Is there an aftermarket product that is designed to help me raise my cheek weld on an A2 stock that is part of an AR-10?

I'm trying to get a more "natural" position behind the rifle where I don't have to muscle/raise my head to look through the scope.

I did a bit of searching but aside from some stock packs that don't really fit the bill for what I'm looking for, I didn't come up with much.

The problem with the Delta-type cheek pieces (which I've not see for an AR-10) and other aftermarket cheek risers, or with adding the DIY materials, is that you'll likely get interference with whatever you add with the charging handle. OR...you have to move the riser back so far to clear the CH that you end up contorting your positioning on the rifle back to get on the riser properly.

Knowing more about your setup would help on this issue. As someone said before, using the proper rings/mount to lower the scope down some is the first step I would take if you've not already done so.

The other option is something like the Magpul PRS AR-10/SR-25 buttstock with an adjustable comb riser. Again, for some people, this places the cheek riser back so far because of the longer CH that you end up half on/half off the riser or otherwise contorting your head to fit properly on the rifle. It all comes down to what you, personally, need/want but the PRS may be worth a try.

An AR10 A2 stock is exactly the same as any other A2 stock. I use the old nose to charging handle hold and I have never had an issue with finding a good cheekweld with a scope or irons, I just mount the scope to the same height as the irons. I had a PRS once and after adjusting everything and getting it perfect, I had actually adjusted it to the same dimensions as an A2, so that came off and an A2 went back on. Saved myself $200 too.

If your deaed set on a cheek riser the snap on delta is the cheapest easiest mod to try that doesn't involve tape, but the best fix is probably going to be proper rings that bring the scope down to manageable heights.

This is what I have found to work the best for me. I put a standard Eagle stock pack on my A2 stock. If you put it all the way back at to the rear to the point that the back of the stock pack hangs slightly over the end of the stock and pull the front strap super tight, the charging handle will clear it.

I have one on my KAC m110 at work and I also have one on my Noveske AR10 with a Nightforce scope and extra high rings. For that one I added a strip of mouse pad underneath the pack to raise the comb height up to the proper level.

You are missing the point...the AR-10 charging handle is longer than the AR15 by a good bit and while the cheekpiece will absolutely fit on the stock body (which obviously is the same), the Deltas I have seen won't let the charging handle of the AR-10 pull to the rear far enough to charge the rifle because the relief doesn't go back far enough into the cheekpiece.

I have a flat top rail and on top of that sits a Badger 20 MOA rail then some 34mm Badger rings (USMC). I guess I could remove the 20 MOA rail in order to lower the setup a bit. I'm not shooting out that far anyhow.

The closed cell foam technique sounds like it would work also. Maybe I'll give that a try before I break the scope down.

For what it's worth I'm running my AR-10t w rings straight on the flat top rail and I am still able to dial enough elevation on my scope to reach out to 1000yds.

If it's any additional help, I'm running a PRS and the comb doesn't interfere w the charging handle, but I also installed a spacer from DPMS that goes between the reciever and the stock, moreso to fit the rifle to me better bc I had the butt of the PRS extended all the way and it was just barely long enough for me (I'm 6'4")... at any rate, that spacer would fit w an A2 stock and if you can tolerate an extra inch in your LOP that may allow you to install an aftermarket item like the delta riser and still clear the charging handle. (also it is listed as an ar-15 part but fits the ar-10) You will of course need to mount your scope an extra inch rearward to maintain your eye relief.
