I bought a Premier 4.5-14x44 last year. The current model. Mounted it on a CZ 527.
The gun shot great, until I increased the power and had to turn the AO. Then it would not track.
Superseal 110 was at the range with me when it happened. We both had thought maybe my BC flip ups, which were just barely touching the barrel, and I mean barely, may have been the problem at the time. However, something did not seem right to me about that theory.
When I got home, I stuck my collimator in the barrel and turned the AO. As I turned it, I watched the crosshairs wander all over the grid. I have seen this in cheaper scopes before, even a little bit on the Vortex Viper I had, but never as dramatic as on the Swift.
I only paid $90 for the scope. I also took the time to PM the guy who sold it to me, as there is no way he could not have known it did not hold zero.
I sent the scope back to Swift, and in less than 2 weeks a new one arrived, no questions asked. Excellent customer service.
I sold the new one unused for $175, as I had seen enough and did not care to see if it worked or not.
It did have excellent glass for the money IMO. USA made Schott glass.....
