back a few dozen years ago one of the guys I hunt with purchased a well known discount scope brand ,
( brand begins with a (T) and at the time cost under $100,)
to use on his marlin 45/70 rifle, everyone in our hunt club strongly suggested,
he either buy a better brand name and higher quality scope or use quick detachable scope mounts so he could use,
the iron sights. he was also repeatedly advised to sight the rifle in using the iron sights before mounting the scope.
and yes that proved to be valid advice as the scope internals fogged so badly,
it looked like someone had filled the scope tube with a cotton ball on the third day of the hunt.
buying decent value in any equipment is seldom priced at close out or bargain basement prices
yet most of us have occasionally found that out through personal experiences.
