I have not looked through the “Forge” binocular. China is very capable as a nation to manufacture weapons, optics, submarines etc.
There are two issues or me; both personal - albeit admittedly a limited experience.
1) For a few years I worked in a LEO capacity trying to stave off the unrelenting theft of intellectual property by China from USA companies. As a result, as much as possible I will pay more for products not produced in China.
2) Hunting versus PRS. Huge difference in requirements for success.
PRS: Daytime observation targets, splash, trace and hits on steel. No doubt the Forge and others are just fine. Under those conditions you will not see a significant difference between the expensive Alpha glass and those which are lesser in optical quality, coatings etc like mid or lower priced optics.
Hunting: Daytime animals bedded in deep shaded timbered or Sage country. Look for an ear flicker, a horn move versus a wind driven branch, color differential - log, rock or Elk hide? Most importantly the ability to observe as clearly as possible the first and last 15 minutes of legal light is why ALPHA’s are used. Line them up in the aforementioned conditions and the mediocre glass regardless of Country of origin are no comparison to $3K Glass.
If I was not such a fanatical hunter I wouldn’t own 10K in glass. It is simply a choice but or any mid range optic is not going to give me the results I desire for hunting.
PRS only, go for it. Especially if you want to support the Country of origin.
Image 3; You would be able see these 1000 plus yard hits through any decent sub $500 glass.
Image 1; (enlarged so you can see more clearly) I watched this nice desert Muley @ 600 yards while hunters walked right by him, glassing with their rifle scopes (!!???) or ______ binoculars.
Image 2: non enlarged same as #2 but with my Austrian manufactured 15x56 binocular I could clearly see this dude.
