I think thee best brass catcher I have seen to date, but sad to say they are dedicated to AR10s and AR15s is the Brass Goat. I have one on a AR10 6.5 and it crazy great you can dump a 10 round mag and not snuff it or jam because of a bounce back and its stream lined so its not interfering with any visuals. I might have to look at what it would take to convert it to my bolt gun because trying to find all the dang brass on some of the stages can be a distraction or not even possible due to time restraints and good brass is painful when lost.
