Some years back I had that same Premier 4-12. For only $105 it was worth trying. Used it once and it was the worst scope ever. Scanning an area, everything changed shape like a funhouse mirror. Bright doesn't matter when the the glass is terrible. I didn't even bother returning it, gave it to a friend who had a Swift with a broken the reticle......he agreed that this scope was complete crap. Some people like them. Maybe some Swifts are actually ok, maybe mine was the exception, maybe they're better now, who knows. I'd never waste another dime on one of those things.
