Feature AR500 AR550
Brinell Hardness 477–544 BHN 530–570 BHN
Best Use Pistols, low-velocity rifles High-velocity rifles, magnums
Durability High Superior
Price More affordable Higher upfront, longer lifespan
Common Thickness 3/8″ to 1/2″ 3/8″ for rifle, lighter but tougher

Key Differences Explained

1. Hardness and Surface Resistance

AR550 steel is harder than AR500, offering superior resistance to pitting and cratering. That extra ~50 BHN makes a noticeable difference, especially with high-velocity rounds.

2. Target Lifespan

AR550 targets maintain a smooth surface longer making them ideal for high-volume shooters.

3. Weight and Portability

Thanks to its increased strength, AR550 plates can be thinner without compromising durability. That makes them easier to move while still taking heavy hits.

4. Rifle-Ready Performance

AR550 is the better choice for .223, 5.56, .308, and magnum rifle rounds. AR500 still performs well but should be shot at longer distances to avoid wear.


FAQs: AR500 vs AR550

Can I shoot 5.56 at AR500 steel?
Yes, but from a minimum safe distance of 100 yards and with the target angled correctly.

Is AR550 overkill for handguns?
AR500 is sufficient for handguns, but if you want targets that last longer under mixed-caliber use, AR550 is a smart investment.

Is 3/8″ AR550 as good as 1/2″ AR500?
In many cases, yes. 3/8″ AR550 performs better against rifle rounds while reducing target weight.

When to Choose Each

Use Case Recommended Steel
Recreational pistol shooting AR500 (3/8″)
Pistol and occasional rifle use AR500 (1/2″)
Frequent high-velocity rifle shooting AR550 (1/2″)
Weight savings with maximum durability AR550 (1/2″)
