Just received my BG and before I commit to drilling and tapping I wanted to test fit it with the bolt. I set the BG in place and inserted the bolt carrier but it would not close all the way. cause the bolt was hitting the BG you can see in the pic where it marks on the guide. I have a flat trunion so it's not just a case of moving the guide left or right.
Should the problem go away after I bolt it down? Anyone have any suggestions as to what may be causing this. I will be emailing CSS.
