SA CORE™ Pellets 0.25g, 3000 BBs (Bottle) - White

Specna Arms CORE BBs are a reliable ammo choice for all types of 6mm airsoft guns — pistols, rifles, SMGs, machine guns, and sniper rifles alike — whether powered by AEG, GAS, HPA, or manual spring systems. Already a trusted name in airsoft, Specna Arms now brings that same reputation to its own line of high-quality BBs.

These precisely manufactured 6mm BBs hold a tolerance of 5.95mm ± 0.01mm, making them suitable even for precision barrels. Each CORE BB is polished to a high-gloss finish during final processing, and full in-house quality control ensures perfectly round BBs for flawless feeding and a consistent hop-up effect.

Specna Arms BB Product Lines

1. ULTRA EDGE™ — The top-tier line, made in the same factory as G&G. Premium-grade BBs built for ultra-precision sniper barrels, with a 5.95mm (±0.001mm) size tolerance and ±0.01g weight tolerance. A special surface finish reduces in-barrel vibration and improves hop-up rubber contact for outstanding grouping.
2. ONE™ — High-performance BBs with a great price-to-performance ratio, sitting between ULTRA EDGE™ and CORE™. Ideal for players who love holding down the trigger. A 5.95mm (±0.005mm) tolerance and ±0.01g weight accuracy make these perfect for all guns, including 6.01 barrels.
3. PRIME™ — Excellent value-for-money BBs with slightly looser tolerances (5.95mm ±0.01mm, ±0.01g) than the ONE™ line, suited to 6.03mm or wider barrels. A great fit for standard setups, LMGs, SMGs, wide-bore DMRs, HPA builds, and sniper rifles, with excellent glide and precision shape for top-tier range and accuracy.
4. CORE™ — Still high-quality BBs, made more affordable through lower production costs. Compatible with all barrels and guns, perfectly round with great glide. The surface finish is less premium than ULTRA EDGE™, but dimensions (5.95mm ±0.005mm) and weight tolerance (±0.01g) match the ONE™ line.

A Note on BB Care

BB quality and cleanliness matter just as much as your barrel and hop-up rubber when it comes to accuracy. Keep your BBs protected from dirt (for example, while crawling with loaded mags), and clean your inner barrel regularly to avoid performance issues.
