I was trying to solve a similar problem the other week. I had a CenterPoint scope handy that I wanted to use on my MK-177 for ratting, but it only focused down to 10 yds. So after mounting, I loosened the retaining ring on the large objective and slowly rotated the lens outward until it focused down to around 12 feet, then re-tightened the retaining ring. Problem solved, and I didn't have to buy a new scope. It now adjusts between 12 and 80 feet.
For super close range can you use a red laser, mounted supper low and adjusted for close range.I have red laser sightmark on my 1322 and with the 6x bugbuster scope mounted on the gun.At close range (3 yards) I can see the red laser in the scope and use its zero to shot close and personal if needed.
