I made up a metal barrel and a flash hider from parts at Bunnings :D. I added a MOE front grip and better bipod and I also cut off the ridiculous front sight that comes moulded into the body as it doesn’t line up with the rear sight and used the M4’s front sight (turned around). I’ve got some flip up sights on order for the M4 but the Aimpoint works fine anyway.
Only internal upgrade at the moment is a slightly bigger spring, better o-ring and 11.1v battery but I’m planning on an alloy inner barrel and hop up in the near future. The main thing I want to do though is to add in a big chunk of metal inside the body to give it some weight, it’s way too light.
Oh, I also cut away a lot of the plastic from under the heat shield so you can see the barrel, looks a bit more realistic IMO.
