Question for S&W owners.
I have a question for the S&W MP 15 crowd. The barrel is marked 5.56 but i know that they are not always up to spec. How many of you have been shooting 5.56 through your S&W? Have there been any problems with the barrels? I have a good amount of 5.56 in the house and would like to get out soon and shoot it off. I know there are a good number of Smith owners out there, so I expect that the answers will vary, but lets hear them...

Should be GTG.
I have several AR's (including Colts, Noveskes, Knights, a POF, and a LWRC) and two of them are S&W MP 15's (an ORC and a FT). Both are chambered 5.56 and I shoot them on a regular basis at the range and they have both been through carbine courses without a hiccup. They tend to be my 'go to' and 'beater' rifles and will probably be my SHTF rifles should the need arise.

Not necessarily GTG. Barrels are only MPI batch tested. Only HPT batch tested as well. 1/9 twist also. If it starts popping primers, may need to ream chamber.

Just got an M&P15X a week ago, so I am no expert here. But I have put 350+ rounds through it, with half of that being 5.56. I have had no trouble at all. Honestly, I can't imagine being any happier.

I've had my M&P 15A for about a year - put nothing but 5.56 through it with absolutley zero problems
-
Same experience; many thousands through my M&P, along with tens of thousands through many M&P-15's my job issued, all in 5.56, and no problems.
-
No problem at all with many different S&W MP15's and Federal XM193.

purchased my M&P15 last February and have shot over 1k rounds of WWB 55 grain 5.56 with no problems (no ftf, no jams, nothing). Also shot about 500 rounds of various 55 grain .223's again with no problems so far FWIW, YMMV

I've shot a 1,000 rds of PP M193 through mine with nary a problem.

Here here.
Lots of 193 without a problem. My barrel is also marked 1/7, and reliably handles 62-75 grain ammo.
