Its one of those things. Its really easy to get the gun to fire f/a. Basicaly, make the slip-sear not slip. But slowing the hammer, and increasing the feed are 2 hurdles that have never really been done easily. Look how complicated the Tippmann F/A ended up being. Forcefeed hopper AND dual hydraulic shocks to slow the hammer... and it still was unreliable.
Different system entirely of course but the idea of using a secondary sear that retards the action somewhat to slow cycling could be done. Ive simply never thought much on it.
