Rated 5 out of 5 by from Great simple scope Bought this scope to hunt whitetails on the east coast and elk in Montana. I have been super pleased with it over the last 7 years. I have harvested deer at 70 yds and elk as far out as 360 yds. You just can't beat a Vortex for quality and customer satisfaction.

Rated 5 out of 5 by from Better eye relief than other brands Was comparing this to a luepold at the local gun shop and came home with the Vortex. Not let down. Talked to customer service about a few things, gentleman was very friendly and helpful. Found out the issue was operator error. Plus, nobody beats the warranty.

Rated 5 out of 5 by from High quality scope for the money I mounted this Viper 4-12 on my Savage 112 7mm REM MAG and enjoy the clear view and crisp reticle on this flat shooter. Hitting 8 inch steel at 600 yards. This goes with me on my elk and mule deer hunts coming up in the fall.

Rated 5 out of 5 by from Great scope! I hunt Colombian Blacktail in the northwest of California near the Oregon border. While hunting the "grey ghost" here you can find yourself with a shot anywhere from 50 yards to 500 yards or more. This scope can handle any distance you can that you can find them. It has a long eye relief. I have a long rifle for my size and this scope works for me awesome.

Rated 5 out of 5 by from You pay for what you get What can I say? Best riflescope I have ever bought for one of my hunting rifles. Quick simple sighting in at the range and deadly durable with outstanding clarity in every kind of weather out in the woods. I will never put another brand of scoop on one of my hunting rifles again. Simply the best.

How does the glass and internal parts handle the cold weather? (-30F). Also if the scope is discontinued and it breaks beyond repair what will Vortex do for support?

Asked by: titus88
The scope will work in cold weather, some of the adjustments might be a bit stiff as the grease gets cold (magnification ring for example). If something were to happen to your scope, we would do our best to fix it and if it needs to be replaced we would work with you to get a scope of equal or better quality.

Is this scope strong enough for the recoil of a 338 win mag?
Asked by: The man
That optic will withstand the recoil without issue as long as it is mounted properly. 15-18 in lbs on the screws on the rings using no loctite.

What kind of recoil can this scope handle?
Asked by: cdpurcell
That optic can handle most recoil without issue, it has been tested on magnum calibers up to 50 BMG. You'll need to make sure it's mounted properly to see optimum performance. 15-18 in lbs on the screws on the rings using no Loctite.

Is there a sun shade that will fit this scope?
Asked by: Moose
We do not currently make a sunshade that fits that optic, but I would recommend getting a universal sunshade from MK Machining. If you would like to have one made the thread pitch is M43 x .75.
