Is it possible to put "standard" handguards on an unconverted front end? I just looked on Ironwood Design's page [happy they're still around] and they show an S12 with AK style furniture on it and the gas tube sticks way out in front.
as if you can then that pretty much removes my only reservation.
With regard to current KS-12 and Saiga IZ-109 shotguns, some level of customization is necessary to install AK furniture. Dinzag (an S12 forum vendor) manufactures and sells this set up which will work with the KS-12 or Saiga IZ-109: http://www.dinzagarm...a_12/aks12.html
