I been shooting my new MP15 MOE with a Barska scope but I am just not comfortable with my cheek placement. I am used to shooting a wood stock with a nice raised cheek piece. I been told to place my cheek on the buffer tube with my nose almost touching the charging handle. That looks like a bloody nose in the making on a large caliber gun. The fit feels better resting on the stock but unless the stock is set petty short the scope has to be mounted back over the charging handle. I also don't like the loose fit between the buffer tube and the stock it is to easy to rock the the gun left or right with the stock set firmly into the shoulder of rear rest. I know I can keep playing around to find what works but would rather fit it properly and learn to shoot it that way.

My new Vortex Viper scope will be here tomorrow so I will have to decide how to set it up. Don

Nose to charging handle is the method used to teach new soldiers to get a consistent cheek weld when using the iron sights. However, you should not have your cheek on the buffer tube, it should be on the stock.

When using a scope, I would set the stock length to where I am comfortable and then mount the scope accordingly with the proper eye relief. The scope may come over the charging handle, and you may need to get an enlarged charging handle to make it easier to manipulate with the scope.

As far as the stock slop, you can put some electrical tape on the buffer tube for the stock to ride over, or you can replace the stock with one that has a friction lock... or, you can give up on trying to use an AR as a bench gun.

Not like that's going to happen. The only places I have to shoot anymore is at the ranges and they only have steel on the pistol range and the outdoor range I belong to so it is poke holes in paper or nothing. I could shoot standing I guess.

I was thinking when I bought this Mid MOE that the Magpul stock it came with was a petty good stock it will do for now.

I have found the cheek weld difficult as well. This was my solution:


The riser on the stock is very nice. It's easy to use and makes a very consistent cheek weld. I have no trouble "snapping in" with this gun and being in exactly the right spot in the scope. Also, I have this stock mounted on a civilian spec buffer tube. It does not wiggle.

I'm kinda like as cyphertext wrote. When I shoot with the iron (plastic) open sights, I am NTCH. The butt stock is two notches back from fully forward. When I shoot with the scope, the stock in three more notches farther back. My stock does have some slop in it, when not shouldered. However, when under a little pressure, against the shoulder, I haven't noticed the slop at all. Doesn't really create any problems with holding on target.

Very nice can you give me the make and model and where you got it it is just what I am looking for?

Here is another idea... Looks like it should work with the MOE stock... cheaper than replacing the MOE that you already have as well...

The nose to the charging handle is only for the 223/556 AR's. If you try that with a 308/7.62X51 it's bad juju. If you want to get rid of the sloppiness in you stock I'd suggest replacing it with a Magpul STR or ACS which have a locking lever which hold the stock solidly in place. Which is what I did. The CTR is another option but I like the cheek weld on the STR or ACS better. It's well with the $100 or so imo. I replace all the M4 type stocks on my 556 and 308 with either the ACS or the STR for the same reason on you don't like the MOE stock. To much slop in the stock..
The poster who said your check should be on the stock not on the tube (receiver extension) is spot on. As he said extend your stack so you get the proper eye relief with your check on the stock. Who ever told you to put your cheek on the tube doesn't know what their talking about.

You can't always get your face on the stock when using an adjustable stock. When I set an adjustable stock to a comfortable LOP, most times my cheek is partly on the stock and partly on the tube. (The exception is the UBR stock used on the rifle below. No matter where I set the LOP, my cheek is on the cheek piece, not the tube.)

Magload, can you post a photo of your AR? I suspect the scope mount being used is the wrong type. Most shooters benefit from using a cantilever style scope mount so the scope can be moved forward without over extending the stock

Here is a photo of a precision AR with a cantilever type scope mount. It lets the scope be pushed forward to gain proper eye relief. It also allows a greater range of adjustability. The scope can be set to allow a comfortable LOP to be used



Here is the same rifle & scope before installing the cantilever mount. You can see that not only does the scope have to be mounted further to the rear, but also limits where the scope can be mounted. This forces the shooter's head back and necessitates over extending the stock


What you need is a mount that lets you set the scope at a comfortable spot where you don't have to over extend the stock and don't have to run "nose to charging handle"

I have the Magpul ACS-L on my 300 Blackout and like the cheek rest enough that I'm considering ditching the A2 stock on my precision 223. Perhaps putting that adjustable gas block on the 223 to tune the gas system will enable to using a Carbine Length Buffer system with a 20 inch barrel. Have to think about that a bit.

Back to the original intent of my post I would suggest taking a look at the Magpul ACS-L, it is a really well thought out design with a very nice cheek rest.

GI field trick, strip of duct tape across the top part of the buffer tube and put back on the butt stock works great, saved me money for ammo, still using stock GI style butt stocks, and one cheap Blackhawk butt stock but did the same to it, no more wobble.

Here is the scope mount I am using Green Blob Outdoors (DARK EARTH) Tactical 1 Inch Cantilever Flat Top Dual Ring Scope Mount. I would post a pic but I removed the scope waiting for the Vortex Viper to come in. I been running the stock all the way extended and it seams to work better 3 clicks back think I will be ok with that. I like that stock in your top pic what is it and where die you get it? Don

Update: Vortex Viper just arrived it had been back ordered from Midway but for $100 off I tried to wait patiently. Well I should have noted that my mount was for 1" and this is a 30mm tube. Back to waiting. This time I ordered the Vortex cantilever mount for AR15s from Amazon Prime so it will be here Wed. This is a really nice scope compared to the 3x -12x Barska air rifle scope I was using. Don

First adjust the stock position to suit you. A lot of that depends on your arms and build. When you find the comfortable sweet spot, then it's time for the scope.

Mount the scope about about where you think it should be. Put the rifle in your hands, close your eyes and then shoulder the rifle naturally. Open eyes. Adjust the scope for eye relief moving the scope forward or back. Repeat until when you open your eyes the scope is in position with with you. Adjust height (different rings or one-piece mount) if needed.

The idea here is that when you shoulder the rifle you should be in alignment with the optic and be prepared to immediately acquire the target without fussing. Takes a little practice to be consistent. Next time you're at the range watch guys with ARs and you'll see them shoulder the rifle and then start fidgeting and moving around to get right with the scope.

Closing eyes and shouldering the rifle naturally is how I find the proper mounting position for all my long gun scopes.

Phil has opened the "gun fit" can-o-worms. There is a lot more to gun fit than just the "feel good" aspect of it. It's all about finding the set up where the gun mount becomes most natural.

They spend no time on this in the military. Maybe in sniper school, but not for the regular troops.

This may go beyond the scope (pun intended) of this thread. If anyone is really interested, I will spend some more time on this.

Please tell us more I like facts and I remember fitting rifle and shotgun stocks in the 60s. I wanted to be able to throw the rifle up to my shoulder with the cheek automaticly meeting the cheek piece and the scope eye relief right on then. The cross hairs should be petty much on target. A red fox getting rudely awaken in a open snow covered plowed field isn;t going to give you time to settle in behind the scope. A shotgun isn't much different when a quail and pheasant flushes you need to be looking down the top of the barrel when the stock hits your shoulder. I have installed many recoil pads on shotguns back then and know the fit is what makes a good shooting gun. Don

I'd like to hear more on gun fit. I also liked Phil's technique for scope mounting.
