capacity as the +3 Ergo gives you.

It mounts the same way as the rest of the Ergo line — a tight 3D printed friction fit that holds onto the magazine without slipping during use. Note: as with the +3 Ergo, this shape is not compatible with the MM Lightning 3D printed Magwell Flare, so if you need both a flare and a high-capacity base, the Long extender is the better match. Available in Black and Orange.
