SA CORE™ Pellets 0.25g, 4000 BBs (Bag) - White

Specna Arms CORE BIO BBs are excellent ammunition for all types of 6mm airsoft guns — pistols, rifles, SMGs, machine guns, and sniper rifles alike — whether powered by AEG, GAS, HPA, or manual systems. As a well-known name in airsoft guns, it's no surprise Specna Arms has expanded into producing their own high-quality BBs, manufactured to a precision of 5.95mm ± 0.01mm and suitable even for tight-bore barrels.

Each CORE BB is carefully polished to a glossy finish during final production. Full production control ensures perfectly round BBs for flawless feeding and consistent hop-up performance.

These BIO BBs feature a biodegradable formula that breaks down faster than standard plastic, making them an eco-friendly choice — and a requirement on some airsoft fields where BIO ammo is mandatory.

Specna Arms BB Product Lines

1. ULTRA EDGE™ — The top-tier line, made in the same factory as G&G, offering excellent quality even for ultra-tight sniper barrels. Superb accuracy with 5.95mm (±0.001mm) tolerance and ±0.01g weight consistency. A special surface treatment reduces barrel vibration and improves hop-up rubber contact.
2. ONE™ — High-quality BBs with great value for money, striking a solid balance between ULTRA EDGE™ and CORE™ for players who like to shoot in bursts. Suitable for all guns, including 6.01 precision barrels, with 5.95mm (±0.005mm) tolerance and ±0.01g weight consistency.
3. CORE™ — Still a very high-quality line, made more affordable through cost-effective production. Suitable for all barrels, with excellent roundness and a smooth surface. Though not as premium as ULTRA EDGE™, these match the ONE™ line's 5.95mm (±0.005mm) precision and ±0.01g weight consistency.
4. PRIME™ — Great value BBs with a slightly larger tolerance than ONE™ (5.95mm ±0.01mm), making them ideal for 6.03mm barrels and wider. A strong fit for standard setups, machine guns, SMGs, and wide-bore DMR, HPA, and sniper builds — with excellent glide, shape, and finish for top accuracy and range.

A Note on BB Care

BB quality and cleanliness, combined with a good barrel and hop-up rubber, are crucial for accuracy. Especially with precision barrels, protect your BBs from dirt (for example, inside the magazine while crawling), and clean your inner barrel regularly to prevent buildup that affects performance.
