In this guide, we’ll cover everything you need to know about M855A1 — what it is, how it compares to traditional M855, who should use it, and what to look for when buying online.

What is M855A1 Ammo?

M855A1 is a U.S. military-developed, enhanced performance round (EPR) that replaced the older M855 green tip in most U.S. military service rifles. Designed to improve upon the weaknesses of its predecessor, M855A1 offers:

• Better accuracy out of 14.5″ carbine barrels and standard 20″ rifle barrels

• Superior performance against barriers like glass, sheet metal, and masonry

• More consistent terminal ballistics (i.e., better stopping power)

• Lead-free projectile (environmentally friendly)

Key Specs:

• Caliber: 5.56x45mm NATO

• Projectile Weight: ~62 grains

• Projectile Type: Copper core, hardened steel penetrator

• Velocity: ~3,020 fps from a 14.5″ barrel

• Penetration: Superior to M855, capable against hardened targets

Why Buy M855A1 Ammo?

1. Unmatched Barrier Penetration

M855A1 shines where other 5.56 rounds struggle. Thanks to its steel tip and harder projectile design, it punches through barriers like car doors, windshields, and even some body armor better than standard FMJ rounds.

2. Improved Accuracy

Designed with modern carbines in mind (like the M4), M855A1 offers tighter groups, even when fired from shorter barrels. This makes it ideal for tactical use, home defense, or precision shooting at medium ranges.

3. Superior Terminal Ballistics

The enhanced design leads to better fragmentation and more devastating wound channels. That means better performance in real-world self-defense situations compared to older military rounds.

4. Environmentally Friendly

Because it’s lead-free, M855A1 is often allowed at ranges where traditional ammo isn’t. This makes it a great option for shooters who want to minimize environmental impact.

M855 vs M855A1: What’s the Difference?

In short: M855A1 is the M855 evolved — stronger, faster, and more effective across the board.

Who Should Buy M855A1 Ammo?

M855A1 is a smart buy if you:

• Want military-grade performance

• Need better penetration through barriers

• Shoot short-barreled rifles (SBRs) or carbines (14.5″ or 16″ barrels)

• Plan for self-defense or home protection scenarios

• Participate in tactical shooting competitions

• Are prepping for emergency situations

It’s not just for military enthusiasts — it’s for anyone who wants the best from their 5.56 rifle.
