My previous post only covered the damage dealing part of the Machine Gun.
The other part would be: How important are critical hits.
A mech can carry twice as much armour as it has internal structure. That means that roughly, 2/3 of each combat you have to try to chew through armour. Only on the last 1/3 does internal structure damage or critical hits matter.
Now, the Machine Gun Crit buff is not a buff to internal structure damage. It's only a buff to internal component damage.
Most items have about 10 hit points. If you have two items in a hit location, this means that each crit has only a 50 % chance to hit a specific item.
The Machine Gun delivers its damage in many small damage ticks. That means the damage will spread a lot across the two locations, basically meaning that the MG needs to deal almost 20 damage to kill the first, but the second will follow almost immediately after.
Now look at a weapon like the PPC, the AC/10, the AC/20 or the Gauss Rifle. A single critical hit will destroy almost any component. So on average, weapons like these will take about half the time the Machine Gun needs to destroy the first component, and the same time to destroy both components, assuming weapon configurations that deal equal damage to internal components.
The good news for the Machine Gun - you need not even 1 to beat the DPS of a PPC against internal components.
The bad news for it is -that this means that it beats a heavier weapon in 1/3 of the combat situations on a minor aspect of that combat situation - the ability to crit weapons.
A single PPC crit will not just take out a hit location. It will also damage the internal structure for 10 damage. Even the heaviest mechs have no more than 60 points on the best protected location. The Machine Gun only helps you to take out some components at one location, it doesn't help you out destroying the entire hit location, which will
also take out all items in that location, and can also take out the entire mech (center torso, head, side torso with XL Engine), or a second hit location (Side Torso), or severely cripple a mech's maneuerability (Leg).
As a consequence, the crit-seeking buff is not entirely irrelevant, but so minor in practical applications that it doesn't have a chance of making the Machine Gun viable. And it wouldn't help buffing this aspect even further.

you fudged a number on the dps of the mg. it's 0.4 and not 4
I, errr.. was just trying to show how easy it would be to buff the Machine Gun. Erm.
Oh, look a pink flying Elephant.
