Pleasantly surprised, but slightly dissapointed - CenterPoint TAG 6-20x50mm Rifle Scope

I received my order in a very timely manner. Everything was intact. No damages or issues that I noticed. The ONLY drawback / dissapointment was the fact that I could not use the rings that came with the scope on my ATI Scope base. (They appear to be very sturdy) so I had to stay with the Leopuold rings. Which works just fine. But I was really looking forward to using the Centerpoint rings. Otherwise after my initial trip to the range this past week, the scope performed very nicely. It did not loose it's zero and was easy to get it to set up for the ranges that I was shooting at MAX 500 Yards. Very clear and presice. The only bother drawback that others have Reported and I noticed it as well . Is it doesn't seem to do well in lowlight situations. I'm looking forward to get it back out to the range and put it thru it's paces Again. BTW I Mounted mine on a Sporterized Mosin Nagant.
