This should be the way your Fraser is set up, but keep in mind that there are no absolutes.

1. You'll have to pull the hand-pin as it goes through the through-bolt.
2. Remove the buttplate/recoil pad to gain access to the through-bolt.
3. Remove throughbolt.
4. Carefully, slide the stock off.

I don't recall there is a breech pin to remove on Fraser's. Also to note, that the single shots are a bit different. On those you have to remove the safety if it is of the later design with the safety on the top strap rather than the earlier version with the safety in the trigger guard.
