Factory barrels aren`t bad at all...
And Blaser will get less money if they open the platform to major aftermarket parts such as barrels.
Let`s face it - Blasers aren`t the cheapish ugly rifle you need to tune.. It`s a fine piece of engineering in it`s stock variant. No round action,no soldiered bolt handle,no screw-on recoil lug,no bullshit tiny extractor made of tin...

Best regards,
