Description
Amoeba by Ares Mutant AMM13 EFCS AEG (Black – AM-M-004-BK)
The Mutant AMM13 is the longer, rifle-length model in Ares’ Amoeba Mutant series, and this listing is the black version (AM-M-004-BK); a tan version is also available. The Mutant range combines sculpted, lightweight polymer receivers with Ares’ electronically controlled gearbox and a modular front end, giving a modern, distinctive rifle that is light to carry and easy to adapt.
Ares is well known for its electronic gearbox technology, and Amoeba is its range of lighter, more accessible rifles. The AMM13 suits players who want the Mutant’s features in a longer rifle better suited to outdoor sites, while keeping the low weight that makes the range popular.
Compatibility
Accepts Ares and Amoeba M4 AEG magazines and standard M4 AEG magazines. Use a 7.4V to 11.1V LiPo battery; check the battery space and connector before buying. Front-end assemblies and the EFCS programmer are Ares/Amoeba parts, so contact us for advice on reconfiguring your AMM13.
Care and maintenance
Always disconnect and remove the battery after play, and store LiPo batteries at storage charge in a fire-safe bag. Use seamless, good quality BBs, and clean the inner barrel with a rod and dry patch if accuracy falls off. Keep the gun and its electronics dry, and allow it to dry fully if it gets wet in the field.
Who is it for?
The Mutant AMM13 suits outdoor and woodland players who want a light, modern rifle with electronic trigger control, and anyone looking for a distinctive alternative to the standard M4 that still takes common magazines.
Please note: Battery and charger are not included unless stated. Use good quality seamless 6mm BBs. Always wear suitable eye and face protection, and check your site’s power limits before play.
