I have a co-worker that has an older a bolt that was not fireing. It has been hunted hard in the Rainforest areas of WA. St. I'm thinking I would start by taking a look at the bolt. I have Remington's and Winchesters . No familiar with the A Bolt bolt. I've googled it and not coming up with much ! Anyone know how to do this or where to find out. I've found diagrams but was hoping for a bit more. Any suggestions? Thanks in advance guys!
