Leupold VXlll 6.5x20x40 EFR

[carden1]

What is the difference between a Leupold VXlll 6.5x20x40 EFR and Leupold VXlll 6.5x20x40 EFR air rifle scope? Or are they basically the same scope?

Pretty sure the air rifle scope is more robust internally to handle the air rifle recoil shock. Seems I’ve read it somewhere, maybe on Leupold’s site.

Single-piston spring air rifles have a unique recoil profile - the usual rearward impulse as the pellet is fired, followed by a reverse kick when the piston hit the stop. Many scopes couldn't handle that, which led to special designs for that purpose. With PCP rifles it's a non-issue, and modern scopes are more robust than older designs. I'd expect a recently-designed scope to be fine on a springer. There were also a few dual-piston springer designs that compensated for the piston impulse, but they were complex (expensive? unreliable?) and soon replaced by PCP rifles IIRC.
