Was shooting the Akela yesterday, thought I felt air on my face the last couple of shots. Too windy today 20-30 mph. Decided to remove action from the stock, want to darken the color some. While it is out I thought I would check out how the trigger works, cocked and pulled the trigger and blew the rag I had under the breach. The air seems to be coming out around the bolt. I assume there's an oring that needs replaced. Where do I get directions?
