the SABS have inner componets that are derivated from the SPAS-15

yeah

there considering making a bullpup version of the AA-12

See below.

well yeah there are lots of bullpup shotguns out there
i have a bullpup conversion on my saiga-12

but the AA-12 is not just any old shotgun it has practically no recoil, is fully automatic and holds 32 12 gauge rounds

Kel-tec is the latest version of the bullpup SG but the only one I know of with the twin magazine tubes.

I know of the AA-12 when Soldier of Fortune first wrote it up a number of years ago and it was impressive then.

well i know keltec very well and there quite famous for producing flops
the keltec SKG is no exception ... for one its a pump action 12 gauge with no internal recoil dampening, its highly prone to jamming and can only hold 14 rounds total and is a real pain in the ass to reload
not to mention all the parts are milled and it has very low tolerances so dropping an eyelash in it would make the weapon cease up :P
similar to the M16

True that.

the HK CAWS is one of my personal favs when it comes to bullpup but there rare and expensive ... to expensive for me to buy one but there robust and almost all that have been produced (given in insanly small numbers) are still operational

HK has always had some top notch stuff out there.

yah but make it bullpup and you lose that recoil control shock system, unless they switch the pistol grip and Mag holder around, but then you run into comfort troubles. Either way, I find it a bit unnecessary to have a bullpup shotgun anyways, sure you might have better grouping because of the longer barrel but shotguns are meant for stopping power, not long range shooting, even with a 12 gauge, you loose that stopping power after a few hundred feet... won't deny it still looks kick arse XP

Kel-Tec makes a bullpup shotgun with twin tube mags that holds 14-16 rounds total.

i know the KSG it's one of my favourite shotguns
it have a nice design and great performances
