This one works amazing. Has a adjustable quick release that mounts to the picitinny rail and also is vented to let the heat out. I have them on all my ar’s and some of my bolt guns. No jams ever. The top is a hard plastic unlike the soft droopy net ones
Caldwell works and it is cheap . Just my two cents Tommy McLooking for a 223 brass catcher for a AR, anyone using one?
