SBR in Georgia gets more legitimate every day with their many offerings, especially in tracers. In the order that I received from them today was a new full-color multi-page brochure showing all their stuff. Their tracers are very reasonably priced I have found.
Here are a couple newer styles from them in subsonic 9mm tracers. Shown are the 147gr subsonic standard range (green tip) and extended range (red tip) tracers:
The tip colors have also become darker and more akin to ink rather than paint, for those familiar with their original green & red tip colors:
They have several grain weights & tracer range options in most calibers. I wish they would get on with their 22lr tracer production so I can get a couple of those boxes though…
