They are GREAT BBs. I bought them for my UTG Mk96 and I don"t miss a shot. These BBs have really good wind resistance and are best for guns 350-450 fps.
No BBs were make incorrectly ex half BBs (have had it happen before).
Very good wind resistance
It comes with allot (if your a sniper, that is).
Doesn't lower your fps much more than .2s
Nothing that i can think of. These BBs are awesome.
