Re: Vortex opinion DOWNGRADE
First of all, very sorry to hear about your friend having a problem with the Crossfire. That's the kind of thing we all hate to hear about. I know it doesn't help with that particular hunt, but you can rest assured that our service dept. will do everything possible to make it right for you guys when you call this in (800) 426-0048.
You do have to keep in mind that the Crossfires are our entry level series of riflescopes, and are built to fit certain price points. We do feel that we've done a good job of getting as much quality into these as possible for what they retail for. They are by far our biggest selling line of scopes, and I hesitate to even guess how many thousands have been sold. For these numbers, they actually have a very good track record. Of course, along with these kinds of numbers sold, it's usually the Crossfires that get mentioned on these forums when repair issues surface. This same line of thought pertains just a bit to the Vulture binos as well - an entry level line, but very good value for the dollar spent.
Re. your 6.5-20 Viper, all Vipers are using same grades of glass & coatings, so your 6.5-20 has the exact same quality as a 2-7. Now, remember that a 2-7 will many times seem a bit sharper simply due to the lower magnification. Also be sure you're correctly using the ocular and side focuses, this is very commonly misunderstood (for example, guys will try to use the ocular reticle focus as a main image focus). Others here have explained the target dot reticle pretty well - it's not good in low light, but it wasn't intended to be. 99% of the guys buying these scopes are extremely happy with them.
Again, sorry to hear about the problems, but we'll do our very best to make it right for you !
