I recently purchased my first AR-15 M&P Sport II in June 2020. All was good the first two times me and my son went out. (about 300 rounds) loved it, but I noticed the distance the shells were ejecting was getting shorter and shorter. I thought this might be part of a break in period. The third time, (in July), the shells were not always ejecting and jamming up the rifle. It would shoot one, sometimes two, and then jam up. I know a little about the way things work. I also watched about 100 YouTube videos. I concluded it was a gas leak. I checked the gas block, port, tube, key, and Bolt Carrier Group. I was using quality ammo. All seemed good. I contacted S&W to arrange a return. Rule 1. Weapon must be put back to stock, Rule 2. Shipped in an unmarked box. (My box has Smith & Wesson in huge letters), Rule 3. FEDX only (and many locations do not ship weapons so you have to do your own research to find one). I didn't want to give up. Then I saw a video on checking the BCG. Checking the gas key screws with reverse torque. BINGO!! The head of one of the socket head cap screws had broken off, causing the gas leak. The staking had stopped the head from falling out. I think this had to have happened during the assembly, probably from the staking process, because operating the weapon should not cause too much stress on the screws. . I contacted S&W, they still wanted the whole gun!.
I ended up buying a new bolt carrier. $125. S&W would of had my weapon 6-8 weeks. they could not tell me where they get their BCG's . I bought one from Lewis Machine Tool. (a military supplier) (LMT), because I read they sometimes make them for S&W. I know there are 100's out there who make them, I wanted stock.
I just wanted to throw this out there. I try to inform people having similar problems. I have been a loyal customer to S&W. I know stuff happens, but I should have been able to return just the bolt carrier group
