Stock Question

[boomer656]

Any addition information such as barrel markings, photo of the rear sight, any stock markings ?

The stock is definitely not RIA since it does not have grasping grooves. Any markings on the muzzle end of the barrel behind the front sight?

I took a number of pictures earlier today. Some of which I know what they are, some I have guesses. I didn't get a full image of the rear sight, but I will do that if something can be learned from it. In addition to the markings behind the front sight, I have included an image of a mark on the barrel bottom (inspection?). I've also included a picture of the receiver left side showing the additional gas relief that has been drilled in. Also some of the marks on the receiver bottom.

Images of the marks on the stock are from the left side and the bottom. I could not discern any markings on the right side of the stock. I forgot to get a picture of the butt plate which is a smooth plate that has had chisel marks punched into it.
