Quite so-no one 'needs' a bmf activator, or an extended mag for a .22. It is, as you indicate, a bad idea on all kinds of levels. But the 10/22 dress-up game seems to flourish-folding stocks, ventilated forends, flash suppressors. I suppose the charger is ruger's way of adopting the mattel marketing strategy for Barbie dolls-when sales go flat, add a ken doll. Awhile back, the folks manufacturing the AR-7 survival rifle offered a handgun version on the same action. Looked a little like a broomstick mauser. As I recall, AR-7 's only ate standard velocity ammunition, which seems unfortunate. At least the ruger creation has a good mechanical foundation.
