The Vipers PST's are made in the Philippines. The Hawk in China, no idea on the Falcon.
I looked at a Hawk initially and settled on a Viper PST, because of favorable reviews. We shall see how it compares to the reviews and opinions in real life (when it warms up a bit......)
The Hawk looks to me like more of an air rifle scope and I wonder how it would stand up to any recoil (air rifles recoil backward to conventional firearms, I believe). My total air gun experience is a Crossman CO2 pellet pistol....
I've always been a Leupy person and never had an issue but then I've never had a lower priced Leupy, in fact, this PST I just bought is the lowest cost scope I own.
I will say the the Viper, in appearance, looks to be a very made instrument. Fit finish and external execution is first rate as is the packaging.
If the Viper pans out as acceptable, I'll probably step up to the Razor next time. Strange name.
I have no issue with scope cost but wanted to try a Viper after reading all the favorable reviews and opinions on this site and others.
Time will tell....
