It might be interesting to see what kind of junk we've all owned at one time or another. You know - Trashco, BSA(Bad Scopes Anonymous), etc. Come on, you've got to admit that most of us at one time bought at least one form of crap before wising up.
For me, BSA wins hands down. I once bought a brand new BSA 30mm Red Dot scope for $30. I suppose that should have been a wake up call on its own. Anyways, the thing never would center on my target @ 25yds. It was mounted on a Colt 1911 with a B-Square mount. Long story short, upon examination, I noticed the windage screw hole was shaped like an oval and the threads were catching the adj screw on 2 sides only. This thing came fubared from the factory. I was lucky enough to take it back for a full refund from the local sporting good shop. Needless to say, I will never own anything with the BSA name on it again.
