As a machinist, I cringe at what China Freight sells! But, I needed a paint gun for cheap and after opening 6 kits with a large and small gun in them, I took all the best parts from all 6 kits and got a decent spray gun kit

I'm surprised no one came over to me and asked me what the hay I was doing because it took me a good 30 minutes to tear everything apart and assemble one good kit and then put all the others back together again lol. Man, most of that stuff is plain junk and there is no way I'd ever buy a tap kit from them....
