The magazine in the late prototypes is basically a fixed box magazine loaded using an en block clip.  The magazine spring and follower are fixed to the gun.  The loading process is involved; there is a lever with a handle under the magazine box, connected to the follower by a chain.  Pulling back on the lever tensions the chain, which pulls the follower down and compresses the spring.  At this point, the side door is opened and an en block clip is inserted.  After the door is closed, the lever goes forward and the chain tension is released, allowing the spring to expand and push the follower up into the en block clip through a protective tape seal.  At this point, it works like any other box mag, with spring pressure pushing the follower up and the follower pushing the rounds up into the receiver feedway.  It's not a mechanism conducive to rapid reloads but it might save a bit of weight and cost by not having a spring in every clip.

I can see a problem..  The mag spring is in the gun.  If it's defective - or becomes defective,  The gun becomes useless. 

I can't find any info on how the. LSATgun supposedly had weapon powered clips.  Only wiki briefly mentions it.

At the risk of being flippant, that sounds like what a belt feed is.

And machine gun stoppages aren't exactly easily dealt with.

Would depend on the gun, I would think. Given that the basic load for a machine gun is over twice that for a rifle, it can’t be that much of a risk in the first place or unmanageable should it occur.

The LSAT linkless feed magazine had a feed sprocket which was driven by the operating rod / bolt reciprocation and rotated to move rounds through the feed path. It’s shown in the Textron patents for the carbine as the LMG was always to use the polymer loop belt.
