Not if you use the rifle barrel idea for accurate targeting,..... during the day time of course

What you could do is use the rifle to hit to target, draw a line [ on the wall for instance ] along the rifle barrel, remove the rifle, nail a piece of wood around the line you have just drawn,.. wide enough to rest the laser beam on ,... then it could be used over and over without lining up each time, day or night, all you have to do is put the laser on the wood and switch on

`along` the line you have just drawn
