[The Wyrm Ouroboros]

There is more to playing than the rules.  A silencer, by its nature, sticks out from the barrel; the bayonet, by its nature, does as well.  You would effectively have a two-inch knife on the end of your weapon which, if you use it, you run a chance of fouling up / damaging the silencer you added on.

Hence my "Maybe in visualizing it..."

Though if the bayonet is attached on top or below, the issue becomes less "Using bayonet will ruin the silencer" and more "The silencer is in the way of the bayonet."
May very well be the same result, but hey.

Longer bayonet. Stick a Long sword into your rifle and then use the barrel and the stock like you'd use with a traditional two-handed sword. Then take the negative quality for distinctive style.

[Lucean]

And suffer a loss in Accuracy for an even worse ability to utilize it not only in melee but also as a ranged weapon because of the increased weight and worse concealability (which you mentioned).
Not a good idea

[Leevizer]

But it might also count as an added weight for terms of recoil compensation on full auto!

And speaking of conceability, you'd just need to pass it off in some amazing way. "Uh, I'm uh... This is Cosplay?"

Speaking of which, if I EVER make a physical adept, I'll give him performance and stick him with this http://www.guitaraficionado.com/wp-content/uploads/2012/10/axe.jpg

Which is why I would think an integral silencer would be fine with a bayonet... still, I can't find any legit examples, real world or no.  This is one of those things where I think bayonets should take the barrel slot, while foregrip belongs as an underbarrel accessory.  Also, why the foregrip specifically can't be used on pistols is beyond me.  There's plenty of real examples of this.  The CZ 75 and Beretta 93R being two.

I see you've heard of the Lee Enfield!

Why do I think this would sound terrible, and only once.

In regards to the Lee Enflield, beautiful rifle. Mark 3* in the photo?

Quite the bayonet they had. If you're up for a little bit of history, look at the charge of the 4th Light Horse at Beersheba, they used their bayonets as swords as they fought on horse back. An action I would challenged saved the Palestinian campaign, considering the need for water, the wells of Beersheba.

Also, if you're after a really long bayonet, I believe the Baker Rifle, that was called, if I remember the accounts of Rifleman Harris, a sword bayonet. Make of that what you will.

If  INF the US military does not have the bayonet mount anymore why would you?

[JimmyCrisis]

If  INF the US military does not have the bayonet mount anymore why would you?

Why would civilian criminals care what some military strategic supply bureaucrat decides is good for the rank-and-file grunt?  It's apples and oranges.  For one, shadowrunners don't need to march through the jungle or the desert with 100 pounds of crap on their back (usually), and they also don't get to count on serious back-up when they run into a firefight.  Plus, who gets killed with a bayonet anymore?  Total style points.

They still have bayonet mounts and issued bayonets, just so you know.  They even give you some training on it.

[The other Bandit]

I am sure in the 2070´s some company will have made a bayonet rail adapter so you do not need a bayonet lug on your rifle (hell there are fricking chainsaws attachable!!!).

So  silencers and bayonets might work... but better be sure to get a looong bayonet!

Or you could use an overlong freefloating frontrail set-up that covers the silencer almost to the tip and mount the silencer on there... hm that actually might look really badass... stupid but badass 

[The Wyrm Ouroboros]

'Stupid' automatically fails the 'badass' test.

[Xenon]

pretty sure at least the top of the four under-barrel-mounted bayonets in the picture below would work with a barrel mounted sound-suppressor (at least length wise).




One more example:






Pistol mounted bayonet?

[The Wyrm Ouroboros]

Length-wise, maybe - at least a little.  Like I said originally, you'd still be risking damage to the silencer if you want to do any real damage with the bayonet.  *shrugs*  Stupidity is its own reward.

On the other hand, I gotta admit that that pistol-bayonet is just about the most violent-cute thing I've seen in a while.  An almost realistic version of the pistol-blade things ... after all, if you have two inches of steel in you, you might forget that there's a barrel with bullets immediately behind it ...

If that was true we would live in a very boring world.

Heck, we play a game in which the terms "cyberninja", "racoon shaman", "nanotech AI" and "president Dunkelzahn" may be uttered in the same sentence without too many raised eyebrows.
That could be interpreted as pretty stupid, yet it is exitingly badass 

More on topic:

I still think the supressed bayonet could work awesomely, but only in specialised cases.
For example, can you just take your standard Sandler TMP, screw on a supressor and attach a bayonet? Propably not for reasons mentioned above.
But if a player comes to me and says his gun fu adept needs a bayonet on his silent SMG, why not?
An internaly supressed SMG like the HK227S, with the melee hardening mod should be sturdy enough to mount something sharp on the under barrel rail.

@Xenon: Big props for the picture of the trenchgun with mounted swordbayonet... THAT is how you do CQB!
