The Tikka bolt handles are dovetailed into the bolt bodies. 4 have come to my shop in the last few years that had the bolt body break at the dovetails. Not the bolt handle. The bolt BODIES!
In every case TIKKA refused to replace the bolt and they have absolutely NO warranty at all, and do NOTHING if the gun breaks and it's no fault of the owner.
I am impressed with TIKKAs accuracy and smoothness, but knowing the bolts can break and that they do NOTHING for the owner if they do, I recommend against ever buying a TIKKA
