My first post and wanted to say hello, I bought my first .308 M&P 10, and I have been impressed with the fit and finish and the performance so far, how ever, after only 150-200 rounds down range, my gas block has shifted from recoil. Called the place where I purchased the rifle, and they realigned the block and put some blue loctite on the threads and we are back in business. I read through the forum and could not find any one else with this issue out of the OEM gas block, could have been a QC issue with improper torque on the mounting screws.
Just a heads up. might want too check yours out if you still have the OEM gas block installed.
Glad to be apart of the forum!!
