That double ribbed shotgun looks like a mechanical solution to a shooter headspace problem! Check back in a couple weeks and he will have some other stupid contraption trying to solve his shooting problems without having to get instruction and practice. There is a gunsmith somewhere nearby laughing his butt off on his way to the bank - just knowing this dude will be back shortly with more money. Looks like the gun already has an adjustable comb screwed up to max elevation so he can get his cheek on something to position his eye behind the rib. Probably has a automobile's power seat mechanism built into the buttplate with 6 different axis of adjustments to tinker with too. Bet the gun swings like the proverbial pig on a snowshovel too.
