I just purchased a Vortex HSLR which has a capped windage turret which is great for hand carrying the rifle and sliding it in and out of a scabbard. It has a exposed elevation turret with zero stop and those two things really solve many problems.
There are a couple fellas on this site that were designing scabbards especially for scopes with exposed turrets which is a good idea. You want the turrets free from pressure. There will always be the chance of a dial rotating but developing a good habit of always glancing down and checking just as you would check the bolt when hiking making sure its locked down assuring the safety is on is easy to do and is becoming a normal for me. The windage dial on the PST is the one that would go unnoticed as there is no red line (I don't think) for a quick reference.
