I watched the new review of the Super Sniper 5x20 and with respect to the design of the turrets I see that they are pretty beefy, do the turrets slide down over a geared spline like the Bushell Elites and Weavers or do they tighen similar to to the Leupold when your reseting them to zero? I could not tell from the video. I hope my question makes sense to the reader.
