Javelin BB's. .20's. I put them through stress tests. The perform fine as a low fps cqb bb. Good value for me. I run a low fps field. heh.
Least expensive BB at ASGI.
Good value for those who play CQB indoors.
Very good polish.
Diameter is within specs.
As accurate as matrix/agm/any other brand .20's
Overall, they are great.
These are not for everyone. It depends on your use, where you play and the type of face protection you require.
I tested against a few other brands. The results were: BB's did not pass a bite test. i used pliers to check (not my teeth). The matrix, King arms and ICS bb's passed. Passed being they pancaked, not broke. The javelin BB's did not pass, they cracked in half and broke into pieces. They did NOT explode like crossmans however, so I deem them safe enough for my uses.
BB's break when they hit anything @ 300-350 fps.
Anything over 350 is not recommended.
i would assume the .25's share similar traits. I will review them when I can.
