Uncle Mike's Magnum band swivels set is very good quality and just what you would expect from Uncle Mike. The only thing that I would suggest, is to use your own hex key wrench. The one that comes with the set is made of a very soft steel and it will bend and twist to the point that you cannot tighten the set screw properly. The other thing that would be good, if they put a piece of double sided tape inside the split ring and that would prevent slipping and scratching the barrel.
Pros: Very well made
Cons: Barrel clamp could be better but ok.
