Colt Ar 15 Manufacture Date By Serial Number
After Colt's patents expired in 1977, other manufacturers began to copy the Colt AR-15 rifle's design. However, the term 'AR-15' is a Colt registered trademark and Colt only uses the term to refer to its line of semi-automatic rifles.
Most of the Colt 1911s I own are not in there yet. Of the ones that are there are differences from what Colt told me on the phone and what is in the online lookup database. A GCNM Enhanced I was told was made in 1996 comes up being made in 1995. I got this almost new in the box with all the papers. I can see a gun being made in 1995 and being in the supply line and then sold in 1996.
The one I found that bothers me is a GCNM in SS that Colt told me on the phone was made in 1988 but on the lookup tool it comes up 1995. Now aside from Colt telling me on the phone it was made in 1988 the friend I bought it from remembers getting it from his Son for Christmas of 1988. Unfortunately he threw out the box and paperwork years ago. It also has a collet barrel bushing, and I do not think Colt was using them anymore in 1995. The front of the frame is grooved, and, again I do not think Colt was doing that in 1995.
Not huge, but hopefully Colt is double checking the data they put into the tool. I certainly pulled that SS GCNM out and double checked the SN on the frame.
