Yes it's similar to the hog/pig saddle just RRS design/manufactured/quality. Locks into the Anvil if you get it with the ARCA rail. You could use whatever clamp you'd like as long as it has an ARCA plate on the bottom. The RRS just looks to be a better solution to me.
I don't understand all the kickback to having the option of running pretty much any rifle on the tripod whether it's yours or a hunting buddies. Vyce isn't instead of ARCA for me, it's in addition to. If the rifle will take a rail that would be the best way. My chassis has the ARCA. The finer stocks as well as hunting buddies, etc. could still use the support.
