Today we’re going to take a look at how to choose the best AR-15 scope for hunting. We will also classify some of the best AR-15 scopes for deer hunting available in the market. So here we go.

What To Look For In A Scope For Deer Hunting
Deer hunting is probably the most common hunting session in open seasons, at least in America. The deer we are talking about here refers to smaller species like the whitetail and mule deer. Deer hunting is done at quite close ranges, usually within 200 meters. Many deer hunters say they haven’t bagged one beyond 100 yards. All those factors have to come into play when choosing a scope.
Some very prominent factors to look for when choosing and AR scope for hunting are:
Resolution, also termed sharpness, is the ability of a lens to differentiate between two close images and show them as separate entities. In layman terms, higher resolution means sharper images. That means you’ll get to see the target as perfectly as with your naked eye. A clear image of the target lets you make a perfect target picture for a precise shot.
Objective Lens Size
The size of the objective lens determines the amount of light that enters the scope. Lenses with a large objective size allow more light to pass through, which in turn produces a brighter image. While you’re out with your AR-15 to hunt a game, lens size really comes into play at dawn and dusk, which are often the best times to find deer in the open. At these times between light and dark, you’ll want a scope that can pull in as much light as possible.
Magnification is the amount of enlargement your scope can provide for an image. For example, a scope with 3.5-9x magnifications means you can view an object 3.5 to 9 times closer than you can with your naked eye. Magnification is often a topic for debate among deer hunters. We’ll discuss it later as to how magnification matters when you’re shooting a deer only 100 yards away.
It’s not very less likely that you’re going to find a whitetail lingering around in your backyard - or at least you’re not going to shoot it there. You have to carry your equipment and rifle into the woods across uneven terrain and facing tough weather conditions.
A good scope must also hold zero in all conditions. You should make sure that the scope of your AR-15 is quite sturdy as well as being waterproof and fog proof. A sturdy scope is quite effective and no doubt goes a long way.
Bigger is Better, Right?
You don’t have to shed your heart out of your pocket to buy a good scope for deer hunting. Bigger is not always better. There are certain factors which will let you decide about how to choose a good scope.
Some people might suggest that high magnification scopes are always good. But that’s not really the case with deer hunting. You’re probably never going to shoot a deer far more than 200 yards, and scopes with more than 12x magnification are useless in that respect.
Moreover, you are probably not going to find deer on wide stretches of land. Deer hunting generally happens in wooded areas or other “broken up” terrain. You’re not often shooting across the wide savannah. A high magnification scope would show you nothing more than zoomed tree trunks. You should probably stick with 3-9x scopes for hunting deer, as they will help you acquire a target picture instantly, especially if you are stalking your target in the bush.
Another important aspect to note here is the objective lens size. As we know that a larger size means a larger image. But there are a couple of contradictions in using it while deer hunting. Much deer hunting is done in daylight. While you might be out at dusk or dawn, you might not need a huge objective lens - “just enough” should do. On top of that, larger objective lenses may reflect sunlight and the flash might scare away your target. Plus a larger objective lens is heavier and will add to the weight of your gear.
Apart from all these mentioned features, some other basic things to look for in a scope are eye relief, reticles and minutes of angles for correcting your shooting.

Hunting deer is not a very long range activity (unless you are very fond of doing so). A deer hunting scope should have a modest magnification range, probably up to 12x.
The objective lens doesn’t make a huge difference but make sure the lenses of the scope are multicoated. Mounting these scopes on your AR-15 is not a problem and it adds to your accuracy for sure. Always make sure you buy a weatherproof and durable scope for deer hunting so it doesn’t succumb to the harsh conditions.
