A while back I blogged about the, quite frankly, ugly bullpup kit by Centerfire Systems for the AK-47 that could be used with a Saiga-12. The Kushnapup is a much better looking system designed specifically for the Saiga-12 shotgun.
This video shows 10 slugs being fired from a Saiga fitted with the kit.
The kit does not require any permanent modification to the shotgun and can be easily installed, no gunsmith required. The current model only accepts stick magazines, but a new kit is in development and it will accept drum magazines. The kit costs $275.
