Sitting in the shop matching parts for a G3 clone build, I noticed some things slightly odd. On a '81 POF BCG, the bolt head and locking piece had arrows etched on them. Also the bolt head had a grind mark on the top. All three main parts are electro etched with 073. This BCG has no wear on it and looks NOS. Is this type of things normal for POF or HK parts. I am not concerned by any of it just curious.

My first thought would be those are armorer's marks but could be anything; looks fairly rushed or crude.

Possibly a training aid?
