A&K M249 MK2 AEG with Sound Control Drum Magazine (Hard Stock) AK-249-MK2

The A&K M249 MK2 AEG is a full-size support weapon replica built for players who want genuine LMG firepower on a UK skirmish field. It pairs a full metal, 8mm-bearing gearbox with a huge 2500-round sound-activated drum magazine, so the M249 role runs on ammunition rather than reload drills. A metal receiver, polymer furniture, folding steel bipod, and adjustable hop-up round out a platform built to hold a firing line rather than push through doorways. Where a standard AEG rifle asks its user to manage magazine changes mid-firefight, the M249 MK2 is built around the opposite idea: carry enough ammunition that reloading stops being a concern, and let the rest of the squad manoeuvre around your suppressive fire.

Key Features

• 2500-round sound-activated drum magazine – feeds automatically as you fire, giving the support gunner near-limitless capacity without manual winding mid-game.
• Full metal gearbox, 8mm bearings – reinforced internals built to cope with the drum mag’s demands over a full day’s skirmishing.
• Quick-change spring system – swap spring in minutes to match different UK site FPS limits without a full teardown.
• Metal receiver + polymer furniture – authentic M249 weight and durability without carrying excess bulk across a woodland field.
• Folding steel bipod – drops into a stable prone or supported firing position, exactly how the real support role is played.
• Adjustable hop-up and sights – dial in trajectory for your BB weight and aim without relying on an optic.
• LiPo/Li-Ion battery compatible – runs modern high-discharge batteries for a consistent rate of fire through the drum mag.
• M4/M16 AEG magazine compatible – accepts standard AEG mid-caps and hi-caps as a lightweight backup (excludes G&P and other box-style mags).

Real-World Use Cases

Woodland skirmish support gunner – hold a firing line and suppress lanes with the drum mag’s huge capacity while your squad manoeuvres, exactly the M249 SAW support-gunner role it’s built to replicate.

Milsim support weapon – runs a full day’s game without hunting for spare mags, backed by a full metal gearbox built for sustained trigger time. Deploy it at the centre of a fire team so riflemen can push and flank while the M249 keeps heads down.

Static/defensive positions – the folding bipod turns this into a genuine base-of-fire weapon for holding a point, best suited to outdoor UK sites running 0.25 g–0.28 g BBs at their standard skirmish site limit. Set up on a rise or treeline and the bipod does the work a standard AEG stock can’t.

Compatibility & Upgrades

The drum magazine ships sound-activated and pre-loaded for extended fire, and the M249 MK2 also accepts standard M4/M16 AEG magazines as a lightweight backup — this excludes G&P and other box-style mags, so check compatibility before buying spares. It runs on both LiPo and Li-Ion batteries, and the adjustable hop-up is tuned for a range of 0.25 g–0.30 g BBs to keep trajectory flat at engagement range. The full metal gearbox and 8mm bearings give a solid base for players who want to tune shot cycle or fit a higher-capacity spring further down the line, though most owners will find the stock setup handles a full skirmish day without issue.

UK Legal & Site Notes

At 390 FPS (1.41 J) with 0.20 g BBs, always check your site’s FPS/joule limit before your first game, as many indoor CQB venues cap support weapons below this figure; this A&K M249 MK2 AEG is best matched to outdoor sites that permit full-power support guns.
