I purchased this and the matching Seekins lower for a PDW build. As of this writing, there is not a lot out there by way of reviews on this particular product. After building the complete PDW, I am very happy with it. The build quality is nothing but top notch Seekins, very light, very stealthy and everyone wants to know what it is that I have. The only concern I have is that the end of the rail sits a hair over the end of the barrel where the barrel tapers into the thread; this might pose a problem is I want to throw on my own brake and something like a Surefire Warden to mitigate concussion. Otherwise, this thing ROCKS!!!!!
