Hi Guys,
So I started buying parts for my M&P 10 to upgrade it to a free float barrel. I started to dissemble my M&P 10 gas block and hand guard. When I got to the factory barrel nut, I thought I would stop here since I did not have the tools yet to wrench off the barrel nut. I thought I would try to twist the barrel nut off with my hands as a joke to see if I can do it, and to my surprise, it came off without resistance!!!
(Not cool) Now this is factory new and I have only shot maybe 150 rounds though it. Is this normal?
