About 4 months ago, I ordered a Saiga 12 Bullpup stock from Center Balanced Systems (cbrps.com). They've got a big line of Bullpup conversion stocks for several kinds of rifles as well as the Saiga 12 Shotgun.
The bullpup stock didn't require any modification to the sporting configuration, and measures above 31" in length without a muzzle attachment.
I have some Diamondhead flip up sights and a vertical foregrip/flashlight combo on order, and will post additional photos and video once I have those.
At the time I placed my CBRPS bullpup stock order, it was uncertain when or even if the Kushnapup stocks would ever ship. Further, Kushnapup didn't offer any rail system or under-barrel rail for attachment.
CBRPS didn't invoice or accept payment until the stocks were ready, which was also a plus. If you look at pictures of previous S12 stocks, you can see that he's made some slight improvements to the previous versions. All in all, I'm very happy with my purchase.
I still intend to buy another Saiga shotgun and do a proper conversion later.
