D|Boys BY-055 - M16A4 RIS Airsoft AEG Rifle in Black

The D|Boys BY-055 M16A4 RIS Airsoft AEG Rifle is a full-length, no-nonsense replica of the iconic M16A4 platform—built tough for serious players who want range, realism, and rock-solid reliability. With a full metal body and rail system, this rifle feels like a proper service rifle from the get-go. Whether you're into milsim, DMR conversions, or just prefer your airsoft rifles with some heft and reach, this is a solid contender straight out the box.

At just under a metre long (999mm) and weighing in at a chunky 3.9kg, the BY-055 isn’t pretending to be anything it’s not. This is a full-length airsoft rifle with a serious battlefield presence. The metal construction covers everything from the receiver to the RIS rail system, while the nylon stock and pistol grip help balance weight without compromising on toughness. The fixed stock has loads of room to house a large battery, giving you extended runtime for longer ops or weekend skirmishes.

Internally, you’re looking at a newer V2 gearbox setup with 7mm bearings and a long-type SHS hi-torque motor. It’s shooting around 350 FPS out of the box, which makes it ready for most standard UK skirmish sites. And for the upgrade-hungry among us, you’ll be happy to hear that it’s 100% compatible with standard M4/M16 AEG parts, mags, and gearbox components. Drop-in gearboxes, tight bore barrels, upgraded hop-up units—this thing’s a customiser’s dream.

Speaking of hop-up, the adjustable unit makes it easy to dial in accuracy with heavier BBs like 0.25g or 0.28g, giving you consistent shot placement out past 40 metres. And yes, it’s got the kind of reach and accuracy you’d expect from a DMR base—no surprise there, given its SPR lineage. This makes it a perfect platform for converting into a full-blown designated marksman rifle if that’s your jam.

The front-end RIS system gives you plenty of space for torches, grips, lasers, and whatever else you fancy bolting on. D|Boys even include two rail covers to help protect your hands from the sometimes abrasive edges—small detail, big win. The included metal 300-round hi-cap magazine feeds smoothly and is compatible with most TM-style STANAG mags, meaning you can easily mix and match with your existing loadout.

With semi, full-auto, and safe fire modes, the BY-055 can play whatever role you need it to. It's versatile enough for woodland fire support, yet precise enough to sit back and pick off targets from a distance. It doesn’t come with a battery or charger, so be sure to grab a mini-type 8.4v or 9.6v battery to get it up and running.

In all, the D|Boys BY-055 is a robust, upgrade-friendly, and downright dependable airsoft AEG rifle that captures the spirit of the M16A4. It’s field-ready right out the box and offers a superb platform for both new players and experienced techs looking for a DMR-worthy base rifle.
