The AR15 seems very ubiquitous today. There will be a rack of them in every gun shop. Nearly every time you go to the range, someone will have one. There's likely one in ready mode in a large percentage of gun owners homes. So before the AR15 came to be, what was the go-to rifle? (Sure, most folks had a shotgun for this role, but this is a rifle forum and that would be too easy an answer, so lets ignore the trusty 12ga for this thread) I'm thinking 30-30 lever action, maybe M1 carbine. Maybe both filled the niche, with the M1 being the plinker and range gun and the 30-30 used more in the hunting and homeland defense role. Your thoughts on the subject?
