Well I home tuned my Big Cat this afternoon Deburred all of the sharp edges and they are all sharp edges. Filed the spring ends smooth. Polished the guides and compression chamber . Cleaned everything up and lubed everything by the book.
Found that the main spring has a slight kink and the piston seal has a nicked area directly in line with slot in the bottom of the tube. Since it was shooting OK, I reassembled the rifle and will now order some after market piston seals and another spring. This maintenance really made a difference in the way the AG sounds when fired (twang is gone) and everything is so much smoother. It was really nasty inside.
This is my question? In which direction does the bolt turn to remove the barrel assembly from the compression tube?
I tired left to loosen but it refused to budge. I then tried to the right direction , no movement. I feel that I used enough reasonable torque that the bolt should have broke free. I stopped when I noticed the torx bit failing ( actuallly 2 bits). Do I need some sort of impact driver? What suggestions are out there. I don't want to strip the bolt.
