BLS BBs for Every Airsoft Gun

Consistent BBs are one of the simplest ways to improve your accuracy. BLS makes its airsoft BBs to a tolerance of 5.95mm ±0.01mm, tests them for size and roundness, and polishes them with no seams, so each shot leaves the barrel the same way as the last. To find out more about the brand, read our guide to BLS airsoft BBs.

Choosing the Right BB Weight

The right weight depends mainly on your gun's power and the way you play:

  • 0.20g–0.28g: a good match for most stock pistols and AEGs. Try the 0.20g (5000), 0.25g (4000) or 0.28g (3500) bags.
  • 0.30g–0.36g: a popular choice for upgraded AEGs, gas blowback rifles and HPA builds, as heavier BBs hold their line better in wind. See the 0.30g, 0.32g and 0.36g BBs.
  • 0.40g–0.50g: heavyweight BBs for sniper rifles and DMRs, sold in bags of 1000: 0.40g, 0.43g, 0.45g, 0.48g and 0.50g.

A heavier BB needs more hop-up to fly straight, so re-adjust your hop whenever you change weight, and always chronograph your gun with the BB weight you'll use on the day.

Supreme Grade Bottles

BLS Supreme Grade BBs come in handy 3400-round bottles in 0.20g, 0.25g, 0.28g, 0.30g and 0.32g. A bottle is easy to pour from and keeps your BBs clean and dry in your kit bag.

Biodegradable BBs

Many UK sites, especially woodland sites, ask players to use biodegradable BBs. BLS bio BBs are made from PLA, which breaks down naturally over time, and come in a full range of weights, including 0.25g, 0.28g, 0.32g, 0.40g, 0.43g and 0.45g. Always check your site's rules before you play. Browse all biodegradable BBs.

Tracer BBs

Tracer BBs glow when they pass through a tracer unit, so you can see where every shot goes in night games and indoor sites. BLS makes them in three colours:

Some tracer units only light up green BBs, so check that yours works with red or blue before you switch colours.

Carry Your Spare BBs

The BLS magazine-style BB bottle holds up to 1200 BBs and fits neatly in a magazine pouch on your chest rig, so you can top up between games without heading back to your bag.
