Re: March scopes
Other companies don't offer 10:1 zoom because they can't, or at least haven't been able to yet. It's very difficult to make such a wide ratio with acceptable optics that fits in the tube of a scope. When IOR first came out with 6:1, they needed a 35mm tube and adjustment range was still limited. For their 7:1 they use a 40mm tube. Swaro and Bushnell have now done 6 and 6.5 in a 30mm, but adjustment range is very limited for the high power models. Apparently there were some Swaro Engineers at SHOT who simply would not believe March had done it until they saw the scopes for themselves. Anyway, that's why these have raised so many eyebrows--if it was easy to do, everybody would be doing it.
The warranty issue is something that people will need to look at closely. I've done a lot of buying and selling of scopes lately and so if it doesn't transfer that wouldn't be helpful. Though if it runs out after 5 years anyway it's not quite as big a loss. I would want to find out about typical repair costs, etc, before I made the plunge.
The flip side of looking at that is I was very well treated by IOR's warranty but would not risk putting another 3-18 on the 300. I'd rather not need to use the warranty. If the reliability of these scopes for typical warranty-type repairs you see with other brands is as good as some say it might not be much of an issue, especially if repair costs are reasonable.
If I smash a S&B or Premier by running over it with a truck, having a horse lay on it, or hitting it with a bat, etc, I'll need to buy a new one so it's no different there. It's really only an issue for a failure that would be caused by a manufacturing defect that wouldn't happen or you wouldn't notice in the first 5 years. Of course none of my broken IORs made it that far or even close.
So it is a strike against them and it would be nice if they could work out something better. I'd certainly get more details and talk to the benchrest guys who use them to hear their experiences if considering one.
