Besides being an avid Airgun collector I also dabble in pocket knives and watches, all of which fall into this conversation. When it comes to quality in China, you choose whether or not you want something to be made cheaply or well. Your costs change accordingly this becomes very evident with pocket knives where you can get a Chinese pocket Knife for $10 which is a piece of junk or one for $500 which is made exquisitely.
Keep in mind that that same $500 Chinese knife would cost anywhere between 800 and $1200 if it was made in the US. Many of us in the US think that because it’s made in China it’s cheap and it’s junk. This is not the case. If you want something high-quality made in China they are very capable of doing so but it is reflected in the manufacturing price. A good example is the iPhone, it is made in China, but admittedly a very high-quality piece of engineering. You also have the additional cost of the vendor profit.
If the Hubens were made in the United States, they would be much more expensive. Keep in mind these guns are engineered to hold and work under 5000 psi of pressure. This takes tremendous skill, high-quality materials and very exacting standards. I have both the K-1 and the GK one and find that even though there are things that I would change or improve the quality of both is extremely high and they are both very reliable if used properly.
The days of everything from China being cheap junk are long over.
