I have used several BOG products over the years, in general, they are very good for the money. It won’t be as solid as some other systems, but also won’t cost as much. Looks like that product costs less than a Hog Saddle alone, and the Bog set includes the ball head and tripod - so you can understand the basis of quality between these. That clamp won’t likely hold the rifle rock solid, but would likely be sufficient for general hunting use.
I would challenge you to REALLY understand how a tripod must be used in the field. It can be exceptionally difficult to hunt with a tripod while seated, as the shooter has to move around the tripod to change shooting angle in the field. Little shifts aren’t an issue, but swinging as little as 30* can require the shooter to move enough to startle game, especially if seated. Setting up a tripod takes time and requires movement. Tripod legs clanking together or against gear while walking/moving is another issue. I’m not trying to discourage you from using a tripod, but I’d be remiss if I didn’t share this advice so you can go into this with your eyes wide open. Too many shooters buy this kind of gear, and then realize in their first outing it’s really difficult to use in the field, especially without a lot of practice to get familiar.
