There are so many calibers in the market, including .308 Winchester, 7mm-08 Rem, 6.8 SPC, .223 Remington, 7.26x51mm NATO, and 6.8mm among others. Choose the correct chamber for your desired shooting.

You must be able to get a positive appreciation of the weapon the moment you put it to use. Most rifles with free floating parts are known to offer maximum performance because there is no stress to the barrel.

Ergonomics

The very first thing that you must consider is the weight. The most convenient rifle is a lightweight one, which you can easily carry and be able to sit on your target. As much as comfort depends on your technique, the ease of shooting does entirely depend on the ergonomics of the various parts, including the stock, barrel, trigger, lower receiver, and upper receiver.

Choose a rifle that features a fully adjustable stock, and a target pistol grip. Basically, you should take parts compatibility as well as weight reduction into account. Try as much as possible to choose a two-stage trigger type, especially for range shooting performance.

    Unfortunately, the AR-15 receives a lot of bad press, with some less than desirable people using this as their weapon of choice for some particularly gruesome means and many will argue that hunting with this type of weapon is unnecessary.

    These people may be right, however, in my opinion, they are right in the sense that luxury cars or expensive fashionable clothes are unnecessary, we may not actually need them but they make life better, easier or more enjoyable.

    I believe the same argument can be applied to using the AR-15 to hunt, though there are, of course, alternatives such as a bolt gun, a bow and arrow or even a sharpened stick if you’re feeling brave enough, the AR-15 makes hunting easy. There have been times that if I were hunting with a bolt action, I’d have perhaps snagged one rabbit, using an AR, however, I managed to get 4. A rifle definitely worth considering for hunters.

      It is all about the subjective feel of the rifle that matters in the end. If you are comfortable with your purchase and complements your hunting experience, it should be more than alright. The AR-15 is a great choice, and I have recommended this to my friends who wanted a powerful semi-auto rifle.
