I bought an A.R.M.S. 2 mount which fits the top of the AR15/M16 carrying handle back in the late '80s/early '90s from Colt. It has the ARMS logo and the Colt Horsey logo engraved as well. I mounted it on an A2 safe queen and put a Leupold on it. The mount is in excellent shape and is isthe same configuration as current production. It is an ARMS/SWAN Universal NATO STANAG/Weaver mount that secures to the carryhandle by a self-locking thumbnut and has see-thru channel for iron sight use. This is quite the collector's piece because it was a Colt product they used for the Delta series. I was able to purchase it seperately from Colt LE sales at the time.
I have pics to email you if wanted; just not sure how to post them. Shipped to you via USPS Priority for $60. Thanks
