Which Acetech tracer unit is the brightest for tracer BB's?
Bifrost(M), Brighter C, Blaster(M), and AT1000 are about the same,
and the Lighter BT and lighter R are the dimmest, though they both properly light-up red bb’s.
AT2000R is a modification part and should be used with
the Acetech Predator, Predator L, and Predator S tracer or any silencer inner space that can be put inside.
It can Support green and red tracer BBs.
