Anyone have experience with these? Most reviews I’ve read on the net style ones have poor reviews. Ive seen a couple hard plastic ones that “click” to the side of the gun.
So whats the deal guys? Suggestions, experiences, etc. Let it rip because I want to get one or two or so.
I got the Brass Goat.
Caldwell Pic Rail Brass Catcher with Picatinny Mount and Heat Resistant Mesh
I purchased one and additional mounts to move it around

I’ve heard several folks rave about the goat, but have no firsthand experience with it personally. Link for those that are curious:
As for the Caldwell mesh bag style, I’ve found it to be horribly unreliable. It’s caused more than one jam under rapid fire on an SR-556 and seems to be fussy to line up. I gave up on it, but am too cheap to spring $40 for the goat. So, yeah… I relish in the fact I’m still young enough to be able to bend over and police my brass the old fashioned way. 
Enjoy it while you CAN, Youngbuck! 
I use the goat whenever I have the ar at the range. Saves a ton of time cuz I hate searching around for my brass. Especially when I’m doing drills and my brass is all over. 2 things that I don’t like but live with.
1, it does rub on the mag well when putting it on and taking it off. It hasn’t been any permanent marks but it is a matter of time. The company suggests adding a drop of heavy oil or gun grease, could work.
2, if the goat has a bunch of brass in it and you let the rifle hang on it’s sling, the brass can and will leak out the top. There’s a small opening. I made a flap out of black duct tape to help with that.
otherwise, it works without flaw for me.
Thanks everyone. The brass goat looks good. I seen a knockoff of it on Amazon (didn’t know it was a knockoff of anyone at the time) but it has cheap double sided tape that held a clip that secures the “box” to the magwell and everyone said it falls off. The Caldwell has good reviews. Most of the net style I’ve seen had bad reviews.
Thanks again! Much appreciated gentlemen.
