I picked up this super blackhawk today and so far really like it. However, after getting home and beginning to mount the scope a leupold 2x EER I noticed it came with two diffrent size scope rings a #3 and a #4 is this correct? If it is correct which one goes on the front and which is on the back? It looks to me that no matter how I mount it it either points up or down depending on which ring is in the back. Any info would be greatly appreciated. Thanks
