Nikon M308 vs. Vortex Viper HS – How do they compare?

Design and Structure

Finding the best riflescope would mean finding one that does not add bulk to your hunting gear. For this reason, you may need to look into the size and weight of the riflescope. The Vortex Viper HS is lighter and slightly shorter than the Nikon M308 riflescope making it an added advantage for your hunting gear.

Aside from that, the Vortex Viper HS has a better build quality than the Nikon M308. This is seen in their internal housing features where the Vortex Viper HS is filled with fog proof Argon gas and sealed with O-rings while the Nikon M308 is filled with Nitrogen gas and sealed with O-rings. The Vortex Viper HS is more advantageous because Argon molecules are large enough to remain leak proof even after your riflescope experiences an accidental fall.

When it comes to their objective lens diameters, the Vortex Viper HS features a bigger objective lens than the Nikon M308. This means that the Vortex Viper HS has superior light collecting abilities when you are hunting in low light conditions.

Optical Performance

The Vortex Viper HS and the Nikon M308 both provide you with a wide magnification range of 4-16x that allows you to comfortably view subjects while you are hunting. They both have an eye relief of 4 inches which is long enough to ensure your eye comfort when you are viewing with or without glasses.

The difference between them is seen in their field of view, where the Vortex Viper HS provides you with a wider field of view than the Nikon M308 making it easier for you to locate your target no matter how fast they could be running.
