6xc rifle advice

[Tom-D]

Hey guys so im looking to get a 6XC and my original plan was to put it together on a tikka action. but recently i found some one selling a Sako l579 that has been rebarrelled with a lothar barrel in 6xc. it also comes with a 3 die set of redding dies and all new norma brass and a stack of berger 105s for pretty much the same price as new stock standard tikka lite. Seems like a good buy and from what i have read its a quality action but I'm worried about after market support on an older action like this. I wouldnt want to keep it in the sporter style stock but dont see many other options for it without knocking up something custom and there isn't many scope mount options either.
Anyway curious what some of you guys would do?
