Forgive me if I tell you straight up that I don't believe you. I've done much worse than that to them with no troubles. If you want to bet me the price of the scope, we'll buy one and I'll let you drop it 10 times from an upward standing position on to solid concrete and I say you can't bend the tube at the tube junction. I'm game if you are. No B.S.
The VXII may be the top selling scope in America. There are TONS of them out there. Never heard of a tube failure yet. If you were to strike it hard enough to bend the tube on it, you would undoubtedly damage internals also. A one piece tube would be no exception.
Yes, optics have come along way, recently. Lots of cheaper scopes have nice looking glass now. I was never a fan of Vari-XIIs. Don't even own one any more. Very tough scopes with mediocre glass. The VXII, however, has multi-coat 4 and is easily better than a Prostaff, and slightly better than a BM, glass wise, IMO. Both being around 92% light transmission. The Leupold has better contrast and eye relief though, IMO. Also tougher with a better warranty/customer service, IMO.
The part that some don't seem to get, is the Leupold is far better internally. Tougher, more repeatable. If it's not, they'll make it so within 2 weeks time.
I've had a few Monarchs, and don't have any real complaints about them. They've been tough, repeatable, and have good glass. Turrets could be a bit better. So could customer service, from what some have told me.
I'd love to see some of the other brands try to pass the tests Leupold puts their scopes through. Guaranteed MANY would not be up to the task......
