Golden Ball ProSlick Seamless Outdoor Airsoft BBs, 0.28g, 3575 Rds, White

Most fields cap outdoor AEGs at 380–400 FPS on 0.20g. That's the baseline. If you're running heavier BBs, you're shooting the same energy at a slower speed, which means less drop and better wind resistance. These Golden Ball 0.28g rounds are for that middle ground—light enough to feed reliably in most upgraded AEGs and gas blowback rifles, heavy enough to hold their line outdoors.

The 0.28g weight sits between the common 0.25g and 0.30g options. It's a practical choice if your hop-up can dial in properly and you want better performance without jumping to sniper-weight ammo. Heavier BBs need a hop-up that can grip them, so if you're running a stock rifle set for 0.20g, expect to adjust. Once tuned, the tighter grouping and flatter trajectory are noticeable, especially past 100 feet.

Seamless finish keeps feeding smooth. The white color helps you track shots in flight, which is useful for spotting misses and adjusting quickly. The bag holds 3575 rounds, which is enough for a full day of skirmishing or several sessions of range work. BBs are consumable, so buying in bulk is cheaper per round than smaller bags.

These work in any 6mm-compatible airsoft gun, but heavier BBs demand more from your hop-up and barrel. If you're running a basic CQB setup indoors, stick with 0.20g or 0.23g. For outdoor play with a properly tuned hop-up, 0.28g is a sensible step up.
