Frankford Arsenal is excited to introduce the re-designed Vibra-Prime Automatic Primer Tube Filler for small and large primers. This innovative device saves the progressive reloader a lot of time usually wasted on filling primer tubes. Its unique motorized agitation mechanism vibrates the primers in a primer tray working them into primer tubes within a matter of seconds. From there, the primers may be transferred into any model progressive press tube with the use of the included universal tube adapters. Runs on 2 AA batteries (not included).
