Okay I did some trading for beautiful MT6700. I was told it was owned by a single owner prior to guy I bought it from. Total round count is 50 rounds at the highest. I did some research on Colts before I went to do the trade, so I knew prior to making the deal the BCG wasn't Colt as it didn't have MPC stamped on the bolt nor a C stamped on the carrier. However the BCG that was installed seemed to be of high quality with properly staked gas keys and it was a FA carrier. I have since purchased a genuine Colt FA BCG, and I am using the one that was in the rifle as a spare, which I needed anyway.
Last week I received my new 6920. Upon field stripping the 6920 I saw markings on the side of the hammer face and there was a H on the buffer tube. Below are pics of the hammer in the MT6700, and the Buffer tube. The hammer doesn't have the markings like the one in the 6920 and the buffer tube is void of markings except a gouged area where it comes in contact with the retaining pin. Can somebody tell me if Colt has always marked their hammers and buffer tubes? I am just trying to figure out what I have here. Please don't say " If it works who cares" because I am very anal about my firearms. I appreciate any and all help. Thanks ahead of time
