How in the world is everyone bedding the axis receiver?

A guy dropped one off asking if i could bed it , i said I'd take a look... Man there is ALOT going on underneath so to speak lol.
I did a quick search with no luck , is there an existing thread on here pertaining to this? Stock in question is a Boyds prairie hunter (short)

I can kind of work with this recoil lug setup but the rear portion around the rear screw/trigger assy has me scratching my head lol

Thx in advance.
