I thinking of putting together a USMC 1903A1 sniper rifle clone for the CMP Vintage Sniper Match. I have enough 1903 parts to put together a complete rifle and Midway has the Leatherwood Hi-Lux William Malcolm 6X scope at a reasonable price. I need some info on the front ring, how its attaches to the barrel, and hand guard dimensions. Anyone have a source for this info or a list of commercial equivalents for the mounting hardware? Ed
