Just to tease Michael.
It's my viewpoint that the AR platform, while a great and brilliant machine, is not the longest running military rifle. That little bit of history goes to...
The lever action rifle.
Why? Well it was created and pressed into service during the Civil War. You can argue that it wasn't handed out by the army, but it was highly recommended to have the soldier buy one and use it instead of the issued rifle. Whole platoons had them as their arms during the war.
The lever action rifle was also pressed into duty during WW-1 when soldiers were ordered to protect resources needed for air support. Spruce trees. While not used on the front line the 1894 model in 30-40 was issued to the soldiers doing this job.
While this was happening here, over in Russia, the 1895 lever action was used on the front line until being replaced by the Mosin-Nagant.
So while the AR is the definite longest running modern rifle platform in the military, let's not forget the legnth of role the lever action has had in our military as well.
See. I listen to your podcasts Michael.
