From the one video of some chinese guy that dissasembled the replica, looks like it has brass cyilder type 2 which for this length of barrel is pretty good. The gears appeared to be in standard, 3x 8mm ball bearings, blue hop-up bucking in standard(I have G&G TR16 MBR 556WH an it have also blue bucking, i recommend changing it to maple leaf bucking xD), the cylinder head is aluminium and tapped plate looks propertiary, short plastic nozzle(Don't know if it has some o-ring), piston looks like to have full metal teeths, piston head is ventilated, plastic and have an o-ring(Don't know if it's on a bearing), looks like it has quick change spring system, where you twist the spring guide and easly remove it, the spring guide is aluminium and on bearing. The most painful is the dissasembly of fire selector switch, it has a big amount of additional gears and springs. The motor is Ifrit 25k long neodymium magnet from their previous G2 gearbox. For the etu, i recommended changing the stock etu for ETU++ from perun if its compatible, the previous etu in battery compartment has known to fry the electronics and probably they use their faulty etu again. th-cam.com/video/471_PZ9pcR8/w-d-xo.html Here is the link for the video of full dissasembly.
Latest evolution of G&G looks really good!
Finally, a review covering everything while not shilling out for G&G.
Can you possibly do a 10 best ars 300$ and under please?
Just FYI the music doesn't help when you are trying to talk over it, but aside from that nice review
so it is not possible to change the hop-up system in this rifle?
Unfortunately no due to the fact there are also sensors to help indicate bb’s sent out of the hop up chamber if I recall.
What type of Cylinder is in it?
