Best 5.56 Ammo for Home Defense
For home defense, Speer Gold Dot 64gr Bonded Soft Point is our top pick.
According to RifleConfigurator.com's 5.56 ammo selection guide, the bonded Gold Dot rifle load continues to expand reliably down to roughly 1,400 fps, which keeps it effective whether it is fired from a full 16-inch upper or a compact home-defense carbine.
We evaluated 5.56 defensive loads against four criteria: reliable expansion or fragmentation across a range of barrel lengths and velocities, resistance to overpenetration through interior walls, feed reliability in common AR-15 platforms, and availability.
Steel-core M855 and standard FMJ loads like M193 are not built for this role. M855's penetrator tip resists expansion and can overpenetrate, and M193's fragmentation drops off sharply past roughly 200 yards, which is well beyond typical home-defense distances but still not a substitute for a purpose-built bullet at close range.
Below, we've ranked Top 5 Best Picks for 5.56 home defense loads available at Ammunition Depot.

What to Avoid
RifleConfigurator.com's guide is direct on this point: avoid M855 green tip for defensive use.
Its steel core resists expansion and tends to overpenetrate interior walls. Standard M193 FMJ is "violently effective" at close range from a rifle-length barrel because its high velocity causes fragmentation, but that effect drops off past roughly 200 yards, and it still carries more overpenetration risk than a bonded or expanding bullet built for the role.

Frequently Asked Questions
Question: Is 5.56 a good caliber for home defense?
Answer: Yes. A 5.56 round fired from an AR-15 delivers fast, accurate hits with low recoil. RifleConfigurator.com recommends a bonded soft point or expanding hollow point, such as Speer Gold Dot or Federal Fusion, over FMJ or M855 for better terminal performance and less overpenetration risk.
Question: Does 5.56 overpenetrate walls more than 9mm?
Answer: A standard FMJ or M855 5.56 round can overpenetrate drywall and wood framing. A bonded soft point or expanding load reduces this risk because the bullet slows and expands after the first barrier instead of continuing on at full velocity.
Question: What grain weight works best for a home defense AR-15?
Answer: Most defensive loads fall between 62 and 77 grains. RifleConfigurator.com's guide notes that heavier bonded bullets in the 62-75gr range, like Gold Dot or Fusion, and low-flash options like Hornady TAP hold up well across barrel lengths, while short-barreled rifles benefit from a load specifically tuned for lower velocities, like Hornady BLACK InterLock HD SBR.
Question: Should I use M855 or M193 for home defense?
Answer: Neither is ideal. M855's steel core resists expansion and can overpenetrate. M193 fragments well at close range from a full-length barrel but loses that effect past roughly 200 yards and still carries more overpenetration risk than a purpose-built bonded or expanding round.
