I really know nothing about this … creation.
It’s a HiPoint 995 9mm carbine modified for a folding stock. I’m not sure if the barrel is actually short or if that’s just a fake silencer hiding a long barrel.
Unfortunately, the HiPoint carbines have some real drawbacks. Most reviews indicate that they are durable and reliable, even if they’re a bit heavy. For me, I cannot justify purchasing one because they use single-stack magazines. I don’t want to defend myself with only 10 rounds, and 9mm is too expensive for recreational shooting.
