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

CORE™ BIO BBs by Specna Arms

Specna Arms CORE BIO BBs are excellent ammunition for all types of 6mm airsoft guns, including pistols, rifles, SMGs, machine guns and sniper rifles using AEG, GAS, HPA or manual power. Specna Arms is a well-known gun brand, so it’s no surprise they’ve expanded into producing their own BBs. They manufacture high-quality 6mm ammo with a precision of 5.95 mm +/- 0.01 mm, suitable even for tight bore barrels.
Each CORE BB is carefully polished to a glossy finish in the final production stage. Thanks to full production control, you get BBs with a perfectly round shape for flawless feeding and consistent hop-up performance.
BIO BBs feature a biodegradable formula that allows for faster decomposition, making them eco-friendly. On some airsoft fields, BIO ammo is mandatory.

Specna Arms BB product lines (standard, BIO and tracer)

1. ULTRA EDGE™
   Top-tier BBs from Specna Arms. The highest line made in the same factory as G&G, offering excellent quality even for ultra-tight sniper barrels. Superb accuracy with 5.95 mm (+/- 0.001 mm) tolerance and weight consistency (+/- 0.01 g). They feature special surface treatment to reduce barrel vibrations and improve contact with hop-up rubber.
   
   
2. ONE™
   High-quality BBs with great value for money. A solid compromise between ULTRA EDGE™ and CORE™ for players who like to shoot in bursts. Suitable for all guns, including 6.01 precision barrels.

3. CORE™
   Still a very high-quality ammo line at a very affordable price thanks to cost-effective production. Suitable for all barrels, with excellent roundness and smooth surface.

4. PRIME™
   A great value BB line. Compared to ONE™, they may have a slightly larger tolerance of 5.95 mm (+/- 0.01 mm), making them suitable for 6.03 mm barrels and wider.

Recommendation

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 (e.g., inside the magazine while crawling). It’s also important to regularly clean your inner barrel to prevent dirt buildup that can affect performance.
