MM Lightning Short Magazine Base Extender (+3)

The MM Lightning Short Magazine Base Extender (+3) bumps your Lightning magazine up to a 13-dart total capacity, giving you three more shots before a reload without adding much bulk to the base. It's a straightforward friction-fit design — no rails, no ergonomic contouring — that presses onto the bottom of the magazine and holds tight enough not to slip off during use.

Unlike the Ergo version, this Short base extender is built to work alongside the MM Lightning Magwell Flare if you're also running one, so you can stack both upgrades on the same magazine. Note: product photos showing the flare and base extender together are for illustration only — the flare is sold separately and not included in this listing. Available in Black and Orange to match the rest of the Lightning accessory lineup.
