16.5", kinda long for the wife & not a SBR so restrictions. Can u suggest something else, possibly easier to find, preferably 9mm? IWeasel, are you dead set on an AR carbine?
If not, check out the Kel-Tec SUB2000 carbine. A friend if mine has one he got last year. I have shot it several times, and it's an awesome carbine and not very expensive. It folds in half and is much more compact than an AR carbine. He keeps his in a bag that looks like a case for a laptop.
