Which weapon has a tracer burnout distance of 900 meters?

• A. MK19
• B. M240B
• C. M2 .50 Cal
• D. M224 mortar

Answer: (B)

Tracer burnout distance is how far a tracer round stays visible in flight before the tracer material finishes burning out. This distance depends on the cartridge and tracer design. For the 7.62x51mm NATO tracers used by the M240B, the tracer is designed to burn out at about 900 meters, so beyond that you won’t see the tracer glow even though the bullet continues on. The other weapons in the list use different munitions with different tracer characteristics, so their tracer visibility isn’t defined by a 900-meter figure. In this lineup, the 900-meter tracer burn-out point matches the M240B’s typical tracer behavior.
