Lancer Tactical 2850 Round Streamline Competition Grade Tracer BBs, .30g, Green

Night games have a problem: you can't see where your shots land. Tracer units solve that by lighting up the BB in flight, but they need tracer-compatible BBs to work. These are that match.

The .30g weight is heavier than the standard .20g you'll find in most entry packages. Heavier BBs hold their spin better through the hop-up, so they track flatter and resist wind drift at distance. That makes them a better fit for outdoor fields where you're dealing with open lanes and crosswinds. The trade-off is that they need a bit more power to cycle cleanly, so check your gun's minimum FPS requirement for heavier BBs before you buy.

How the glow works. These are glow-in-the-dark tracers, not chemical or battery-powered. They absorb ambient light during the day or under field lights, then emit a green glow when fired through a tracer unit. The effect fades over the course of a game, so they're brightest at the start and dimmer toward the end. For extended night sessions, bring a spare bottle and swap when the glow gets too faint to track.

Before you buy. Not every field allows tracer rounds. Indoor CQB especially tends to ban them because the glow can interfere with other players' vision in tight spaces. Check your field's rules before you show up with a bottle of tracers. You also need a compatible tracer unit installed in your barrel — these BBs won't glow on their own. If you're running a short barrel or a low-power setup, the extra mass of .30g might cycle inconsistently; test a small batch before committing the whole bottle.

2850 rounds in a single bottle. That's roughly three to four full reloads for a typical mid-cap, so this will last a regular player through several game days. The bottle itself is reusable for storage between games.
