M&P Sport II Optic Ready Question
I purchased the M&P 15 Sport II Optic Ready a few weeks back.
Great AR!! It comes standard with Crimson Trace Red/Green Dot Sight. Sight works fine with the rifle.
My question does anyone know what type of Rail Mount that is installed? As I am new to rail mounts on AR's I am not sure if this is a Picatinny Type? Need answer as soon s possible as I have found a great price on a better red dot with flip to the side magnifier.
Any help would be appreciated!

Welcome to the forum GP. Yes, the "rail" on your new AR is the classic "picatinny" rail. Zillions of picatinny rail-mounted optics await you. Depending on what you want, they come with assorted mounts at different heights, mounts with rings for conventional scopes, mounts without rings, etc. As you research the optics they should state what they actually include or don't include in the pkg.
Which optic / red dot and magnifier are you looking at?

No, it isn't. The rail on your upper is a picatinny rail. It is not M-LOK. M-LOK is a completely different specification for attaching accessories to the handguard, designed by Magpul.
A M-Lock picatinny rail would be a small section of picatinny rail that is attached to a handguard with the M-Lok system. Basically an adapter to allow picatinny accessories to be used on a firearm with the M-Lok system.
Yes, accessories designed for picatinny rails will fit on your receiver. Picatinny is a made to a specification so that you can be confident that they will fit.

Thanks for the Welcome and information. I am familiar with Picitinny. However, S&W states that this is MLock Picitinny Style, Do I have to use an MLock adapter ect. I feel kinda stupid as I have been aroung long guns a long time, but mostly bolt action

I'm reading / looking at the Sport 2 / Optic ready Ar and I find nothing regarding M-Lok. It has their version of a basic M4 handguard (round with no slots for m-lok accessories). Don't feel stupid. You got to learn somewhere / somehow and reaching out is the best step you can take. Picatinny, is Picatinny, is Picatinny which has zero to do with M-Lok in the sense that you speak of. Do you have literature, etc that mentions M-Lok? Is this your gun? M&P(R)15 SPORT™ II Optics Ready | Smith & Wesson

Looks like that model comes with Magpul M Lok handguards and...……...they also include 2 M Lok rails to attach to the handguard if you wish. That's the best I can decipher it.
I own a bunch of these S&W guns. Converted most to piston using Osprey. I always bought the basic optic ready versions as I strip all that other junk off. Never bought one with magpul furniture included.

What a lot of people do is fail to provide the proper model when they ask questions. You stated that you had a M&P Sport II OR, which is different from a M&P Sport II OR Magpul MOE M-LOK Carbine Length Handguard. Two separate models, to separate sku... The link you provided, M&P(R)15 SPORT™ II Optics Ready | Smith & Wesson is the basic OR, and it does not mention MLOK in the features at all...
So if you are saying that you have the one with MLOK, the rail that is part of upper where the optic would mount is not M-LOK picatinny... it is just picatinny. If your documentation refers to M-LOK Picatinny rail panels, it is addressing the adapters that are made for the handguard, not the forged rail on the top of the upper.

Welcome to the forum Gunnypapa. I am sure you will find your new M&P15 Sport OR a lot of fun to shoot. We look forward to a range report.
The optic that came with your model #12939 mounted using the Picatinny rail not MLOK.
The MLOK on your rifle is in the hand guard. The long oval holes are MLOK slots. This is where MLOK accessories can be attached. You can also use the M-LOK Picatinny-Style Rail Panel in the MLOK slot to attach picatinny accessories.

The M-LOK refers to the system to attach devices to the handguard. If your optic is attached via the rail that is part of the forged upper, that is not M-LOK. That is standard picatinny.
The S&W site states that the your rifle comes with "2” M-LOK® Picatinny-Style RailPanel Included".... that refers to a piece of rail that you can attach to the handguard via the M-LOK system to use items that would typically attach to a picatinny rail. It is an adapter, M-LOK to Picatinny.
The rail your optic sits on is not M-LOK. It is longer than 2", so obviously not the rail piece stated above. It is the same picatinny rail that is on my Sport, or any other M&P 15 railed upper receiver.
So, just to be clear, you have a standard picatinny rail that is part of the forged upper receiver where you mount your optic. You also have a Magpul M-LOK carbine length handguard, where you can attach things such as lights, bipods, sling loops, or other accessories using the M-LOK system, or you can utilize the 2" adapter rail to attach accessories that are picatinny to your handguard.
Not trying to argue, just trying to let you know the difference so you know what you have.

Ok... grab a tape measure and measure the rail that is part of the forged upper. I guarantee that rail is longer than 2".
In your box, your rifle should have come with a 2" section of rail. It will have screws and cam nuts to attach it to your hand guard. You set this rail over the oblong slots on your hand guard and when you tighten the screws the cam nuts turn so that it can't come out of the slot. That is your M-LOK picatinny rail. It might be loose, or it might be attached to the hand guard already.
Here is a video... you can move to the 2 minute mark if you want to skip hearing about the guy's rifle and hand guard he chose... But it shows how to mount the rail section.

Ok, I do not understand why you keep pointing me to the Handguards. 1st of all I am very familiar with M Lock system. My handguards are MLock, they have accessories attached as we speak. I am referring to the the rail on the upper receiver where my optic sight is. Additionally the rifle comes ready to shoot out of the box. The 2" rail refers to the MLock attachment on the "Picitinny Style Rail.
y question on this thread concearns if a nother sight will work. Also the rail is made by Smith and Wesson. I have other firearms
withe picitinny rails. I tried to see if an accessory would work but the rail is too wide and it just would work, I am referring to a MantisX firearms device.
I have attached pics of my rifle for reference.

I keep referring to the hand guard because that is where the "m lok picatinny rail" is. The rail on your upper where your optic is mounted, as shown in your pics, is a picatinny rail... not MLOK anything. In the 4th post in this thread, you stated "The rail is is a MLock Picitanny Style Rail" and that is not correct.
Look at this rifle, exact same as yours except for the handguard. Note that it does not mention "M-LOK" at all. The rail on the upper is MIL-STD-1913 Picatinny. This is the same forged upper as yours, just different handguards.
M&P(R)15 Sport™ II OR 30 Rounds | Smith & Wesson
If you have a device that mounts to a Picatinny rail and the rail is too wide, one of two things is going on... Either the rail on the upper is out of spec, or the mount is out of spec.
With my Sport and mounts that I have used, I have found that for some of the mounts, I can loosen them enough to attach on to my rail. Others, I have to take the cross bolt completely out before I can get it to go over the rail. But I have been able to mount them all.

I stand corrected. That is a standard Picitinny Rail. After really looking at the optic mount I figured out what these websites are advertising incorrectly. The 2" picitinny "style rail is actually the adapter on the optic and riser, which measured exactly 2".I also retried my Mantis X system and it fits. So thanx for the help, it is appreciated brother!!

Good that you got it sorted, GunnyPapa. I have a M&P 15 Sport OR which has a Picatinny on top, and a tiny one on the gas block for additional sights. I added a new aftermarket M-Lock handguard to get more access points, so it now looks much like yours, I imagine.

You will have to let us know how that MantisX works with a rifle. I saw them a few years ago, but they didn't have a rifle app, only handgun at that time.

I will letyou all know. Been using it for a couple years. Best trainer out there!! Especially when you are just sitting around with nothing to do at home. It improved and/or sharpened skills hands down. The new app has just about every make and model out there. Whats great you can use it at the range in live fire mode.

Well, if you just have to kick the hornets nest... That adapter is pure picatinny as well, but to his main question, any device that is made to attach to a picatinny rail should work fine on the rail on his upper...

Hey pasound,
I have an '09 M&P 15T (awesome except for the proprietary barrel nut that only accepts a couple Leapers UTG handguards).
Question for you:
I've got a buddy that just picked up a M&P 15 Sport OR with the railed front gas block and I want to recommend he adds an extended rail.
Of course this gas block is not low-profile, so when you installed your MLOK, did you have to remove the railed gas block or do you have a hand guard that clears it?
Thanks!

SaltyMountainMan83, my M-Lok handguard is the Magpul MAG424, the carbine length, which fits the M&P 15 Sport OR without any problems. It clears the gas block.

Question for you:
I've got a buddy that just picked up a M&P 15 Sport OR with the railed front gas block and I want to recommend he adds an extended rail.
Of course this gas block is not low-profile, so when you installed your MLOK, did you have to remove the railed gas block or do you have a hand guard that clears it?
Thanks!

If you are talking a free float extended hand rail, chances are the rail will not clear the OR factory gas block. Per @pasound's post above, he is using the Magpul drop in carbine length rail and is not dealing with the gas block since it's a drop in rail. If your buddy wants a longer handguard that is free floated and slips over the gas block, he will have to swap to a low profile gas block.
