Thats cool but it seams like the brass would build up and jam the action from the bottomThe only AR-15 I know of which effectively has a built in brass catcher is an AR-15 lower with an AR-57 upper in 5.7x28 FN. With this setup the modified 30 round magazine in the AR-15 lower servers as the brass catcher and will hold all 50 shots of the FN brass. The brass catcher releases like a normal mag and dumps easily. The mod is easy, just remove the spring and follower and cut the magazine off flush with the top of the lower receiver, a single straight cut. The 5.7x28 isn't an especially "long range" cartridge but it's good for varmints to a few hundred yards. This isn't mine but I have a pistol version which works the same way.
The 5.7x28 brass is about the size of 22 Mag brass. The 30 round lower mag will hold 50 cases since it has no spring or follower. A lot of room in there. Just dump the brass catcher each time you change the 50 round FN mag. It won't hold 100. It will jam if you try to shoot the rifle upside down.Thats cool but it seams like the brass would build up and jam the action from the bottom
