Most of the ones I have seen that attach to the rifle might have issues with ejection and completely catching the brass. There is one from leavenotracear15 that looks to be one of the better ones but it is around $150, more than I would spend. You could probably rig up a net or box and put it on a stand next to you to catch the brass that way, or if your rifle consistently ejects in a certain area, place a box there and let the brass fly in. It seems weird to me that the range doesn't like you to police your own brass.
