That is not entirely true. The ACS bolt disengages and has to be recocked when it stops from chopping. The issue usually happens with full auto because the gun will outshhoot the hopper. Usualy this goes away with a upgraded hopper.
You may also have this problem if your bolt is not broken in. The easiest way to do this is, stick a swab in your feed tube and fire the gun around 500 times. I know this sounds weird but the spring is too tight and it really does work.
Please read the threads, there is alot of useful information there.
