I’ve got an old M8 2.5 I’m about to stick in a set of weaver lows and put on a rail on my Henry .45 Colt.
It’s not very bright, but it will take a beating (it came off my .44-70). Found it used for the princely sum of $135.00.
It’s a tiny scope, but I’m going with a rail (EGW) because the short tube doesn’t grant much mounting latitude.
If I can get it done in the near future (been meaning to for months) I’ll let you know how it rolls.
