Garbage, but you get what you pay for - Firefield Edge Series Keymod Picatinny Rail Adapter Segment

Well i rolled the dice and lost. This is a very cheap and out of spec part. The anodized finish is deep blue and relatively glossy so it doesnt match any rifle finish. The KeyMod screws/cams dont fit flush, the screw head sits crooked off at an angle. This makes 2 of the slots virtually unusable. The dimensions are also off, seems like its too big, as several of my accessories (name brands like Strike Industries, Olight, Sightmark, Trijicon, Streamlight, magpul, etc.) Dont fit. So, hate to say it, but dont waste your $6, just spend the $15-20 and get something decent.
