Service Rifle Scope on Anschutz NMAR

As a relatively new high power service rifle shooter, I found an Anschutz NMAR 8001 this last summer that I couldn't live without. Has the original iron sights and everything. However almost a decade ago NRA and CMP started allowing the use of low magnification rifle scopes that max at 4.5x.

What are some ways that people are mounting scopes on PCP air rifles that still allow for loading a pellet into the barrel?

I suppose this also applies to air rifle metallic silhouette as well
