Replica BB guns don’t have the orange “toy gun” tips.
That’s because they’re not toy guns. They’re real guns of limited power.
Replica BB guns are often made to duplicate, as near as possible, the feel, weight, and look of the guns they mimic, because they’re used by shooters to practice handling the real thing, without the expense or danger of real-caliber ammo.
This also makes a BB-gun replica of a cop’s service weapon perfectly defensible. Why, he uses it for practice, of course.
It’s much safer for the cop than carrying around an unregistered, untraceable taped-up Saturday Night Special.
