So I picked up an M & P 15 Sport a few weeks ago. I have done mostly hundred yard shooting with it 3 different times since then.

I mounted a Nikon Prostaff 2-7 x 32 on top of a 1 in riser, and have consistently shot 1 1/4 - 2 inch groups at 100 yds. This is done with PMC ammo from cheaperthandirt.com and resting it off an old milsurp medium ruck from somewhere in Europe I can't remember while shooting prone from a blanket.

I am new to the AR platform, always did commie guns before. I love this rifle, it's really fantastic and nice to get this kind of accuracy out of the box. I'm sure that part of the bigger groups are me, and also the M & P has a horrible trigger, and a lousy pistol grip, both of which I will do something about soon. My WASR with the Tapco G2 trigger was better than this as far as trigger affecting accuracy.

Want to also give a shout out to your high roaders for your scope advice a few weeks ago. Much appreciated. This Nikon can be shot both eyes open on the 2x and is very clear and usable. I'm a fan.

The native stock it comes with is nice but has some wobble. I'm looking to put on a replacement stock. Since I am primarily planning on using it with this scope, I am wondering why do many of the "sniper" stocks for ARs have cheek risers and adjustable cheek pieces? I am using weaver rings on top of this 1 in riser, and yet I have to get my face right on the stock to make it work. So I would wonder why would you want a stock for an AR that raises your cheek weld? I had to go through two risers to get one high enough to get proper eye relief. Seems backwards to me.

I'm looking at the Magpul MOE stock and the MFT Battlelink Utility. Thoughts?
 
Some scopes are mounted on top of carry handles. Some scopes have bigger objective lenses and need to be mounted higher.

If you want a stock without wobble without haveing to change out the receiver extension...look at the Magpul ACS, CTR and STR. They all have a friction lock which absolutely cuts wobble. I have and ACS and love it. With the friction lock on it is perfectly stable.

Grip: The Magpul MIAD grip will give you options for a larger grip. $30

Stocks: The Magpul CTR $90 and STR $?? are light weight and have friction locks that will take out he wobble. The Magpul PRS is a very nice fully adjustable "sniper" type stock. $250.

I like Nikon as well. Good choice.

Trigger: ALG Defense is made by the same people that own geisele. They are milspec, but they say are better quality. $60ish. I like single stage triggers. I like my Timney 3 lb, but it is $200. The Geisele S3G is said to be very good at $240.

Ammo: ATM I like AE223, cheap and fairly accurate for cheap stuff. I shoot it in 3 gun out to 300 yards on 12 plates with ease. Hornady Steel Match is great stuff for the price. It is steel cased, but it is as good as you can find for that price. PMC is ok stuff. I have good luck with it. I do not like Tula or brown bear. In my experience i have to many key holes. Wolf 55gr has been ok in my 1:9 twist ARs, but not in my 1:8.
 
OK, from what I gather, you are asking about two things. The pistol grip and the stock and your primary concern is the use of these two components with a magnified optic.

My first question would be what is your preferred shooting position? Do you normally shoot standing up? With a sling? Prone? Off of a bipod?

I'm asking because there are many, MANY options out there. Pistol grips vary in thickness, how high they allow your grip and by grip angle. For me, the stock grip, like the one that your rifle came with, works just fine for the purposes for which the AR was intended. Use as a battle rifle.

The best way to figure out what will be more comfortable for you would be to get to a place that will allow you to compare several models side by side. If you can't do that, then you might just be better off getting a grip that has interchangeable inserts to vary the grip angle and thickness of the grip.

As for the stock, don't let the wobble bother you. If you just want a new stock, then go for one that makes you happy. I just wouldn't go buying a "sniper" stock to fit the rig that you put together for that little 7X scope that you have. I'd suggest getting a proper scope mount for your scope that is going to put the scope at the proper height. I believe the spec is something around 1.5" from the top of the rail to the centerline of the scope.

I've had 4Xs, 10Xs and 22Xs on top of ARs and never needed to do anything fancy with the stock to get a proper cheekweld. If you are on a tight budget, look into a PEPR mount. That will put the scope where it needs to be. If you have more money, check out the Bobro, LaRues and American Defense mounts.

Personally, I prefer the Magpul UBR. It has the feel of a full size stock, but can be compact when you need it to be.

If you decide to go with a stock that will be a direct replacement for the one that you have, and your concern is getting rid of the wobble, I'd suggest that you try to check for fit before you buy.

I don't know if the M&P Sport comes with a milspec sized or commercial spec buffer tube, but with commercial spec tubes, getting a stock with a wobble free fit can sometimes be a bit of a challenge. It can be hit and miss with milspec tubes too. Even the CTR with the little locking lever can leave you with a wobbly fit; so if you can, check the fit before you lay out the money.

Mil spec tube.
 
Yes it is a mil-spec tube. I'm getting married in Dec, so I'm trying to conserve money where possible. I was hoping to keep the cost on the stock at or below 90. I have an MOE handguard I installed yesterday from Magpul, and I will say it's an improvement over the factory one. I'm 6' 6'' and have big hands and like to have a thick grip with pistols and rifles.

One of the things I liked about the MFT Battlink Utility Stock

http://www.cheaperthandirt.com/product/2-MFTBUSMIL

Is that it is very sturdy by all accounts, has nice storage, and can be had for the mid 80s if you know where to look. My cheek weld on my existing stock is fine, I don't need an adjustable cheek piece, and i'm certainly not going to spend 250 on a "sniper stock" who's main feature is the ability to raise my cheek weld to where I can't see through my scope lol. It's just the wobble I don't like, and the MFT also offers some storage and a wider cheek weld than many other stocks without it being higher. But the MOE also seems like my handguard, just a step up from factory but nicer and a little tighter. so yeah, if I can get a decent one from Magpul for in that price range...
 
I've never used the MFT, so I can't comment. Like I said, though, if the wobble is what is prompting this search for a stock, try to check for fit before you buy.
 
I have a Magpul CTR on one of mine, and it has no wobble whatsoever with the friction lock engaged. Another advantage is that it is very light weight.
 
I can tell you that the Magpul PRS is most likely a waste of money, in regards to the cheek adjustments. Plenty of less expensive stocks that will give you a good cheekweld without any adjustable parts.
 
If budget is an issue, I will say that the Magpul MOE stock is pretty much the same thing as the CTR except without the friction lock and the QD sling socket, and it is much cheaper. My buddy has one, and it also has no wobble. It still has a couple slots you can loop a web sling through... it just doesn't have the socket for the fancy push-button QD swivels.
 
I was shooting my M&P 15 Sport at my local range today, at 200yds and 100yds. I was surprised at how good it was shooting at 200yds with a Nikon 3x9-40 scope. I was shooting at about 3 MOA and was using Privi brass 5.56, which I bought for $6.99 a box of 20 which I thought was pretty fair. I will be shooting it again soon, maybe tomorrow and it is a lot of fun shooting this AR. I highly recommend this to anyone, even advanced AR owners as it is just a great rifle. I put a quad rail and Magpul CTR stock on it but it comes out of the box a awesome AR-15. Does anyone else run Privi through theirs?

I have, wasn't super impressed other than it wasn't expensive. Mine liked Barnes Vor tx ($$$$$) and Black hills match. Better than MOA on most trips.
 
On the cheap? Take off stock from receiver extension. Apply layer of duct tape on the top. Re-install stock. Should clean up most of that slop. Several companies make a cheek riser for the standard CAR type buttstock if you search a bit.
