Design flaw permeates nostrils with gasses much more than original rail. - Manticore Arms X95 Overwatch Full Length Top Rail

I installed this and originally felt it was a nice upgrade, bringing the optics and magnifier to a more suitable position for both cheek weld and a more heads up position for improved target acquisition....Unfortunately due to the cut out and bottom cut out which the original rail does not have, the blowback gases burns your nostrils when firing.....the action is essentially wide open after installation. I would surmise that it also means dirt and debris can enter the system more easily creating potential malfunctions when operating in harsh environments and conditions. So unfortunately no, I cannot recommend this product.
