Frequently Asked Questions

What is the best chambering for an AR-15 used for home defense?

For home defense with an AR-15, it's recommended to use a rifle chambered in 5.56 NATO. This chambering allows you to safely fire both 5.56 NATO and .223 Remington ammunition, offering greater versatility and avoiding potential dangerous pressure issues.

Which bullet weights are most effective for AR-15 home defense?

What are the advantages of frangible ammunition for home defense?

Frangible ammunition is beneficial for home defense because it's designed to disintegrate into powder upon impact with hard surfaces. This significantly reduces the risk of over-penetration through walls, enhancing safety for those beyond the intended target.

Are Full Metal Jacket (FMJ) bullets suitable for AR-15 home defense?

Yes, standard 55-grain Full Metal Jacket (FMJ) bullets can be effective for AR-15 home defense. They are known to tumble and break apart upon hitting a target, which can limit over-penetration compared to some other bullet types.
