VX-6 verse the VX-6HD

Can anyone tell the difference between the older VX-6 and the newer VX-6HD
Thanks

On is 1/13th longer than the other....other than that i have no idea

HD has better glass, how much better I couldn’t say. HD also has a built in anti-cant and alumina caps. HD backwards is DH, which we all know is designated hitter. So you’ll hit with that one.

VX6HD has throw lever, Alumina Caps, CDS-ZL2 lockable turrets, better glass, and higher price tag. I’ve got a 3-18x50 and I love it.

I have a VX6 and a VX5HD. I can't tell the difference. Both are great scopes and if I needed another, I'd look for a good used VX6. Since they are pre "HD" I'd bet prices are a good value on the used side. I know I'm comparing a 50mm to a 44, but the VX6 I have gathers light just as well if not some better that the VX5 HD I have. It's hard to find, but before Leupold started marketing under the HD designation, the Quantam Optical System was a big deal and that is how mine is labelled. The glass is fantastic and I think the manufacturing process for the grinding, polishing and coatings are no different between VX6 and VX6HD.
