Friends:

I have recently used a technique shown me by DocBill.

Use a Mini-Maglite, the one intended for 2 AA batteries. Costs 15 bucks at Wal-Mart. With one layer of scotch tape wrapped around the flashlight body, it is a perfect fit in the barrel of my NID 12g. The long body of the flashlight helps keep it parallel with the bore.

Dial the light to "spotlight" and use it for mounting drills as Jimmy W suggests. I stand in the living room and use the junction formed by the ceiling corner where it meets the wall corner in the dining room as an aiming point. I do this with the dining room lights dimmed down, so the flashlight spot is readily visible. The distance is about 35 feet. It will surely help you in developing a smooth mount, as that light bobbing all over the place is a dead giveaway if you are doing it wrong.

I have found the light useful also for the stock fitting - AFTER having patterned the gun and made the major adjustments such as Jim Legg discusses.
