Two LAC/5s are lighter than a standard AC/10, so two LAC/10s being lighter than an AC/20 is fine IMO. I'd leave the weight as is.
Come to think of it. I remember hearing that the US tried developing a rapid fire 120mm for the Abrams. It definitely fired fast enough, but the repeated powerful recoil caused the gun to tear the turret off its mount.
Maybe if a RAC/10 (or RAC/20) fires more than 2 Shots, besides the improved chance to Jam, it also forces a PSR akin to the HGR, with a modifier based on the increased chances to jam.
I think the most straighforward way to model the effect you describe is to forbid heavy RACs from being mounted in arms or turrets, so the recoil effect cannot tear off said limb or turret.
AC/10 ammo count: 10 shots/bursts per ton. (that is ten shots in single mode, how those shots happen is fluff.) 100 KG of ammunition with each pull of the trigger in single mode.
UAC/10 ammo count: 10 shots/ton x2 so 200 KG per burst of two shots, meaning aside from failures, you can fire it five times before you run out.
RAC/10; 10 shots/ton, but look at your multiplier for a moment. Double-tap 5 times, like an Ultra, double that, that's two and a half times. (burst of 4), or go all six followed by either four shots, or two double taps.
all this barring jamming.
NOw, back in the day, when we were playing with House Rule designs...I came up with something even MORE absurd.
Behold, te Metalstorm AC/10. One ton of ammo expended in a single trigger pull at max rate, PSR Plus two to remain standing if you're in a Quad 'mech over 80 tons. Anything smaller, and it's straight to falling damage *{PSR for half).
May not be mounted on turrets, weapon ONLY comes with one ton of ammo, reloadig procedure involves dismounting the gun and mounting a loaded one.
it gets worse; you take a pilot hit when you fire it. No save, no piloting check, you take the hit.
Vehicle mounts require a PSR to avoid Crew Stunned result from firing at full max rate.
You can blame John Ringo for this.
On a more modest scale, I think you could model MetalStorm weapons as rocket launchers, except as ballistic instead of missile weapons.
