re: My son wants an airsoft rifle for his birthday...what is exactly the point?

Gamo is overrated. I've shot two. Both were very inaccurate and could not be dialed in. Get a benjamin and knock a squirrel out its shoes with open sights.

Speaking of squirrels and airsoft. While walking my dog one night, I came across a dead squirrel with numerous airsoft bbs around him. So to answer your original question of what do you shoot with it, evidently squirrel is an option.
