It will be a hydrogen fuel cell, not fusion. No one has made fusion work on a net gain yet.
On the capacitors here is a thought - you could make a replica AN-94 that would work the same as the real on. By using a capacitor you could get a really high ROF for a couple of rounds until the capacitor had discharged. Then the rest of the rounds could be fired from battery power. Then when you stopped firing it would recharge the capacitor.
For those that don't know the AN-94 is a Russian rifle that fires the first two rounds at 1800rpm, then the rest of the burst is fired at 900rpm. There is also a 2 round burst mode that fires 2 round bursts at 1800rpm
