Hunt With an AR-15 The Right Way

The AR-15 is one of the most popular platforms in the world and for good reason. Most AR owners like to use their firearms for range and target shooting or self defense. But there’s another use for the platform that has been gaining steam lately, hunting.

Hunting with an AR-15 or AR-10 can safely and ethically be done when using the right caliber for the size of game you are hunting. There are also some consideration to make on your rifles setup if you plan on hunting vs target shooting.

Let’s start with the right caliber to use and then move into some upgrades or alterations you can make to your rifle to help with a successful hunt. Lastly we’ll quickly cover some legal aspects, some states don’t allow you to hunt with the AR platform.

What Caliber AR-15 Is Best To Hunt With?

The most popular calibers to hunt with an an AR-15 are .223 REM for small game and coyotes, .300 BLK for feral hogs, and 6.5 Grendel for deer and deer sized animals. Also the .308 WIN is a popular hunting caliber for deer, bear, or elk sized game.

The .308WIN however is on the AR-10 platform, not the AR-15 which just means it’s a little bigger. The AR-10 is considered a larger version for larger calibers of the AR-15 but parts and availability are not at the level of the AR-15 platform.

If you plan on hunting a variety of game, the 308 is probably gonna work for most scenarios. It’s been a popular hunting round for a very long time, and although there are some new cartridges becoming popular, it’s going to be a while before the 308 is knocked off the top of the hill.

If you plan on solely hunting deer or deer sized animals, the 6.5 Grendel is one the best options to go with. I’ve still yet to hear someone who doesn’t like hunting deer with that caliber.

Hunting Considerations For an AR-15 Rifle

The first and most important consideration for a hunting style AR-15 rifle is the barrel length. Of course you need a barrel in the correct caliber, but how far away from the game do you plan on hunting from? Also camouflaging the rifle isn’t a bad idea.

Aside from barrel, handguard, and camo, picking the right optics is the only other consideration that sets an AR-15 hunting rifle apart from an other target shooting type rifle.

AR-15 Barrel Length for Hunting

In general, a longer barrel will be better for farther distance shots and shorter barrels will offer more maneuverability when hunting closely. Most hunting AR-15s will have a longer barrel rather than shorter however.

For 223/5.56 the barrel should be 16″ to make the most of that caliber when hunting varmints, yet a 308 hunting rifle should have an 18″ or 20″ barrel.

The only time hunters choose a shorter barrel is when they’re hunting hog close up and using the 300 Blackout cartridge. The shorter 10″ barrels can proved quicker follow up shots, much needed when all the hogs bolt after the first round is fired.

I look for barrels (and any AR parts really) online at OpticsPlanet, PalmettoState, and Brownells.

AR-15 Handguard for Hunting

Most any handguard is going to work for varmint, hog, or close range hunting. But if you’re going to be hunting at any sort of distance past a couple hundred yards, you’ll want to have a free floating handguard.

The handguards that are attached to the barrel can mess with the harmonics when the rifle is fired. Add on a any attachments that are on the handguard and it just gets worse. You’re shots won’t be on target.

A free floating handguard is attached to the upper receiver not the barrel so the handguard and any attachments on it will not affect your accuracy.

You can find all types of free floating handguards online at OpticsPlanet, PalmettoState, and Brownells.

AR-15 Camo for Hunting

Having an all black rifle is usually going to be just fine for whatever type of hunting you plan on doing. However, blending in a little bit better isn’t going to hurt your chances.

The rule of thumb is to pick a rifle color that is not going to stand out on your backdrop. For example, skip all the flashy red and white furniture on your hunting AR build. Going with and olive drab or FDE depending on your environment isn’t a bad idea.

AR-15 Optic for Hunting

Getting a quality optic will really go a long way for hunting. It usually tends to be worth it to spend the extra cash to get something higher quality. Buy once cry once they say.

For up close hunting like hog and some varmints you’ll probably do just fine with a red dot or even iron sights. If you can get good with iron sights you’ll never actually need to use a red dot, they are nice though.

For any thing past 100 yards, some sort of magnification can be useful. Most hunters opt for the traditional 3x-9x magnification LPVO. The only advice I want to give is to not cheap out on your optics.

You can find the best optics brands like Leupold and Vortex online at OpticsPlanet.
