It really comes down to something as simple as .. if people aren't buying it, they won't be making them. G&P's been churning out AR variants for years, non-stop, new ones every few months, and yet they keep on coming, so clearly there's a demand somewhere, also the sport of airsoft is growing all around the world, so these may well be many's first AR.
As much as there are tons of AR AEGs made by various companies, there's still yet one made that is "perfect", with TM next-gen (+BTC) / Magpul ERG (?) being the closest imo as they are the only two with both recoil and a bolt stop, but some aspect of realistic handling is still missing, something that the mythical Real Sword M4's been suggested to be attempting, so there's still plenty of room for the AR AEG to expand into. Helped by releases like this, when it becomes a norm that all AR variants are expected to have recoil, then it's only natural for others to start ensuring EBB to be a standard requirement for AEGs regardless of gun model, which can only be a good thing.
