We’re going to be looking at this basic rifle, used in it’s most common role as a target range plinker from 0-300 yards, serving a secondary role as a self-defense weapon.
The very first thing you must know, without exception, is whether your rifle is chambered in .223 Remington or 5.56 NATO, or one of several hybrids chambers.
Despite the claims of keyboard commandos to the contrary, these chambers are not identical, and the 5.56 NATO round generates much higher chamber pressures. This can be dangerous, so do not fire 5.56 NATO rounds in a rifle chambered for .223 Remington. Read your owner’s manual, and if you do not have one, get one from the manufacturer. Fire only what they have designed the rifle to fire.
Now, on to the “must haves.”
The first and most obvious addition we need to make to the rifle above is the addition of a rear sight or optic. There are three basic choices to make.
- non-magnifying optics
- magnifying scopes
- iron sights
While being in the middle of building an AR-15 I am frequently researching various things from gas systems to optics. This Article from bearingarms.com sheds some like on a few basic things to consider. Your mileage may vary but give it a go. For the full article find the link at the top of this post.
