Picked up a Colt 4 X 20 knock-off scope at a gun show.  With iron sights I can shoot a 1" group at 100 yds.  With the scope on I am lucky to get them into a 6" group.  Any suggestions on troubleshooting?

I know I'm gonna sound like a smartass for saying this, but it needs to be said. Don't buy knock-offs. You generally get what you pay for. The extra money spent on quality is almost always worth it.

Zero is fine, just won't hold.

The mount is crap.   That goes for the originals too.
