Thanks  Butlersrangers,

I forgot to add the top of the butt plate has NJ stamped in it. I am guessing maybe New Jersey National Guard, but I don't know if it would just have NJ or NJNG?

My thought is it was a shot out or corroded barrel and was replaced. When I had the site off the tapped and threaded job didn't seem up to armory specs either. I am trying to remember if I saw a "C" on the site. I will measure the barrel, but I am pretty sure it is not a Krag carbine barrel.

I had the same thought on the hand guard due to the texture and the difference in color tone.

Would it be worth it to have it rebarreled with a carbine barrel. Or would the money be better spent else where?
