Solid as they come - FAB Defense NFR M16 Aluminum Picatinny Quad Rail Handguard

This is a rock-solid carbine handguard. The fit and finish is very nice as well. Once I got this thing mounted on my rifle it wasn't going anywhere. I'd put this up there with any of the big names as far as rigidity and ruggedness goes and it's surprising that this isn't more popular. I suppose it's due to the price, either super budget like UTG or Daniel Defense, nowhere in between. But in between is exactly where this rail falls. So if you're looking for the performance of the big expensive names and want to save a few bucks (like $100 or more) than this is a great option and I highly recommend!
