Of the buckings you tried, what was your favorite? I have a AAC21 that I recently picked up to make a backyard plinker out of. Put a ML crazy jet 500mm with a ML MR.Hop silicone. It seals really good and it's consistent when holding the rifle level, but I get odd behavior with pointing the rifle up or down causing more or less hop. I'm wondering if the hop up nub (default is a horizontal plastic bar with TDC adjustment) has something to do with this. There's a concave nub that action army makes for this specific platform, I'm wondering if it would be worth a try or if I just should drop in a different bucking.

Edit: Seems to be bedding in a little bit better after a few hundred rounds fired. We'll see if this holds out...
