Finished bedding my MVP-LR (5.56mm). Quite the project, with 3 separate bedding operations. First, the magazine guide, second, the barreled action and third, the rear tang. I have fired groups of different loads so I will be able to tell if all the work was worth it. I will have to wait until the weather warms up a bit to test the rifle against the previous groups. I will say that the bedding does support the barreled action far better than without. The action is nice and tight.
