I bought a Swift SR665M scope on the recommendation of a guy I trust in gun-related things. He said they were the best of cheap brands. The glass is pretty decent.
http://www.swift-sportoptics.com/rscopes_reliant.html"A versatile compact and variable scope. Especially desired by brush hunters to pick up moving objects at low powers for the wide field of view."
The scope got all milky after about 100 rounds on a 7.62x39 AR. I wrote their support.
First, they tried to convince me that I destroyed it with excessive recoil and that it was never meant for "powerful calibers". I pointed out their site makes no mention of caliber limitations, and that 7.62x39 is an intermediate caliber, and that since they advertise it as "desired by brush hunters", it can't be meant for a .22 only.
So, they issued me a number and had me send it in for warranty service along with $25 "inspection fee".
A few weeks went by. I wrote them again, asking for an update. They replied they were "working on my scope today".
A month later I sent them a much ruder email asking WTF was going on. Three days later I got a package with a scope in it.
I think I'm going to stay away from them from now on...
