If anybody has a BCM KMR13, could you please tell me the actual length to the end of the rail on both the longer and shorter sides?
I'm trying to figure out which barrel to order and it's coming down to the fact that one company's is 11.5" and the other is 12.5", but one comes with a gas block and tube and the other doesn't so I'd need to order those as well, and blah blah blah.
Thanks in advance.
