Need help in zeroing my Achilles

[GNV]

This is one of the faults of Achilles. While the PH Springers have a cutoff on barrel tip and a matching portion in side the front sight, the Achilles did not have such because the barrel is removable and such cutoff would be useless. Once you found the correct position of the front sight make a small indent on the barrel using a punch where the grub screw is so that you can always fix the grub screw in that position. If you ever remove the barrel always be careful to align the two barrel fixing grub screw marks correctly
