Thank you guys for all the replies. Really learning a lot about firearms and happy to be a owner of a Ruger 556. It truly is a statement of commitment to the 2nd amendment. I highly doubt that I will ever shoot out the barrel and my wife best friend husband is a quality blacksmith.In fact he’s told me he owns 2 Ruger AR 556 for hog hunting. Mine is basically SHTF weapon that won’t see to much action.
