Mated to CZ 527 American and holding a Leupold VX2 4-12 AO. Small improvement over CZ rings in all ways. Notched rear ring like CZ, but slightly lower and still clears bolt handle with better fit and finish for matching scope to rifle (if using Leupold scope). Could benefit from torx bolt at receiver connection vs the flathead.
Pros: Lower, better fit and finish
