I thought you guys dropped rifle in your agency follow-on course. Are you saying that FLETC dropped rifle and shotgun as well? That'd be a real shame, since every LEO should at least have that familiarization on a pump shotgun and AR-15 even if just for the purposes of knowing how to make safe those platforms when encountered in the field....and the majority of FLETCs client agencies (as measured by number of agencies like all the random OIGs, not number of students) will not offer that training since they don't have rifles themselves.
I remember the shotguns being regular 28" barreled 870s that looked like something out of Cool Hand Luke, and the AR15s were some odd junk brand like Double Star or Hesse, along those lines. No government contract Colts or FNs.
