What Do Bullet Tip Colors Actually Mean? Green, Red, Black, Blue Explained
Military ammunition uses a color-coded tip system to identify bullet types at a glance — and most civilians have no idea what the colors mean. That green tip on your 5.56? It's not "armor piercing" despite what the internet says. That black tip? It actually is. Here's the complete NATO color code system, what each type does, and which ones you can legally buy.
The NATO Color Code System
NATO standardized bullet tip color coding so soldiers from different countries could identify ammunition types without reading labels — critical when you're sorting ammo under fire. The system applies primarily to military ammunition and varies slightly between nations, but the U.S. military standard is the most commonly encountered by American civilians.
| Tip Color | U.S. Military Designation | What It Does | Civilian Legal? |
|---|---|---|---|
| Green | M855 / SS109 (5.56mm) | Steel penetrator tip over lead core. Enhanced penetration at range. | Yes — federally legal |
| Black | M2 AP (.30-06), M993 AP (7.62mm) | Hardened steel or tungsten core. Actual armor-piercing ammunition. | Legal to possess, restricted to manufacture/import |
| Red / Orange | M196 (5.56mm), M62 (7.62mm) | Tracer — burns a visible pyrotechnic trail in flight for aiming reference. | Legal in most states (fire hazard restrictions apply) |
| Blue | M781 (40mm) | Incendiary — designed to ignite on impact. Rarely seen in small arms. | Restricted / NFA regulated |
| Silver / Aluminum | Various | Reduced-range training or frangible training rounds. | Yes |
| Yellow | M48A2 (.50 BMG spotter) | Observation / spotter-tracer. Marks point of impact for crew-served weapons. | Varies |
Green Tip (M855): The Most Misunderstood Round in America
The M855 "green tip" is by far the most common color-coded ammunition civilians encounter, and it's also the most misunderstood. The green paint identifies it as the NATO SS109 standard 5.56mm round — a 62-grain bullet with a steel penetrator tip over a lead core in a copper jacket.
Is it armor piercing? No. The M855's core is approximately 80% lead. Federal law defines armor-piercing ammunition as having a core "constructed entirely" from hardened metals like steel, tungsten, or depleted uranium. The M855 doesn't meet that definition. Its steel tip was designed for improved penetration at range against light barriers (helmets, windshields, sandbags) — not body armor. In fact, the M855 has been tested against modern Level IV body armor plates and failed to penetrate.
The ATF specifically exempted M855 from armor-piercing classification under a "sporting purpose" exception. In 2015, the ATF proposed withdrawing that exemption — arguing that the rise of AR-15 pistols meant the round could now be fired from a "handgun," making the sporting exemption questionable. The proposal triggered a massive public backlash: over 80,000 public comments, 53 U.S. Senators, and over 200 House members opposed the ban. The ATF shelved the proposal and M855 remains legal to buy, sell, and possess.
Black Tip: The Real Armor Piercing
Black-tipped ammunition — like the M2 AP in .30-06 and the M993 AP in 7.62x51mm — is genuine armor-piercing ammunition with a hardened steel or tungsten carbide core. It's designed to defeat armored targets including vehicle armor and hardened positions.
Under federal law (18 U.S.C. 921(a)(17)), it's legal to possess armor-piercing handgun ammunition, but the manufacture, importation, and sale of new AP handgun ammunition is restricted. AP ammunition designed for rifles faces fewer restrictions because the original 1986 Law Enforcement Officers Protection Act focused specifically on handgun-caliber AP ammo as a threat to police body armor. Black-tip .30-06 surplus is still encountered at gun shows and online, and possessing it is legal in most states.
Red and Orange Tip: Tracers
Tracer ammunition contains a small pyrotechnic charge in the bullet base that ignites on firing and burns in flight, leaving a visible streak of light. Military crews use tracers to observe bullet trajectory and adjust aim, typically loading one tracer per every four regular rounds ("1 in 5 tracer mix").
Tracers are legal to purchase and possess in most states. The primary restriction is practical, not legal: tracers are a serious fire hazard. The burning compound exits the barrel at over 2,000°F and the trail remains hot enough to ignite dry vegetation, paper targets, and range materials. Most outdoor ranges ban tracers, and many states prohibit their use during fire season. Tracers on indoor ranges are obviously a hard no. Several western states (California, Colorado, Montana during fire season) restrict or ban tracer use on public and private land.
What About Commercial Colored Tips?
Don't confuse military color coding with commercial bullet tip colors, which mean something completely different:
Hornady red polymer tips (V-MAX, ELD-X, ELD Match) indicate a polymer aerodynamic tip designed for accuracy and controlled expansion — not incendiary. Nosler Ballistic Tip uses a yellow or white polymer tip for the same purpose. Federal Syntech uses a red polymer coating over the entire bullet to reduce barrel fouling — it's training ammo, not a military designation. These commercial color choices are brand-specific marketing decisions, not standardized military codes.
