Perhaps.

Anyways, why bonking people on the head with a gun may be an immediately bad idea:

1. It can fudge a scope-mount or misalign any other gun-accessories, that may be important.
2. It can mar and damage the finish on the stock ("skull-shaped dents") and during resale, see point 1.
3. Slight possibility of damaging the rifle itself.
4. Chance of burning or shooting yourself if gun is hot or loaded.

and the most important one:

5. If you dad sees you abusing his $3,000 rifle, he's going to ground you for the rest of your natural life.
