It wasn't a rhetorical question since my experience with that vintage of Weavers has been excellent, but I've only owned the "straight tube" versions: J2.5x, K1.5X, 2.5x, and 3X. Wondered if the higher powered ones had some basic flaw or if they were just so common as to be boring.

Haven't used these in extreme conditions, tho. Lowest temp in the 20s and seldom in driving rain, either. And I always reserve the irons, just in case.

My own favorites of the period are Lyman All-American and Redfield "straight-tube" low powered, fixed scopes. But I won't kick a similar Weaver out of bed if the price is right, especially the K1.5X.
