Trying to sight-in a 6' Huntsman, hits 3.5" high @ 25yds, using CCi SV.
Can't lower rear sight, stops about 0.013" high and narrowest gap.

Appears rear sight base got WHACKED and adjusting screw might be bottoming short from full down.

OD of screw indicated that might be #2 screw but could be either -54 or -56 tpi?

Anyone know for certain??

Thanks
