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.
Oh, you're not getting off the hook that easily by changing the subject. Good try!
Still waiting for you to tell us which is the "cosmetic" shroud and which is the baffle.
When in doubt, change the subject!
