No one reputable making SCAR barrel assemblies yet.In the spirit of conversions, does anyone know of a business or smith doing custom barrels for our SCARs? I reeeaally want a 260 Rem or a 243 win barrel for mine. I think I could part with my 16 if it were available. Would any other adjustments have to made to maintain operational integrity, i.e. gas block, return spring etc?
