BLS is a dedicated precision BB manufacturer. Unlike general airsoft distributors who produce BBs as a secondary product, BLS's entire focus is on dimensional accuracy and surface consistency. Every BLS BB is produced to tighter diameter tolerances than most general skirmish BBs — a measurable difference that matters most in GBB pistols, precision AEGs, and high-power sniper platforms where BB inconsistency is a leading cause of accuracy variation.
BLS colour coding — what the BB colour means
BLS uses BB colour to signal the intended use case — not purely for aesthetics. Understanding the colour system makes selecting the right product straightforward:
| Colour | Weights available | Use case |
|---|---|---|
| White | Standard-to-mid weights: 0.20g, 0.23g, 0.25g, 0.28g, 0.30g, 0.32g | General skirmish and upgraded AEG use |
| Ivory | Mid-heavy to very heavy: 0.20g (coloured variant), 0.36g, 0.40g, 0.43g, 0.45g, 0.48g | Precision builds, DMR, sniper platforms |
| Gray | Very heavy specialist weights: 0.38g, 0.40g, 0.42g, 0.43g, 0.46g, 0.48g, 0.50g | Highest-power sniper platforms, specialist use |
| Purple / Black | 0.20g in distinctive colour | Speedsoft, training drills, coaching visibility |
| Green (Bio Tracer) | Bio tracer range: 0.20g, 0.23g, 0.25g, 0.28g, 0.30g, 0.32g | Outdoor night events at bio-mandatory sites |
Ivory is BLS's colour code for the mid-heavy to very heavy precision weights — the weights used by DMR platforms and dedicated bolt-action sniper rifles operating at higher power levels. At these weights, BB consistency makes a proportionally larger difference to accuracy than at standard weights: you're engaging targets at greater distances where small diameter variations compound into measurable group size increases.
Three pack formats match the lower volume typical of precision platforms: the 1,000 count bag suits occasional sniper use where one bag covers multiple game days; the 1kg bag is the practical format for regular heavy-weight users; the 25kg bulk sack is for site sniper supply programs. The 0.20g Ivory is the same weight as BLS White 0.20g but in the distinctive ivory colour — used for training drills and speedsoft contexts where coloured BBs aid visibility for coaching purposes.
Weight selection guide
| Weight | Ideal for | Notes |
|---|---|---|
| 0.20g | Indoor CQB, beginners, high-volume, speedsoft | Standard play weight — low wind resistance |
| 0.23g | Transitional outdoor weight unique to BLS | Between 0.20g and 0.25g — suits players who find 0.20g too light outdoors |
| 0.25g | General outdoor skirmish — UK standard | Best all-round balance for most AEGs |
| 0.28g | Upgraded outdoor AEGs | Better range and wind resistance |
| 0.30g | Longer-range outdoor, well-tuned hop-up | For AEGs running 350–380 FPS with quality hop |
| 0.32g | DMR, precision builds | Needs more hop-up pressure than 0.30g |
| 0.36g+ | Sniper and high-power platforms only | Not suitable for standard AEGs |
