Congrat on the new (used) rifle Jeff. Looks like it will be a good shooter.
And BTW: you should keep your front sight sharp while the rear sight and target appear 'fuzzy'. Once you locate your target, focus on that front sight and let the target be blurred. Look at it this way. The sight is constantly moving but the target isn't going anywhere. At least that is the way an NRA firearms instructor told me to do it.
