A guide to airsoft tracer BBs
Tracer BBs are made from a glow-in-the-dark material. When they pass through a tracer unit, its light charges them and they glow as they fly, leaving a visible trail that shows exactly where your shots are going. They're at their best in low light, which makes them a favourite for night games, dark CQB and indoor sites.
How tracer BBs and tracer units work together
On their own, tracer BBs look much like ordinary BBs. To make them glow, fit a tracer unit to the end of your barrel. Most are built into a mock suppressor or flash hider, so they sit naturally on your gun. Every BB that passes through is charged and lights up downrange. Browse our tracer units to find one that fits your gun.
Green, red or blue?
Green is the most widely used tracer colour. Red and blue are a great way to tell your shots apart from your team's, but not every tracer unit lights them up well, so check that yours works with red or blue before you switch. Our BLS range covers:
- Green: 0.20g and 0.25g in bags and 3,400-round bottles, and 0.28g in a 1kg bag
- Red: 0.20g in 5,000-round bags and 0.25g in 4,000-round bags
- Blue: 0.20g, 0.25g, 0.28g and 0.30g in 3,400-round bottles (2026 version)
Biodegradable tracer BBs
Many UK sites, especially woodland ones, only allow biodegradable BBs. BLS biodegradable green tracers come in 0.20g (5,000 rounds), 0.25g (4,000 rounds) and 0.28g (3,500 rounds), so you can play night games and still keep to a bio-only rule. See all our biodegradable BBs.
Choosing a tracer weight
Pick your tracer weight the same way you would any BB. 0.20g and 0.25g suit most stock AEGs and gas pistols, 0.28g suits stronger AEGs and gas guns, and 0.30g suits upgraded rifles that can lift it. If you swap between tracers and your usual BBs during a game, stick to the same weight so your hop-up stays set. Our 0.20g to 0.28g BBs and full range of airsoft BBs, with its weight chart, can help you choose.
Tips for using tracers
Keep tracer BBs in their sealed bag or bottle until you need them, and store them somewhere cool and dry. Tracers really come into their own in darkness, so save them for night games and dark buildings rather than bright daylight. As with any BB, never reuse rounds you've dropped, and check your site's rules on power, BB type and weight before you play.
