I just finished building a Springfield Armory M1A ( 18" scout barrel) and mounted it on a Troy Industries MCS chassis with a VLTOR E-mod stock. It shoots tight to 450 yds(I have no place to shoot farther) and runs like a champ. I also have a Nightforce 5.5x22x56 Mil-dot with it. Asking 4k for all or willing to separate optic and gun for 2k each. PM if you want the details on the optic.
