1.25" 30mm cantilever AR mount query

[ChickNorris]

I'm interested if anyone has tried or uses one currently on their AR15.

Specifically, why they chose it & how it worked out for them.

Because the amount of correction necessary for me to achieve proper eye height with my new scope (not eye relief) from my (consistent) cheek weld is beyond silly. It becomes a jaw weld that is quite uncomfortable & fatiguing & inconsistent. This issue is with all the scoped ARs I've used but now it's fact with my daily rifle too. I'll own it as a flaw in my posture & will do the work if it turns out that's just what this is, however...

Yay, it's also hard to find & expensive-ish.

My point: before I spend the special order money &/or I start swapping stocks or drastically alter my fundamentals... please I'd like to see if this is a reasonable option that's solved a similar issue for someone. Anyone?

I use one, seems comfortable to use.

One reason for the high mount height is the clearance issue you’ll have with a variable optics Objective lens diameter clearance on your handguard. Another is the basic design of the AR platform. Which rings are you currently using and their height?

[ChickNorris]

Warne xskel30tw

[KS63]

What’s your optics objective lens diameter? 24/40/44/50mm etc

[ChickNorris]

24mm

Specifically Vortex strike eagle 1-6x24

[KS63]

Perhaps look at traditional two piece rings like the bolt action guys run. They come in shorter heights than AR specific mounts and can be found in most hunting/fishing stores. Hope this helps. If it doesn’t solve your problem, there are always adjustable cheek weld stocks like XLR, Luth and a few others. My XLR is super nice! Hope this helps.

[ChickNorris]

Yes, I am considering adjustable cheek rest configurations as well.

Thank you for the suggestions.

[ChickNorris]

Anyone?

[Tim K]

I just ordered one from NF, 1.125" tall for all the same reasons. I've tried rings, and there's the risk that you won't get the scope far enough forward. It worked out for me, but it's close. I've also added 3/8" foam pad to the stock back behind the farthest travel of the charging handle. That works really well, but longevity isn't likely to be good.

[ChickNorris]

I thought about a DIY rest if only to temporarily mitigate the hassle until I find something. My rifle is getting awfully cluttered...

[KS63]

Try this for an adjustable cheek weld. You need to purchase their buttstock and add this to it.

I did see that rest, among many & I see a fair use for much of it. I'm hoping I can sort this with a low mount & not muck with anything more. Also, I'm stubborn. I carefully chose every bit of my rifle & if possible, I'd like to keep it as it is.

Will certainly apply all that I'm learning for my next build. It's a while off yet, but I think I've decided that it will be for proper distance. Thank you again KS63 for the consideration & suggestions.

[ChickNorris]

Great information. Thanks Tim K.

That's the Nightforce A190 for those who were curious.

[Tim K]

A little update on the NF A190 (1.125") mount. It arrived last night, so I tried to mount my NF NXS8 in it. No go. The bottom of the turret housing contacts the top of the mount. Barely, barely interferes, something like 0.003", I'd estimate. I took it to my machinist, and he's going to skim 0.015" off it. I did try with the scope just loosely in the mount, and I'm certain I'm going to love the height.

Crazy that a NF scope doesn't fit in a NF mount, but there you have it. I sent them an email in case they aren't aware.

You can find good deals from a few web sites, including brownells and primary arms, who just ran or still is running a sale that puts them @ $110 ish

I use this one on a few carbines

That you like the height is encouraging, thanks for the update. Nice scope. I did the math, compared / contrasted the features & I'm curious what you'll zero to & your use for the rifle.

I believe my scope would fit without mount modification, however I have a probability issue that with my smaller optic & the 20moa cant, I might not have enough elevation adjustment for my purpose. I found another mount with 0moa, still no guarantee but less likely. It's nice but eeesh it is pricey.

If you’re contemplating buying a SPUHR mount just to get a lower ring height, if it were me, I’d rather spent $200 on an XLR AR adjustable stock and be done. A 20MOA mount actually gives you more elevation adjustment than a 0 MOA. Most people use 20 MOA cant mounts for long range shooting with high magnification optics (5-25x) to shoot 1,000y plus. Your 1-6x Strike Eagle is considered a short range scope.

Ok.
Yes it can.
Yes, most folks do.
Yep it is.

As another has suggested, you could use standard rings. I have run Leupold PRWs . You can really fine tune things mixing and matching bases and rings. Did I miss the reason a simple cheek riser is not an option. Magpul has them for most of their stocks for 10-20 bucks. Or you could get a retro lace on leather model.

[spqrzilla]

I wasn't happy with my cheek weld either but I concluded that it was not height that I needed but width. So I tried the Magpul STR carbine stock recently which is wider than that Magpul MOE I was using.

[Joe_K]

Anything lower than a 1.54” mount on an AR type rifle gets my neck so far out of whack I need to see a chiropractor. Currently I’m using a 1.93” height mount and it’s awesome, except when shooting prone, on which case it’s chin weld, although I can always add a cheek riser, but I can’t make the stock drop lower than the factory configuration regardless of what stock I’m using.

Never did get a chance to check out what resulted with Tim K's low mount. But after all that consideration I grew tired of the situation with the what if's & waiting. Finally just went & bought a couch for my face. I don't even remember which, the sls maybe. Some improvement with weld position though it's ugly as sin. It'll have to do until it doesnt.

Thanks everyone. I very much appreciate the thoughts toward my query.

Remember that the M-16 was originally designed with the carrying handle and high front sight post. As we have evolved to the AR-15, the height for optics is similar to that of the old carrying handle. Another problem with a low mount (when using a standard rifle scope) is that the charging handle is hard to access/function with a full size scope in the way.
