Alright, so I recently bought, refinished, and fitted some Romanian RPK furniture for my KS12, but I've run into a problem and have been a bit to lazy to address it, that is of course: how the hell do I get this mounted? I'm unsure what front handguard retainers to buy, and how they would exactly fit on with the big gas block in the way. On top of that, how would I get the top handguard mounted? Thanks.
