Let me repeat this very clearly. The Plastic shroud on the back of the Tikka bolt serves no purpose but that of covering the cocking piece and rear of the firing pin. If you had one you would see very clearly what I am talking about. The Shroud on every other rifle I am familiar with has the firing pin as an integral part of it and sometimes has a safety that is attached to it...Weatherby Mark V and Model 70 are prime examples. It is not a traditional shroud. The tolerances on the rear flange of the tikka firing pin assembly have no more tolerance then what is found in your run of the mill high power rifle at that point in fact it probably has less and nevermind it is held in place by the bolt handle in a precisely milled dovetail. I have owned exactly 1 Tikka rifle and do not own it any longer for my own personal reasons but safety or lack of was not one of them.
