I could sort of like the idea of a bullpup for a HD gun, easier to use in tight quarters, etc. For a general purpose rifle? ummm....
The price keeps dropping, so at some point I may try a Kel-tec shotgun.
One of the local shops has a Sig 716 pistol (yes, a .308 pistol with a 12" barrel) and the Sig brace. I suspect one shot, even a miss, would send the bad guys running.
