I had a rifle with a swing mount. It reduced my accuracy range to about 200yards, which is easily met with iron sights, thus, to me, a swing mounted scope is superfluous and as such, has no value.

Fill your boots though, if you want one, it's your rifle.

Much slimmer and happier without glass on such a rifle.

There are or can be extenuating circumstances such as mere desire or eye sight problems.
