Manufacturing

Each BB is polished to a high-gloss finish and then coated with a friction-reducing layer, so it travels smoothly through precision inner barrels and works well with hop-up buckings. Full control of the production process gives perfectly spherical BBs with no visible flaws or seams, a balanced centre of gravity and no air pockets inside, which is why shots stay consistent and repeatable.

In the field

0.28g is a balanced weight between range and stability, well suited to assault rifles and general use, especially on replicas fitted with precision inner barrels. The bottle is easy to carry onto the field.
