Mostly the bent lever. The handle end was hitting the stop before the working end moved everything into proper alignment. Then filing down the too long carrier screw, replacing the missing link pin retaining screw and the wrong finger lever pin retaining screw were mostly fine tuning the internal geometry.
Replacing the wrong magazine tube retaining pin doesn't affect the working, but probably would affect accuracy as the correct (longer) screw passes right through the diameter of the plug and mag tube and seats in a stopped hole in the bottom of the barrel, preventing the magazine tube from flexing from side to side when the gun is fired.
I thought that wouldn't matter since the magazine wouldn't flex until the bullet had left the barrel, but I guess there is 'barrel resonance' as soon as the bullet leaves the chamber, so presumably there would also be 'magazine resonance' as well if the magazine weren't fixed to the barrel. I guess fixing the two together would also help reduce barrel resonance. So a double hit on accuracy if they are allowed to flex independently.
I have to glue in a piece of hardwood where I cut the tang slots in the stock too deep. Do a little fine fit-and-cut-and-repeat until the stock to receiver gap is closed. Then I can re-drill the hole for the tang screw.
Then out to the range to make some holes in paper!
Went by the road into the range yesterday. The trucks are still running and churning it to mud. They don't even have the decency to drive on the high spots left by the truck ahead of them. The height from the road to the rims is more than the distance from the road to my frame! Once I get into one of the ruts my car would be bottomed out. (They are hauling in dirt to build a berm to give us a 300 yard range.)
