Yes, occasionally a case will remain dangling inside, with a part of the case stuck to it.. with very little coaxing, it falls free. I have used my first one for a bizzillion rounds, (well an awful lot anyway) and it hasnt burned through. If it did, it would be easy to repair.I haven't had a chance to try that Caldwell catcher yet. I've read where the hot cases hitting the same spot will start to melt the netting. If it does start to show signs of this happening, I don't think it will be too difficult to add (sow) a piece of leather to the problem spot.
That 3 Bucc catcher is nice. Looks more durable than the Caldwell.
I cant tell from the Brownell video, but it looks like the 3 buck units arm that clips to the rail is fixed on one end. My scoped AR would not work if that is the case. The caldwell units arm slides from one end to another, so the rail attachment can go anywhere on the rail. Then just loosen the arms screw, slid it until in the correct position and tighten. On sale, the Caldwell unit is half the price of the 3 buc...
