There is also the posibility of a modified turret to handle recoil better but that would be a house rule at best.
Rough thoughts are based on the idea that in a turret or mounted point you could allow some movement back and forth to allow the blowback to be disipated more easily. Nothing to crazy but you could add a mod in for a couple of points of recoil reduction in.
3rd edition had "Gunnery Recoil Adjusters".
You could houserule those back in.
4th edition just likes to streamline everything.
