Thanks for the replies.
The serial number is indeed prefixed with a P, which is like P-4....
Does this basically confirm the 1200tx model?
I know for sure this rifle is definitely not from the 80's. Because I remember it growing up. Im thinking late 60's but will know for sure later today.
Also, I forgot to mention not sure why, but this rifle is chambered in 30-06. Most of the 1200tx I have seen on the web seem to be 7.62/308.
Im taking the rifle to a local gunny tomorrow to have it checked out and ask them about doing some mount work as well.
Thanks Again,
