I'm wondering if anybody knows if there would be any issues mounting a suppressor on a 16" barrel with a 15" KMR rail. I'm not sure if some of the suppressor would have to be recessed a bit inside of the rail or if it has enough room as is. Would a QD suppressor make any difference in this matter? I believe BCM's websites claims that the interior measurement of the KMR rail is 1.5 inches. Just something I've been wondering about and haven't been able to find any answers for.
