Hi All, I have had this rifle in my possession for a number of years. I purchased it in the late 90's, as a wooden stocked A2 forester, stainless steel barreled 6PPC USA . It has lived in a synthetic stock since then, and has delivered outstanding performance with home loads in both PPC USA and adapted 220 Russian cases. I decided recently to do some work on the trigger, as newer rifles I have have now gotten me used to a lighter trigger. I stripped the group down with the aid of a bit of heat - it had been locktited together pretty well - and examined it. the unusual thing is, it does not seem to conform with any of the other trigger groups that I have found information on so far. In the pictures, you can see that at the top of the group, a spare - or what looks to be - take-up screw has been added in an open threaded hole. This serves no other purpose other than to act as a spare to me. The forward tensioning screw for the whole group is also at an angle. This too seems to be different from the other triggers I have found information on. from the serial number 33**33 , I would age it between 1977 -82, so I would say that it is not an original factory 6PPC , as the action is too old. Possibly originally a .243 ? The tension and backlash grub screws are also slightly different to each other. I found that out when they were removed and transposed, resulting in a much better feel to the adjustment of the trigger itself. If anyone can cast any light onto this rifles heritage, I would be most grateful. All the best.
