Re: Sako Barrel switch??
It's not quite as easy as the AI, you'll have to actually send your rifle in for the new barrel to be fitted. After that it's easy. Tell the smith fitting the new barrel not to get too crazy on the barrel torque, 100ft-lbs is fine.
If your Sako is a TRG, you can use our wrench and swap out barrels without taking the whole thing apart. If you have a Sako 85 or another, you'll have to find a wrench or make one, and most likely will have to pull it out of the stock to swap it.
