Yuppers,,, sell it and take the lose,,, or send it to 1 of the top 5 rifle builders to get it sorted,,, """find the issue""" and proceed from there...
Once the issue (s) have been detected,,, it would be wize for them to address this on their dime and the extra funds you are spending to trouble shoot the puzzle...
Let Sako know this with a friendly letter or e-mail with the problem your licenced top tear gun-smith found...
Only then proceed with action...
The other option is fork out more funds which sucks goats milk,,, if I was to run into a issue / puzzle,,, I drop my rifles off at my friends shop since he's pretty skilled at sorting things out,,, in the machining world and boots on the ground...
If he can't sort things out,,, then the world's going down... Ha
Sorry to hear that things didn't pan out,,, very rare for this in most cases,,, but it dose happen...
Good luck getting your Gunsmith friend to take over from this point as it will get sorted one way or the other...
