I just got my Seekins 12" MCSR rail and it looks amazing. However, the aluminum barrel nut has a protruding burr on the face that will meet with barrel extension, covering about 1/3 of the circumference. Since the barrel nut is aluminum, will this compress and not be an issue, or will this cause the nut and/or barrel to not sit square and be a problem? Pic isn't great, but you can get a sense of what I'm talking about in the pic from about the 9:00 to 12:00 position on the inside radius. Thanks guys!
