GHK V2 AKs were decent once you fixed all the issues in them with aftermarket, but late V2s started to have absolutely awful quality control issues. Completely bent guns, things just breaking, awful.
They did a big song and dance for their V3 update but while it fixed a bunch of design issues...
Being a first batch VFC AK74M is actually a negative as well. They had bolt bounce issues that were corrected in subsequent batches.
It has an aluminium nozzle, so it's someone who doesn't know anything about teching GBBRs.
The parts are all 5ku and Cyma, so they're cheap and don't add up to...
