[ILLusion]

I've upgraded a few of these now.

In general, it's harder to get the power up as high as other AEG's. With that said, the new hop up design is an upgraded one piece design, so it's much improved from the traditional two piece Marui design. The new hop up design now uses a dial adjustment mechanism that rotates along the axis of the bore - not unlike a G36 or P90, and in my opinion, is ten times better than all Armalite AEG's currently on the market, which have all replicated Marui's old system. If an Armalite AEG is a must, I would not hesitate to recommend the Marui SOPMOD series over any other.

Full metal body, plus metal body, and famed Marui quality - it's hard to find reviews of these breaking down over time, because they're built to high Marui standards. Unfortunately, these also did come out at the start of the GBBR movement, so the adoption of this platform has been slow. Regardless, there is decent aftermarket support for most of the components.

Laylax is the biggest supporter of aftermarket components, with Magic Box and a few smaller companies trailing behind. Overall, the system is decent, but a bit complicated to disassemble. It's definitely harder than the standard AEG Armalite design.

My biggest reservation about the system, is that most of the parts are proprietary to the gun. Almost ALL of the parts are new, and any traditional version 2 gearbox parts will not fit. Thankfully, there IS aftermarket support, but because of the low adoption rate of the system, do not expect to be able to find replacement parts from the store just down the street if you're in a rush to find something. Almost any part for this system would need to be ordered in.
