I just purchased a new S&W Magpul (new midlength) rifle. The rifle is very light without using a pencil barrel. The rifle runs everything from frangible to speer gold dot .223.

Anyways, as I was sighting it in I noticed I had to crank the Midwest Industries flip up rear sight almost all the way to the left.

I tried another sight (A.R.M.S.) and I aslso had to crank it to the left.

This seems to me like a problem with something not lining up but I am not an AR armorer. Should I be sending it back to Smith and Wesson or is this a non-issue? The front sight does not looked canted (could be off a hair though).

The other reason why it is concerning is that when I bring the rifle up the rear sight is so far over that after shouldering it I have to move my head it get it lined up, never had to do that with nany other AR I owned.

Thanks for the help.

Look at the rifle from the muzzle end (unloaded first obviously). Does the FSB appear to be canted?

[Disregarded9-side]

I feel like there was a guy on here a few months ago with an S&W M&P of some description (Sport?) that was throwing the lead off to one direction like this. After a long thread the community seemed to agree it was something about the barrel (?), he sent it in and S&W sent him a new rifle.

Think that was here.

FWIW, I've only had very positive experiences with S&W rifles.

[Mayhem like Me]

two things come to mind well 3

1) As mentioned the fsb canted

2) The front of the upper could have been out of square and the entire barrel assembly is angled.

3) Machining of the upper rail is out of spec not allowing the sight to line up correctly.


Soo I would send it back, to confirm have another shooter verify you don't have some weird optical thing going on.

Had another shooter fire the rifle and it was on with the rear sight to the left.

Something is out of whack (either FSB canted, upper out of alignment, etc etc) and should be fixed. You could get by with the sight cranked to one side but why. Smith is pretty good about their customer service and should take care of it.

Do you have an armorer in your department, if so have them check it out.

[Apetrulis01]

By armorer do you mean someone who has the certificate, or someone with the certificate and knows what they are doing.

I will just send it back to smith, they are sending me a shipping label.

I had a CMMG M4gery back in '09 that I had to max out the windage on the rear sight, (all the way to the left), and move the front sight down significantly to shift the point of impact to center mass. Turns out the FSB was canted, though it took TWO trips back to CMMG for them to rectify the problem.

As others have said, S&W CS is really good. Contact them to get it fixed. Good luck.

Best,

Reminds me of back some time ago during the ban when the front sights were all too low, it was rare to have any guns with the proper "F" marked. Everyone needed new tall front sights to go with the shorter and sometimes canted towers.

I bought an M&P OR about two years ago or so. It's FSB was canted to the left ever so slightly. You can hardly see it but the rear sight needs to be cranked over about half way or more to shoot true. I want to change to a fixed A2 sight some time so hopefully I can fix it then, but it's not a big deal.

As long as the max amount of adjustment is not reached & it zero's, there's nothing wrong with it. I have a few MBUS rears that needed to be cranked almost all the way left or right to zero. These are on BCM uppers. 1 I replaced with a troy & that almost didn't need adjustment.
