My “el Cheapo” rig holds up under firing OK.

However, the “hillbilly wedding rings” look much better. No dimensions listed on the website, though. My concern is whether or not the split ring will slide between the vented rib and the barrel on the Mossberg.

Any ideas?

“My concern is whether or not the split ring will slide between the vented rib and the barrel on the Mossberg.”

I mounted mine on the magazine. It has the added benefit of touching the bottom of the clamp at the front of the aftermarket heat shield I installed and helps to keep it from sliding forward and coming loose. The rings that come with the clamp are 30mm. I wouldn't bother with this clamp however if you've got something working already.
