DIY, IPSC, rifle Freefloat for Norinco 56S 2014-07-30 Hount Leave a comment Why not? That’s the answer to your obvious question: Why? Yes, it is an airsoft stock held in place by some aluminium bar and few screws. I borrowed the whole idea from a fellow hobbyist. Thank you! Not 100% happy with the outcome but had to cope with the tools I had in hand. All of this was made in balcony of urban apartment. I also made thinner front sight from M4 bolt with electric drill and file. Old thick sight next to new as comparison.
