I love the BCM KMR and will be purchasing one for my new upcoming build. That said I was thinking you should produce one without a continuos top rail similar to Midwest Industries and SLR. It would save on a bit of weight, making an already incredibly light rail even lighter, and slightly more comfortable for those whose hand goes over the top rail. You could even put key mod sections where the rail used to be for added versatility. Just my 2 cents. Keep up the good work.
I think this with short sections, maybe 2", of rail at 3, 6 & 9 o’clock on the end would be cool too.
