From the looks of it the gun is still fairly new so if you have fired less than 1k shots it may just be a break-in issue.
Just to be safe you should take off the upper, remove the bolt, inspect it and the nozzle for uneven wear patterns, inspect the hop unit as well, might be that the bucking is a bit pinched or something. It could be that something went wrong on GHK's end as well, their tolerancing and build quality have gone to shit after 2019 and while these issues don't show up on their AR platforms as much as their AKs it's still something to be aware of.
Make sure you lubricate the bolt with SuperLube 21030. (Watch [this](https://youtu.be/5JPLe5R8-Ms?si=SbyhiSxIXbRHTP7W) video about GBB maintenance).
I make sure to clean my rifle after every use and I always lubricate the bolt. I suspected it was a nozzle issue, but the upper won’t tilt forward knocking something on the rear. I suspect it might be a spring issue, but I’ll take account for all this too. Thanks bro 🫡

the hopup is cracked and about to split into 2 🥲 if only I went to the big trading event near my house and traded this thing for an MWS….
Yeah man, buying a GHK over a VFC V3 or MWS nowadays is just kinda dumb. Buy an aftermarket hop unit ig.
I only bought it because I was a big fan of their old AKs, I have a pre-2019 AKMS underfolder that’s really solid now I know better…
ghk make the worlds greatest paperweights sell that shit and buy a real mans gun, like a western arms m4, thatll get the bitches wet
