Surplus is cancelled by the raid gloves though about 110 drops will still give you the extra ammo per drop as intended . Running around archons forge with a sword and only the raid glove will give you infinite ammo . So the other poster saying a taikonaut and surplus weapon were equipped really means nothing . It looks like your post is getting a lot of misinformation about how surplus works especially its interactions with the raid gauntlets . As for your question about the raid gauntlets and taikonaut originally , they should stack . But the taikonaut itself was not very effective at giving extra heavy from my experiences in the first place , which is why I always used ruin wings which does stack with surplus
