Buy some sandpaper & look at it for a minute before you judge it - Sniper 2 Piece Drop In Quad Rail Handguards

Bought this with high hopes, initially thought it would work, then I thought it wouldn't, then I went on to YouTube and looked up the UTG Leapers version of this quad rail (this one is essentially a copy of that, anyway, if it doesn't fit, it's because the rail extension that goes over the Delta ring might be a millimeter too long, no big deal, here's what you do. Get some hundred sandpaper, a flat surface like your kitchen countertop, or a really flat workbench, hold the quad rail top steady and perfectly vertical, sand down that rail extension paying attention and being very careful to keep it even and level, true to the sanding surface, you want to make that sanding line as straight as the factory cut, take off a little bit at a time, keep refitting it, and then all of a sudden it'll fit perfectly and you will be ready to go. The people on here that don't think it will fit need to get used to gunsmith things, sometimes with a gun you need your armorers tool or some files or some sandpaper, you don't want to be sanding on the gun, but sanding on an accessory like this at its cost is no big deal, it saved me a ton of money and it took me about 10 minutes of sanding. Totally worth it. Looks awesome I'll try to post a picture
