Does HR mean the hopper is on the right side?

Does HR mean the hopper is on the right side of the gun? Or is that HL?

As you hold the gun and look down the length, a HR body will have the hopper sitting to the right of the gun. I'm left-handed, and when I hold my HR gun, the hopper sits close in towards my body. They used to refer to HR guns as left-handed guns.
