Forgot to mention if you decide to get the CDS on your Leupold, it will arrive with a universal top turret, which does not have a stop, so you sight in your scope to your rifle first. Once sighted in, you then take off the universal turret and put on the custom dial turret. The custom dial turret has the stop at 200 yards or where ever you request it to be when you order it (Your Zero). You will need the following information when you order the custom dial; Type of caliber, bullet Make and model, bullet weight, muzzle velocity, elevation, and your sight-in or zero (200 yards for all of mine).
The approximate cost was $100.00 for the CDS to be placed on the scope and $50.00 per custom dial, so your looking at about $150.00 total. Turn around time was about one month.
