Be 1RLM for 1" or 14RLM for 30mm
I have had 3 sets of them - all med high on two Mini's. The only issue I've had with clearance is with some scopes with 42mm objective end, the bell clearance is too close for the hand-guard. And I am talking about a small amount. The Mark AR 4-12 x 42 on my Mini-14 Target was one which needed just a little extra clearance. In a lot of those cases, you can file or dremel some of the top of the hand-guard off for the clearance. And the hard plastic kind of polishes up after and really doesn't look bad. The hand-guard is a cheap replaceable plastic part available from multiple sources for $15 - $20 in case you want to take it back to stock after.
