It's surprising that so few people even post about Apex scopes. Good or bad. There were quite a few of us on the first Rival pre-order. And it seemed like alot were getting the hunter and 1-10 scopes.
The owner of Apex (Envitro?) posted that the Rival was different than the Riton X7, but offered no details. So maybe the internals are different/better? The x7 is a grenade that lots of people have posted on, and there are very few/no negative Apex posts that I can find. But maybe 95% of their scopes are in sponsored shooters' hands? No idea
Overall my Rival has been good. The glass is clearer than the Ares ETR, but not quite as sharp as the XRS 2. I know the ATRS guys were claiming it had better glass than the NX8, but I have no time behind that scope.
Tracking is excellent, turrets are OK. Better feeling than the sub-$2k Athlons, gen 2 PST, Javelin etc, but I'm not a fan of the 15 mils/rev. Looks like the new ones can be had in 10 for an extra $100.
Glass wise there's very little CA, and it's pretty sharp edge to edge. The eyebox gets a bit tight past ~23x, but it's useable all the way to 32x. The zoom and parallax knows are smooth but took a little effort out of the box.
For the $1900 I paid I'm happy with it. Now that they're $2400-2500 I'd have a hard time choosing a Rival over a $2100 LOW-made Cronus.
