The long eye relief, locking diopter, and fully multi-coated lenses are just a few of the reasons this riflescope will be a crowd pleasing

Tough construction and bright images are just the icing on the cake. 
The Copperhead's hard anodized, one piece, aircraft grade aluminium tube is nitrogen purged and O-ring sealed for waterproof/fogproof/weatherproof performance.
 
OPTICAL FEATURES 
Fully Multi-Coated Lenses - Increase light transmission with multiple anti-reflective coatings on all air-to-glass surfaces.
 
CONSTRUCTION 
One Inch Tube - Standard tube diameter for most American riflescopes.

One Piece Tube - Maximizes alignment for improved accuracy and optimum visual performance as well as strength and water resistance.

Aircraft Grade Aluminium - Premium grade of aluminium, valued for fatigue resistance.

Capped Turrets - Less susceptible to accidental impact damage.

Reset Turrets - Allow re-indexing of the turret housing to zero after sighting in the riflescope; generally requires use of a coin or wrench.

Waterproof - O-ring seals prevent moisture, dust, and debris from getting inside the tube, ensuring reliable performance in all environments.

Fogproof - Filled with nitrogen gas to inhibit internal fogging.

Shockproof - Lenses are locked in place, fore and aft, with machined locking rings to remain in perfect alignment and withstand recoil and impact.

Hard Anodized Finish - Hard coat anodization is durable; the low glare matte helps camouflage the shooter’s position.
