Not sure Ive seen a direct tube mount anywhere before, seems when I have it was often attached to the rings (Hawkins i think?) or occasionally the rail. Now I'm curious. Mind expanding on that?

For lack of a better description Ive been very centric to an ar15 bubble & I know absolutely nothing about bolt guns or precision shooting. Not that I will claim to know much about any of it but this is completely new & I'm interested in theory just as much as anything else.

Sometimes I over-think & I know it, but I'd rather ask now than burn range time & yup, this thread is d/evolving more than I meant.
