Here's some pictures of the internal parts. I see two things so far that might not be right - the hammer spring and the staking of the gas piston nut. I'll try cleaning the area around the nut and getting a better picture. I hope to disassemble the bolt later today. Please comment about the two items I have in question and/or anything else you see that may, or may not look "right." If those stock numbers are Julian, do they have to do with the date of the whole carbine or just the stock? Thanks! - Bob
