[PAR35]

9mm is too small. If it was a 10mm or better yet a .45 the taxpayers would be spared the expense of medical treatment for a rapist.

All of those are fairly unusual calibers for rifles. The only .45 I can think of off the top of my head is an old Thompson submachine gun.

You can get AR uppers chambered for darn near any pistol caliber. Including .45 ACP.
