D|Boys BY-052 MK12 SPR Airsoft AEG Rifle in Blue
If you're after a reliable, field-ready airsoft rifle that sits comfortably in the designated marksman role without the hassle of a million upgrades, the D|Boys BY-052 MK12 SPR AEG in striking blue might just be your new favourite piece of kit. Built around the iconic SPR (Special Purpose Rifle) platform used by US forces in Afghanistan and Iraq, this airsoft AEG rifle blends DMR-level performance with M4/M16 compatibility, giving you the best of both worlds.
From the moment you pick it up, you’ll notice the solid feel. This airsoft rifle features a full metal body with nylon polymer for the pistol grip and solid stock. The free-float RIS up front is also full metal, giving you loads of space to mount your favourite accessories—scopes, lasers, torches, you name it. The addition of two rail covers straight out the box is a godsend; the rails can be sharp (ask anyone who’s scraped their hand mid-game), so the covers help keep things comfortable during extended use.
Under the hood, this beast packs a full metal Version 2 gearbox fitted with 7mm bearings, making it both durable and fully upgradeable. Fancy a tighter grouping? Swap in a tight bore barrel. Want to squeeze out even more efficiency or responsiveness? Drop in a pre-built V2 gearbox—it’ll fit no problem. Unlike platforms like the SR-25, this MK12 SPR shares 100% of its parts with M4s and M16s, including magazines, so you're not stuck with proprietary gear. That’s a major plus for anyone already running STANAG-compatible rifles in their loadout.
It comes shooting at around 400 FPS out of the box (manufacturer quoted, pending chrono), which puts it squarely in DMR territory for most UK fields. So yeah, this isn’t something you want to bring to a CQB arena, but for long-range skirmishes? Oh, it sings. The hop-up is fully adjustable and easy to dial in for heavier BBs, like 0.28g or 0.30g, which is where this airsoft AEG rifle really starts to shine in terms of accuracy and consistency.
Included are some nice extras: a folding bipod and vertical foregrip—so you’re halfway to the full DMR look without spending more on extras. The backup iron sights are foldable too, meaning you can start playing right away without needing to source an optic. Still, for optimal use, pairing it with a red dot sight or an ACOG-style non-magnifying optic is a solid shout. Trust me—unless you're shooting on a football pitch, you won’t need a magnified scope.
The fixed solid stock is built to house larger batteries, giving you options for longer skirmishes without recharging. It’s a big bonus for DMR players who spend more time on overwatch and less time respawning. The magazine included is a stubby 200-round high-cap VN-style cap, but this rifle accepts pretty much any STANAG mag you throw at it—mid-caps, high-caps, you name it.
In terms of looks, the blue finish sets this one apart. It’s not your typical all-black operator look, but it still feels tactical and functional. If you’re the kind of player who wants something a bit different without looking flashy or gimmicky, this hits that sweet spot.
The D|Boys BY-052 MK12 SPR is a proper skirmish-grade airsoft AEG rifle—field-ready from day one and built for players who want to stretch their range without diving down a rabbit hole of upgrades. It’s dependable, accurate, and oozes that light-sniper aesthetic without needing a custom build.
