Bullshit...the plastic "cork" as you call it is just cosmetic. Obviously you have not taken a bolt apart or you would not be spewing this nonsense.
The back of the tikka firing pin assembly fits in the bolt with minimum tolerance, that makes the bolt safer not the plastic shroud.
There is no problem with gas traveling up the leftside bolt rail since there is a precise fit between shroud and the receiver.
Still waiting for you to "spew" the frijoles on this magical shroud. First its cosmetic, then its a safety baffle?
Amazing!
Or, just come back with more insults, assumptions, irrelevant questions, and worthless comments? We're a wealth of information and a class act OEH.
