I had a same type of problem and went from several pins (4) to a slider sight with a scope that has a .29 fiber optic and is also a 4 x scope. I do have the sight bar out about 5 inches, but can go to 9 if needed. This setup has worked great so far, I purchased use a toxonics sight (nail driver model ) used $120 and the sight scope was $100 used off of ebay....
