The piston seal screw has seen better days and is a replacement. The seal looks good.
That screw is wrong, I’m surprised it even held on at all.
The breech seal is ok.
Notice the barrel is a rifled brass liner.
I found a good candidate for a replacement screw, but it needs a shorter head.
Chucked in an arbor.
A replacement spring, two less coils, same diameter wire, a lot less curvature… Then reassembly just as disassembly, in reverse. I lubed everything, lightly.
Again, note the need to rotate the trigger block when assembling.
Just for posterity.
The butt plate. Note it says IZh (in Cyrillic) rather than Baikal. I wonder why we call it an IJ-22? Just a Blue Book oddity, or some romanization of Cyrillic?
The rifle shoots! Quite powerful for its size although it may be dieseling a little due to the fresh lubes. I still need to sort out an issue with the rear sight, chrony it and check accuracy. I may lightly refinish the stock, or just re-oil it, not sure yet. I really love this rifle. More to come, later on.
