Retro AR15 & Cleaning January 7, 2016 by Shawn Ever since I acquired this Colt SP1. I had it in mid to get some of the Vietnam era military cleaning gear to go with it. Not so much to use, but for display. I have a fairly large military display of Vietnam war era items and normally the cleaning stuff is among the other things displayed. It took a while to track down each of these thing in new mint condition, but it was worth it and it makes a nice picture of the items in common use at time the rifle was originally made.
