Hello y'all! Could someone out there explain to me what is meant by the sight radius of a rifle? I have been reading how the sight radius on a longer barreled rifle is better than that of a carbine.

Everyone out there have a joyous and safe holidays! Enjoy all the advantages that this country affords to all of us!

Sight radius is the distance between the front and rear sights.

Correct, and the longer the sight radius is, the easier it is to allign the sights more accurately. That is why the longer sight radius of the standard 20" AR15 is easier to be accurate with than the short sight radius on the carbine. If you want the long sight radius but like the short barrel, get a Bushmaster Dissipator. It uses a 16" carbine length barrel, but uses the longer sight radius.

The sight radius issue is the reason that it is typically much easier be accurate with a rifle than it is with a handgun.

Well, that's not entirely true. With a handgun, most peole shooting offhand are more accurate out to 25 yards with a short barrel (hence a short sight radius). This is because the longer sight radius in a handgun makes it much more difficult to hold a steady sight picture. It's almost purely a comfort factor, rather than a technical one, but after training hundreds of LEO and civilians, it's just a quantitaive observation.

The reason people shoot better with a rifle is because it has a stock and is more stable. Once its stable a longer sight radius will help even more.
