Things I liked:Did'nt really like anything about them. They fit very loose in my .22 Whisper. One actually fell out while closing the barrel. One group of 5 shots, were all over the place. I was shooting at a trap with a 3 inch target. only one pellet hot the target, the rest were all over the place. 5 shots in a 6 inch circle is not good at all. Things I would have changed:Larger skirts, maybe that would help.
Things I liked:Good quality and color match. Opens up with the spreader option and centers on the 13mm dovetail of the BSA Lonestar. It then leaves you an 11mm base to attach the readily available 11mm rings.
