This tip is available in very limited quantities for the player that wants the absolute shortest profile using an Apex II on a Big Shot Assault or Str8Shot barrel. The special metal ridges built into the tip allow optimal use of the BT Apex Tip. Full functionality of the tip is possible, including 360º rotation, optimum accuracy through perfect concentric alignment, and secure tip mounting to the barrel. Don’t settle for partial functionality due to a home-made electrical tape modification. Works with BOTH Apex 1 and Apex 2 tips.
