Hello friends I'm having a dilemma on upgrading my KWA aeg. It's a great gun straight out of the box but, I want more consistency and a bit more range. The problem I have found is KWA does not seem to be aftermarket parts friendly, mainly with the hop up unit and I believe air nozzle. I am going to give you the rundown of what I want to do, and hopefully this community can help me adjust some things. My ideal upgrade parts would be a PRO WIN M4 style rotary hop up unit, Prometheus purple bucking, Firefly namazu nub and a ORGA inner barrel. Yes this is to flat hop and I like the ORGA barrel because it does not require you to shave the bucking. With KWA the hop up unit is very slim so I fear I would be stuck using it, which is fine but can I change the nub? Also will this bucking and barrel still work with the proprietary unit? Just to clear this up now, my aeg does not have a two piece hop up it's all one, KWA seemed to fix that problem unlike older guns they made. Thank you for taking the time to read my thread, I am open to all suggestions.
