Description
Ares M45X-S with EFCS Gearbox (Retractable Stock with Arm Stabilising Brace – Black – AR-085E)
The Ares M45X-S is a compact sub machine gun style AEG built on Ares’s M45 platform. It combines the familiar controls of an M4 carbine with a 9mm SMG style magazine, giving a short, quick-handling replica that is right at home in buildings, corridors and tight woodland. This retractable stock with arm stabilising brace version (AR-085E) is finished in black.
What sets the M45X-S apart is the electronics. Its reinforced gearbox is built around Ares’s integrated EFCS (electronic fire control system) module with a built-in MOSFET, so the trigger is crisp, the contacts are protected and the rifle is ready for LiPo batteries from day one. Add tool-less assembly and quick-change front sets and you have a modern, modular SMG that suits CQB specialists and anyone who wants a compact primary or backup.
Build and configuration
The M45X-S has a metal receiver and handguard, held together with steel pins and screws, with a polymer pistol grip. Ares designed the platform for tool-less assembly, so the front set can be changed and the rifle stripped down without a toolbox, which makes routine cleaning and reconfiguring between sites far easier than on many AEGs.
This version is fitted with a retractable stock that incorporates an arm stabilising brace. The stock collapses to keep the gun short for storage and transport and extends to give a steady hold when you shoulder it, while the brace profile gives it a distinctive, modern PDW look.
Flip-up iron sights give you a sight picture straight away and fold down out of the way when you fit a red dot or holographic sight to the top rail.
Performance and electronics
Inside is a reinforced gearbox designed specifically for the M45 series, driven by an Ares slim motor. The EFCS module replaces the traditional mechanical trigger contacts with electronic control and a built-in MOSFET, giving a sharp, consistent trigger response and protecting the internals from wear.
Out of the box the M45X-S fires on semi and full auto. With Ares’s optional EFCS programmer, sold separately, you can set up programmable fire modes including a three-round burst. The controls follow the AR layout, and the safety selector is ambidextrous, so left- and right-handed players are equally at home.
Getting started
Fully charge a suitable battery before first use, then fit it as described in the manual and connect it carefully. Load a magazine, wind it if it is a high-capacity type, and start with the hop-up turned off. Fire a few shots at a safe target and add hop a little at a time until the BBs fly flat without rising at the end of their flight.
Have the rifle chronographed at your site before you play, and keep a note of the hop setting that suits your favourite BB weight so you can return to it quickly.

Compatibility
The M45X-S takes dedicated Ares M45 series magazines, available in mid and low-capacity styles, so make sure any spares are made for this platform rather than standard M4 or other SMG magazines. The EFCS module is happy with LiPo batteries; choose a compact pack that fits the battery space in your configuration and check the connector before ordering.
Rail sections accept standard 20mm accessories. Front sets, gearbox parts and many internals are specific to the Ares M45 series, so check that any upgrade or spare is listed for the M45 before buying. The EFCS programmer is a separate purchase.
Care and maintenance
Take the battery out after every game and store it away from the rifle, and charge LiPo batteries only on a proper balance charger under supervision. Clean the inner barrel with a cleaning rod and a dry cloth patch every few games, as dirt and broken BB fragments are the main causes of flyers. Stick to good quality seamless BBs of a consistent weight.
Check screws, the flash hider and any mounts before each game day, and store the rifle somewhere dry. Leave the hop-up at a light setting in storage, and if the rifle has an electronic trigger unit, a fully charged battery helps it read the trigger cleanly.
Who is it for?
The M45X-S retractable stock with arm stabilising brace suits CQB and indoor players who want a short, light primary with modern electronics, and outdoor players who want a compact second gun that can be reconfigured quickly. Its AR-style controls make it an easy step for anyone already used to an M4.
Please note: A battery and charger are not named in this listing, so please check with us before ordering. Always wear suitable eye and face protection and have the replica chronographed at your site before play.
