This ASMR video demonstrates the installation of the CTM Tac AAP-01 FUKU-2 Baby Shark upper, which is produced in long and short configurations. The CNC-machined unit includes integrated top and bottom Picatinny rails, an internal red dot slot, and a multi-brand optic adapter. Design specifications include a shark-shaped ghost ring, an open top port for TDC Hop-up compatibility, and an unthreaded compensator that does not accept tracer units.
