BB weight vs Range

[AlphaBear]

I read somewhere that ASG manufacture their own BBs too. It was on some blog somewhere but then again anyone can write a blog eh and claim whatever. In terms of how many OEMs there are, 3 has always been the so called number floating around as @Adolf Hamstermentioned above. One in Japan, one or two in Taiwan (BLS and ???) and now maybe ASG in Europe. Also different finishes are applied to different brands which correlates to better performance and higher prices which would explain why these few OEMs can produce different lines of BB quality.

From what I vaguely recall was about three or four in Taiwan. Something like BLS/G&G/others like Airsoft surgeon.

With regards ASG think they are manufactured in the East and then "processed" in Denmark.
