I'll get some pictures later. My sights are different, but not very different. I only have one leaf, and just like yours, there is no standing back sight. It's almost like Rieger was confused if he was making a shotgun or a rifle.
Your rifle is crossing, that means too high velocity and more than likely too light of a bullet. So at least, it goes in the expected direction.
Are L&R at least on the same plane (unlike the Fraser)?
