Howdy all, newbie here, been lurking and learning for a while. Picked up a new gen2 308 from Cabela's, couldn't get the keymod pic rail to fit the hand guard. The QD sling mount fits fine. The pic rail isn't machined right on the bottom where the nuts fit. The instruction book shows how to install it, but it shows to put the nuts in backwards from how the keymod drawings I found online show. I called Ruger, they sent me a replacement rail, but it's the same as the first one. The person I talked to at Ruger said that they were not aware of any problems. I couldn't find any mention of this looking at all 35 pages of this thread. I can't be the only one that has run into this issue. Anyone out there ever see this? I milled the slots in the bottom side of the rail so the nuts would slide far enough, now it fits fine. Is this why the gen3 went to m lock?
