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.
