AirTac VFC M249 GBB HPA Adapter & AEG Box Conversion V2
Unleash unrelenting suppressive fire without losing the spine-tingling recoil of a gas blowback platform with the AirTac UK VFC M249 GBB HPA Adapter & AEG Box Conversion Kit (V2). Precision-engineered in the UK by AirTac UK, this game-changing conversion allows you to convert your VFC M249 GBB heavy machine gun into a high-capacity, HPA-powered squad support weapon that feeds directly from standard AEG-spec M249 box magazines.
The upgraded V2 Edition features an enhanced VFC cassette locking tab mechanism to eliminate wear over time, providing a rock-solid, wobble-free lockup inside the magwell. Made using ultra-durable, high-strength printed polymers alongside premium branded HPA push fittings, this kit replaces gas cool-down and low-capacity gas mags with constant line pressure. Give yourself thousands of rounds of continuous gas-blowback heavy suppression with the AirTac VFC M249 GBB HPA Adapter & AEG Box Conversion V2.
Why You Need the AirTac GBB HPA Adapter & AEG Box Conversion Kit:
- V2 Reinforced Locking Tab: Built utilizing an original VFC cassette locking tab design for maximum magwell retention and long-term durability.
- AEG Box Magazine Conversion: Seamlessly routes BBs from standard A&K or classic AEG M4/M249 auto-winding box magazines directly into the VFC GBB feed ramp.
- Zero Structural Modifications: A 100% "from scratch" conversion kit that installs cleanly without requiring permanent frame cuts or drilling.
- Industrial-Grade Branded Fittings: Equipped with high-spec push-fit macro-line connectors and a standard US Foster quick-disconnect fitting for leak-free, high-pressure air delivery.
- Constant FPS & Heavy Recoil: Regulated HPA power eliminates gas-freeze slowdowns, ensuring consistent velocity and high-RPM recoil impulse during extended suppressive bursts.
- AirTac Lifetime Warranty: Built to withstand demanding LMG skirmish use and backed by AirTac’s lifetime manufacturer guarantee.

BZ Tech Team Advice:
- Empty Mag Switch Activation: Inside the receiver of your VFC M249 GBB, make sure to actuate the internal "empty magazine" sensor switch so the gun fires continuously when feeding from an external box mag.
- Auto-Winding Box Mag Control: Standard sound-control box magazines can be inconsistent with GBB fire notes. For optimal BB feeding, we recommend using an intelligent auto-winding box magazine or wiring a microswitch directly to your trigger assembly.
- Installing the Bowden Spring: Connect the BB feed Bowden spring from your AEG box mag to the adapter's feed clips, then gently tighten the two included grub screws to bite down on the spring for a secure, slip-free BB guide.
