So, one of my characters is considering modding an assault rifle (probably the AK97) in a manner similar to the Infiltrator from Fallout 3 (For those who don't know, it's an assault rifle with a scope and silencer, but no stock). Now, to me, scope+silencer+stock removal doesn't make much sense....but scope accessory+folding stock+suppressor accessory does. Now, I'm wondering:
How would stock replacement work with the modification rules?
How can I maximize concealability? (Chameleon Coating+Ceramic Components?)
How could this concept go wrong? For some reason, the GM in me can't find a suitable countermeasure unless something goes wrong to begin with (ie his cyberware sets off an MAD and he gets patted down)

Any non-visual perception test would likely be a problem. A chemsniffer for your bullets/gunpowder might be an issue as well.

The only thing I know of for making big guns smaller in RAW is Barrel Reduction, which isn't a terrible choice. You're right, there is no stock removal; AR and up all have stocks (AFAIK), and the implication is that they need them to work.

D'oh! I should've remembered chemsniffers.... >.<

Dropping a sling mod on a gun lowers it's Perceptibility by 2 or by 1 depending on whether it is secured or in a ready state.

To me, that implies that a stock was removed and the strap is being used instead to keep the gun steadied.

A guard using a UW band radar will see it right away, even under that long coat.

That's not what it implies to me, Saint Sithney. But your table is your table.

That depends on whether its a stock Accessory or stock Modification. If its an accessory, you can just take it off. If its a modification, you can remove it, but you don't get any slots back - however, i *would* allow it to be modified from a stock to a folding stock by paying the difference in slots, nuyen, and threshold.

Chameleon coating can do concealability, and fits in with your stealthsuit. a Sling modification can do concealability as well, as can Barrel reduction. Easy Breakdown can be used to make the rifle not look like a rifle at all when sneaking it through scanners. Ceramic/Plasteel components can help get it through MAD scanners.
Getting a scope is as easy as attaching an Imaging Scope accessory from the main book.
Silencers are as easy as slapping an accessory on it. A modification silencer works better, but is modslot intensive.
I would probably try to use an SMG for this instead, just due to the lower concealability to start with.

I'm just saying that there *is* no stock mod or accessory for longarms. There are maybe a couple shotguns that having folding stocks (or are actually just heavy pistols), but the 'right' way to do this is (as above) to use an SMG. Isn't there an AK97 Carbine?

As a house rule, I'd be fine with a +Conceal, -RC folding stock replacement for longarms. I'd say +2 Conceal, -1 RC, because you're basically making is SMG-sized and the stock seems to give 1 'factored out' RC.
