I bought a brass catcher from Tacticalbrassrecovery.com for my XCR, very nice piece of kit. It has a couple of good features, you can see your ejection port if you have any stoppages without removing the catcher and the catcher folds flat while still on the rifle for storage or the model I have also has the throw lever mount for quick on and off if desired. It is hard to beat the UTG Deluxe Mesh Trap Shell Catcher for price if you source one off eBay.
