Good question... it was sold to me as an h2o along with the box but I dont remember if there are papers inside. Any serial numbers I can look for? It was a decent deal.1200 for h2o with extended tube, metal saddle thing for shells, surefire light and pressure pad, foregrip, and trigger (didn't install). I've seen better deals though for a similar price. Just saying he probably wasn't trying to scam me haha. If only it had a telescoping stock
