3 BUCC Brass Catcher Mount

thingiverse

I avoid losing brass because crafting it takes too much time, so I use a brass catcher. Over the years, I've tried different catchers, but the 3 BUCC unit performs best in my opinion. However, the plastic part that attaches to the rifle is fragile and expensive. I've included the Fusion 360 file used to create the mount blocks, which require a 4mm cap screw and nut for a tight fit. Now all my rifles are equipped with catchers, and I have some spares in my range box. Update: I added another design along with the Fusion 360 file and picture for a mount that works well with the scope mount and forward Mlok guard. Unfortunately, the stock mounting block doesn't fit perfectly but it functions well anyway.
