for lack of knowledge.
I have completly disassembled rifle except for this piece. I made a puller and gave it a half hearted try, but not being completly sure this is the corect why to remove it I did'nt push the issue. I removed the pins from the front sight, but it looks like there is another pin in the front, which leads me to believe both units don't have threads. Can anyone adivise? I am a machinist with a complete shop at my disposal ( At lunch of coarse).
