Hello everyone, Just joined and have a ?. I recently just joined a gun range and when I took out my Ruger Mark 1 several guys said "That is worth a lot" So I did a little research and found out only 2100 were made of my MK1T514 5.25 Tapered Bull barrel. I have owned it since the 70s, and any info would be appreciated. No I do not have the original box. Thanks to all
