El Bridos 5.95 talk about their build project, combining AEG, HPA, and GBBR systems. Starting with a Double Eagle Ghetto Blaster (GBBR), it's converted to HPA using an Airtac kit for AEG magazine compatibility. External modifications include an Airtac "ponté" for HPA line routing and a Tier One Precision angled foregrip. Internal upgrades feature a Silverback hop-up, BFTAc nub, NPass nozzle, and a TTI inner barrel. The setup offers GBBR kick with AEG magazine convenience and HPA consistency, achieving excellent range and accuracy.
