About a month ago I came across a forum that someone was asking about how to catch links from the Shrike (I don't have one but I do read post about it) and someone mentioned using a brass catcher. So I started looking up someone brass catchers online and I came across one at http://www.tacticalbrassrecovery.com/
I read the reviews and I like how it would allow me to view the chamber and also allow quick access to it and the capacity was listed as 120 cases. Something the other brass catchers didn't have or do. So I bought one and today was my first time out.
It attaches to the forend picatinny rail, so it can't be used with a standard handguard forend unless you put a rail attachement for it to attach to. The attachment fixture is a clamping type not a slide on so it will fit all the railed forends that may have different measurements.
So after putting about 850 rounds down range today, I have to say I LOVE this brass catcher
. It didn't come loose at all. It can handle rapid firing. I was able to shoot 4 30 round mags with out having to empty it. It was easy to empty it onto the table and then just swipe all the rounds into a bucket. I had about 1-3 rounds that fell between the gun and catcher and just dropped to the ground so it had a 99.6% catch rate. And of course had access to chamber anytime I wanted.
Of course be aware not to turn the gun far enough to the left while there is brass in the bag with the bolt locked back or you could end up with a spent case falling into the open chamber. FYI this happened to my dad today, who isn't very proficient with the AR15/M16 platform.
It is a little pricey at about $80-$90, but it wasn't the most expensive one I came across while looking for one.
I do recommend this if you do like to save your brass, ie to re-sell or for reloading.
So here are some of my own pictures of it, there are plenty more on the company's website.
This picture you can see me pushing it back away from the chamber and you can see down inside the bag.
How it is normally attached and ready to go.
