I am getting an old M1A rifle issued to me to carry on duty. Do they still make parts so I can update this rifle to today's standards. It has an old wood stock I would like to up grade so it would not be so heavy. I am also Getting a Colt 1911 that was made in 1945 as an off duty weapon, was also wondering if they made up dated kits for one of these like new springs and night sites. Thanks for any info.
