Description
EMG – Jack – 14″ – Black
The EMG Jack is a licensed M4-style electric rifle carrying the distinctive styling of Sharps Bros., the American maker known for its bold Jack receiver design. Built by Ares for EMG, it combines that striking look with an Ares electronic gearbox. This version is listed as the 14 inch model, finished in black.
EMG specialises in officially licensed replicas, so the Jack carries Sharps Bros. markings and the angular receiver profile that makes it stand out from a standard M4. It is a rifle for players who want something with real character, backed by the reliability and programmability of Ares electronics.
Build and ergonomics
Retailer listings for the Jack range describe an aluminium upper and lower receiver and a CNC-machined aluminium handguard, finished in a weather-resistant anodised coating. Details include a bevelled magwell, an oversized trigger guard, an enlarged magazine release, a functional bolt stop, a rubberised pistol grip, a flat match-style trigger and a QD sling point.
A full-length top rail takes your optic, and flip-up front and rear sights are fitted. The adjustable stock has a slip-resistant rubber butt pad for a secure shoulder mount.
Ares EFCS gearbox
Inside is an Ares EFCS Version 2 gearbox with 8mm bushings and bearings, fully reinforced and LiPo ready, with a quick spring change system. The electronics provide safe, semi, 3-round burst and full auto, and can be programmed with the separately sold EFCS programming unit.
The hop-up is adjustable through the ejection port. Jack rifles are listed with a 300-round mid-cap magazine and a 14mm positive (clockwise) muzzle thread; check the exact configuration of this version on the product images.
Getting started
Charge your battery on a proper charger and fit it following the manual. Load a magazine and test-fire at a safe backstop, starting with the hop-up off and bringing it up gradually until shots fly flat. A few minutes of zeroing at the range makes a big difference to your confidence on the field.
Practise magazine changes and battery swaps at home, and get the rifle chronographed at the site before your first game.

Compatibility
Jack rifles accept M4/M16-series AEG magazines from Matrix, G&P, Tokyo Marui and other makers, though fit can vary, so test spares before game day. The muzzle thread on Jack rifles is listed as 14mm positive (clockwise), so check muzzle devices are the right direction. Ares EFCS parts are specific to Ares rifles, so make sure upgrade or replacement parts are listed as compatible.
Care and maintenance
Unplug and remove the battery after use, store LiPos in a fire-safe bag, and charge them on a balance charger you are watching. Keep the inner barrel clean with a rod and patch, because a dirty barrel or hop-up rubber is the most common cause of poor grouping.
Use good quality, polished BBs and avoid reusing BBs picked up from the floor. Keep the rifle dry, check all external screws now and then, and leave internal servicing to someone who knows AEGs well.
Who is it for?
The Jack suits players who want an officially licensed rifle with a distinctive look, Ares electronics fans and anyone looking for a high-quality M4-style rifle that stands out.
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 when using or testing any airsoft replica.
