I took this in on trade and to be quite honest I was going to keep it but I need to move some stuff in my shop and I have searched Gunbroker and others and I cannot find one exact and in this condition to even offer up a price . I want to be fair because I dont price gouge people in my shop and as stated its well used . I prefer to have them come back happy and buy other things . Its well used for sure , I was told this one was a California Highway patrol trade in but I cannot confirm that . Just looking for a fair honest price to unload it and keep my small shop moving . Heres a few pics , it is the older gray colored upper and lower which leads me to believe late 80s early 90s . Colt upper, barrel, carrier, bolt, CH . The upper does have alot of wear on the top of the handle , it looks like it has ridden in a mount of some sort and rubbed it pretty good on its left side.
