Frequently Asked Questions

What does the green tip on 5.56mm ammunition signify?

The green tip on a 5.56mm round indicates that the bullet has a steel core inside. This distinguishes it from standard ammunition, which typically features a lead core.

How does M855 Green Tip ammo differ from standard FMJ rounds?

M855 Green Tip rounds have a steel penetrator core for better penetration of hard targets. Standard FMJ rounds use a softer lead core, which tends to flatten upon impact with hard surfaces.

Are M855 Green Tip rounds considered armor-piercing?

Yes, M855 Green Tip rounds are officially designated as M855 and are frequently referred to as armor-piercing rounds due to the steel penetrator's ability to pierce harder materials.

What makes steel better for penetration than lead in bullets?

Steel is significantly harder than lead, as indicated by hardness scales like Mohs and Brinell. This superior hardness allows the steel penetrator in M855 rounds to penetrate hard targets more effectively than the softer lead core of standard FMJ bullets.
