A damn good idea

I think I will have to add an NRA Laser boresight to my Birthday/Christmas wishlist.

The NRA Laser Boresight is the most accurate, easy and inexpensive way to sight in your firearm. You get on target faster because a laser light is projected down the bore of your rifle and onto your target showing your bullet strike point. Great for sighting in or confirming your zero, your boresight can be used when and where shooting is not an option.

…Simply insert the boresight in your chamber and sight in from 15 to 100 yards. Dot size is 1? at 25 yards.
