I had Adco taper pin an F marked FSB on my 20" A1 barrel. It shoots center of mass at 200 meters at mechanical zero (thank you very much). Here's my issue. When running a DD A1.5 rear sight, my front post zeros .040 below the top surface of the FSB. I know this is a minor deal but it kinda bugs me.
Would replacing my FSB with a standard one now be a straight forward job or is it a tough thing to do? |

Quoted:
Does it make any difference if it is a tappered pin vs. straight pin? I would assume you have a solid jig to perform this work, and the holes in the FSB would be drilled exactly in the same place as before, correct? It does not quite work that way, every barrel is slightly different, and sometimes FSB's are a little different from one to another. If it were that way, FSB's would interchange. No, it does not matter if it's straight or taper pins. |
