Ergo ladder rail cover. great option - ERGO 18 Slot Low-Pro Ladder Rail Cover

Using this product on a BCM QRF rail. The three sections serve as a nice package to cover the 3, 6 and 9 o’clock rails. Product is not bulky or heavy but feels substantial, secure and durable. Ordering more to try out on some top rails of various MLOk rails for a bit of added comfort. At least for the BCM, and I would imagine for several other quad rails out there, these are very worthwhile for taking away some of the “sharp edges”, for lack of a better term.
