When I first saw your brass catcher I wanted to give you a wedgy and a noogy. It may be handy at the bench rest range but it's not doing you any good at a 3 gun match. Sorry but there is no easy way to put it. I say this with love and affection and several drinks.
This reminds me of Taymoor's first 3 gun match. He was wearing an ultra Tacticiol thigh rig triple AR mag pouch deal. The only thing it lacked was a Masingil holder. He walked up to me and Chambers (maybe) and said, "guys, I don't see anyone else wearing a sweet AR mag pouch thigh rig. Is this thing GAY?". I looked at Chamber or whomever it was and we both looked each other them back at Tay and shook our heads yes. Then we all had a good laugh together.
As my boy GI Joe said, "knowing is half the battle"
