OMG, as fate would have it, me and my buddy had his new 12 lrp out for the second time yesterday ,,,, he noticed this very thing, barrell is way off center to the barrel channel,,,,,we tried repeatedly to hold the barrel on center and tighten screws,,it did not work,,, angle shoulder on screws and angled insert in stock return to the same center everytime , but worse , the gun prints all over the place ,,,,so back to the drawing board
