The ball head conversion I did on my Bog Deathgrip worked really nice. Worked great with all optics & every rifle- except for my PIG AR10. Original ball was rated for 33lb but I really had to crank it down TIGHT to hold the 19lb bastard. I ended up ordering in a much larger ball head assembly. 54mm ball with a 77lb load capability, MUCH better! Please don't stare at my balls long, I'm self conscious.....🤣
