SA EDGE ULTRA™ BIO Pellets 0.28g, 3500 BBs (Bag) - White

EDGE ULTRA™ BIO BBs by Specna Arms

BBs from G&G are considered among the best airsoft ammunition, but the SA EDGE ULTRA™ series takes it even further. This is the highest quality ammo produced by Specna Arms, made in the same factory as G&G BBs. The EDGE ULTRA™ line was developed to meet the demand for elite-grade BBs that suit the capabilities of modern airsoft guns.
Each batch undergoes rigorous quality control, focusing not only on dimensional accuracy but also on surface polishing and glide to achieve a maximum and consistent trajectory, ensuring every shot delivers peak performance!
EDGE ULTRA™ BBs feature a special surface finish to reduce internal barrel vibration and to enhance contact with the hop-up rubber—perfect for R-HOP, FLAT hop, and even traditional hop rubbers with a nub.
So if you want the very best for your gun, if you want to shoot farther and more accurately, and if you want to hit your targets consistently, then EDGE ULTRA™ BBs are your path to victory.
Due to their composition, BIO BBs have a higher decomposition rate, so they are more environmentally friendly than classic plastic BBs. On some fields or arenas, the use of BIO ammunition is mandatory.

Specna Arms BBs Product Lines (Standard, BIO, and Tracer Version)

1. ULTRA EDGE™
   The best BBs from Specna Arms. Produced in the same factory as G&G, offering elite performance for ultra-tight sniper barrels. Exceptional grouping thanks to 5.95 mm (+/- 0.001 mm) size and weight tolerance (+/- 0.01 g). Special surface finish reduces vibrations and improves hop-up rubber contact.
   
   
2. ONE™
   Premium-grade BBs with a great value-to-performance ratio. A sweet spot between ULTRA EDGE™ and CORE™. Perfect for all guns including 6.01 mm barrels, thanks to size 5.95 mm (+/- 0.005 mm) and weight tolerance (+/- 0.01 g).
   
   
3. CORE™
   Still very good BBs with affordable pricing. Suitable for all guns and barrels. Perfectly round with excellent glide, though the finish isn’t quite as premium as higher models. Still, they maintain 5.95 mm (+/- 0.005 mm) size and (+/- 0.01 g) weight like the ONE™ line.
   
   
4. PRIME™
   A high-value option that balances quality and cost. Compared to the ONE™ and CORE™ lines, these may have slightly more relaxed tolerances 5.95 mm (+/- 0.01 mm), making them perfect for 6.03 mm or wider barrels. Great for standard barrels, LMGs, SMGs, DMRs, HPA, and snipers. Excellent glide, shape, and surface finish.

Recommendation

BB quality and cleanliness are crucial—just like having a good inner barrel and hop-up rubber—for precision shooting. Especially when using tightbore barrels, protect BBs from contamination (e.g., in your mag while crawling), and clean your inner barrel regularly to maintain accuracy.
