I got this Mini 14 in a trade. I put a scope on it and can sight in a vortex scope, which has around 80 moa of adjustment range on the windage, but have adjust it to within 5 moa of bottom left windage. To the eye something doesn't look right, so I lined up a straight edge along the left side and right side of the scope mounts. (see photos) I think maybe the barrel isn't screwed in right, the hole where the barrel screws in isn't perpendicular to the front face of the receiver, or the scope mounts are misplaced. I don't think this is a gas block problem, as the problem persists with the stock and other parts removed. The gas block is only touching the barrel, but the straight edge still indicates barrel or sight misalignment. I suppose I have to send this back to Ruger.
