a .22 or a 410 is one thing but I think a AR-15 is a wee bit over the top. The girl is 11yrs old.
Why? Does the AR-15 have some special form of mind control powers that will cause her to go on a killing spree? Residue from the relentless, virtually fact-free gun control assault on military style semi-automatic rifles from nanny state politicians and the media?
Her and her father have made a fun challenge out of an involved process -- something that tests manual dexterity. And she does a good job (probably even beats dad) and is proud of her success and the approval from her father. What's wrong with that? It's probably her gun anyway and what better way to get involved in the maintenance.
Not that's I'd ever give my son an AR-15 when he's 11. I already bought the M1 Carbine and maybe a CMP Garand too. And if he likes to quickly disassemble and assemble the carbine he can do mine, while he's at it, and then see how fast he can get the fouling out
He's 2 now, and while he's not into shooting yet he is enamored with the lawn mowing process -- another tradition I plan on encouraging and passing along to him at about age 11 or 12. Go son go, mow that lawn
