Description
Ares x Sharps Bros. Hellbreaker Pro. M4 15″ (Tan – M4-SB15-DE)
The Ares x Sharps Bros Hellbreaker Pro M4 is an M4-style electric rifle (AEG) made by Ares in collaboration with Sharps Bros, the American firearms parts maker known for its distinctive, aggressive receiver designs. This is the 15-inch version, finished in tan, with the code M4-SB15-DE.
A 15-inch M4 has a longer handguard and more room for your support hand and accessories, giving a steady hold for aimed shots at range while still handling well in woodland. The Sharps Bros styling gives it a look that stands out from a standard M4, and it suits players who want a capable rifle with a recognised licensed design.
Design
The Hellbreaker name comes from Sharps Bros’ aggressive, angular receiver design, which gives the rifle its distinctive profile. The tan finish suits desert and arid-style loadouts and pairs well with coyote and multicam kit.
Retailer listings for the Ares x Sharps Bros Hellbreaker Pro range describe removable flip-up front and rear iron sights, an enlarged magazine release, a rubberised slip-resistant pistol grip, a slip-resistant rubber butt pad, a full-length uninterrupted top Picatinny rail, a QD sling attachment point and an adjustable stock, along with a weather-resistant finish. Please check the product photos for the exact layout of this 15-inch model.
Performance
Retailer listings for the range describe a full metal gearbox with reinforced internals, an adjustable hop-up and safe, semi and full-auto fire modes. Set the hop-up for your chosen BB weight before your first game, and have the rifle chronographed at your site.
The longer front end gives you more rail space and helps steady the rifle when shooting from cover, making the 15-inch version a good all-round choice for outdoor sites.
Other versions
We list the Hellbreaker Pro in several lengths and finishes, including 7-inch, 10-inch and 15-inch versions in black and tan, so you can choose the front-end length that suits the way you play. A black 15-inch version is also available.

Battery type, connector and battery space are not confirmed for this model, so please check the manual or ask us before buying a battery, and check the model code before ordering internal parts.
Care and maintenance
Take the battery out after every game and store it separately at a sensible storage charge, rather than leaving it connected inside the replica. Charge LiPo batteries with a proper balance charger, keep them in a LiPo-safe bag and never leave them charging unattended; NiMH packs should be charged with a smart charger that stops when the pack is full.
Run a cleaning rod with a lightly dampened patch through the inner barrel from time to time to clear dirt and residue, which keeps the hop-up consistent. Use good-quality seamless BBs, never reuse BBs that have been on the ground, and wipe the outside over after damp or muddy games. Leave gearbox work, shimming and spring changes to a competent technician.
Who is it for?
The Hellbreaker Pro M4 15-inch is for players who want a distinctive, licensed M4 with a quality gearbox. The 15-inch length suits outdoor and woodland sites, and the tan finish suits desert-themed loadouts.
Please note: A battery, charger and BBs are not listed as included. Always wear suitable eye protection, and full-face protection where your site requires it, when using or testing any airsoft replica.
