I'm not absolutely certain but you may have a kinda rare Para collector wise. Is it import stamped on the left or right side? Most wood stocked KSI rifles have the bayo lug & rod guides neutered, leaving only the FSB and the stock notched for the "no-where rail". Hard to find without the rail and I've never seen a KSI Para with a bayo. The Para mod would have likely been done at the factory for the entire FSB to fit all the way to the gas block, although talented Bubba may have wanted a bayo and swapped it out but I think not. Do the numbers match even the wood? PAX
