So like the title says, miniguns and gasvents. Yes or no.
The rules don't say anything explicitly about it either way but logic makes me question it. However, if they don't get gasventing, shouldn't they instead have something like the high velocity guns and get some sort of inherent recoil comp?

I'd say yes to minguns and gas vents, but there's a pretty long discussion about it almost 10 years ago over here.

Yes but the same Gasvent on ALL of the Barrels.
than you get the compensation for ONE

HougH!

I waded through that post, and ignoring the comments about creating a magical recoil comp spell, the general consensus was....no consensus. Ranges from sure, go for it to yes, but pay for it 6 times to nope, can't do it.

If I had to pick from those choices I lean towards either no or else buy it for each barrel. I'd rather just say miniguns get some inherent recoil though, say 3 points, like the high velocity weapons.

And what's wrong with having a singular gas vent as an accessory and barrel extension, like this? Same principle on revolvers where you've got a minuscule gap between cylinder and barrel, or barrel & vent in this example on a minigun.

(Relatively) short answer:

It could work in principle. But you'd have to have two very difficult problems solved.

The first very difficult problem is that your barrels would have to line up perfectly (to within a thousandth of an inch or better) with the gas venting system every single time, or your gas venting system would not last very long nor work very well. You could certainly invent a locking structure that ensures that, perhaps by locking the venting extension to the barrel every time, but you would run into a problem then that the whole system becomes slower and more complex. Theoretically possible. Practically dubious.

The next problem is that the whole reason for a minigun in the first place is to mitigate the effects of sustained fire on the barrels themselves. Try shooting fifty rounds in fairly rapid succession from a revolver with an unshrouded barrel, then feel the barrel. Quite warm, right? Now imagine what would happen to the venting system.

It would make more sense to cut vents into the front of each barrel in the minigun, as you might do on a revolver.

..why Gas-venting? add Gyro Stabilisation system,Personalized Grip, Underbarrel weight..more RC would come if STR 6 (and more) to RC rule is used..(military Grade Armor w/STR upgrade)..

In other words, you have all the disadvantages of a gatling cannon (weight, n of every component) combined with the principal disadvantage of a revolver cannon (all the strain and wear on one barrel)
