Vortex or Millett

PST is Philippines, I believe the other Vipers are China... I'm not expert, but Philippines glass is said to be better than China.

Mmmmm...not. The Viper is made alongside Monarch's in PI (with Japanese glassTMK)

The Razor line is Japan

The Crossfire line is China.

so the glass in the Viper, Viper HS, Viper HS-T and Viper PST are all the same? and they are all made in Philippines?

What are the key differences?

HS, eye relief and mag range
HS-T, turret
PST, FFP and fancy reticle.

Perhaps there's more, but not something you'll tell by looking through it.

Catalogue stuff.
