I know that LaRue has been the standard for mounts for a long time. I am looking for a mount for my DMR which will hold a Viper PST 2.5-10x32. I am wanting a 20 MOA mount to help with some elevation.

So I have been looking at the LaRue LT745 and the ADM Recon. Both are available with 20 moa. I like that the LaRue has the qd levers on the ejection port side of the rifle so the won't hang up on my gear when slung; however the LaRue is more money.

I have read a few posts where guys are swapping their LaRue's for ADM's.

My questions for you guys... Is there truly a difference or any pros or cons between the two mounts? Is the difference solely cosmetic? If you had to buy one or the other, which would it be and why?

Thanks in advance for the input.

I have one larue 3 ADM recon i like adm better for one reason only .. the quick finger adjustment on tention is a plus my larue creat more gash switchin from rail to another because all rail are not square the same.larue need to force weather tight or too tight and sometimes creat scratches..adm you simple twist the adjustment 2 finger while swithin to another rail for perfect tension..

It's about bearing surface, especially on what would be considered a precision rifle, or even semi-precise.

The more bearing surface the better, Larue has the least amount of bearing surface and requires a special tool to tighten. Understand what the mount was originally designed for, AR rifles which are more than likely being used inside 100 yards. Errors are easy to overlook and will magnify at distance.

The very best mounts have the maximum amount of bearing surface on the rail. Alamo Four Star, GDI, etc...

You can use what you like, nobody will fault you on a line for flying the flag of a well known name brand. But if you want actual results, consider the conditions and what you plan on using the tool for.. if you want precision, more is better. Why do you think we torque rings to 55 in lbs or more with tactical rifles. We want them to work. If you are comfortable with finger tight, have at it.
 
#5
There is a question which is being missed here... What are the specs of the rifle?

Some people on this forum will take any opportunity to piss in LaRue's corn flakes.
 
#6
I only own LaRue, have never had any issues with the two mounts I own, personally being from Texas I bought LaRue over anything else for that reason alone I suppose, support the local stuff. Love LaRue.
 
#8
Theres no right and wrong on both my preference is the faster adjusting tension nothing agains larue since im using a lot of their products.whats the use of having QD mount if you need a special tool just to adjust tension.. LOWLIGHT has a point but ill have to dis agree some part yes sphur alamo or gdi has prove their names maybe makes u feel comfort thinkin giving you the most contact.BUT i can guarantee the mhyth of having 55inch torque on contactto rail, larue or adm can do it too.they even go tighter than 55inch lb..im using badger max50 even sphur is it realy necessary? Specialy on gas gun i mean how much of a recoil can throw off your larue or adm mount? Specialy on 308 cal..

it's not about pissing in anyone's cornflake's it's about the truth of the matter. Are you saying less bearing surface on a precision rifle is ok ? Are you saying we are all wasting our time torquing our rings ?

I mean, don't take my word for it, watch the Larue Cheerleaders at work in the Magpul Precision Rifle Video, that scope swap monkey drill was specifically done because "the Larue mount came loose" ... On day two, they showed up and had to rezero because Costa said, My Larue mount was loose... hence the monkey drill. If that is not pissing on their own shoe I don't know what is.

For an AR15 used like most use them, they work fine, precision wise, they have the least amount of bearing surface, (there was even an Army Picatinney Arsenal Test that proved this, the Larue mounts failed first) hence you are counting on that thin line of contact to secure the optic.

If you like, take the word Larue out and tell me I am wrong ...

Least amount of bearing surface, Distance magnifies errors, original design for rifles shot 100 yards & in... put all this together and if the specs were blind you would not pick them for a precision rifle.

So my rifle is a custom build, that I am planning on using out to about 600.
Specs:
Noveske Recon barrel, coated and fluted by Noveske
Noveske hand matched bolt
PWS carrier
Troy 15" hand guard cut to about 12.6"
Forgded upper and lower that I hand matched at a local shop
CTR stock, MIAD grip, MOE trigger guard
JP and Superior springs

I have been running a Comp M3 on it but I built a new LW for patrol purposes thus this one has become my DMR.

I use LaRue's for all my Aimpoint because they are on CQB rifles. I know that there are mounts out there that are "ideal" for precision; but a $300+ mou t is not in the budget.

As far as surface area. Would you say that a unimount type system is better than straight up rings? I use MK4 rings on my bolt gun and have never had an issue. It seems like the ADM has as much if not more bearing surface than just the rings.

I am not opposed to not having QD mount, I am just wanting a solid mount that will work on my rifle for range use and occasional tactical training type scenarios and fit in my budget. ($200ish)

CTown, don't forget about GG&G mounts. They're built extremely well and they hold zero very well. They're not polished and pretty like the others but they're also less expensive. I have a LaRue, GG&G and to me they're comparable.
 
#13
People should just ask what the best NAMED product at the cheapest price...

Be up front, say:

I want to brand my rifle with the top names but at the lowest costs, what cool guy products can I outfit myself with where everyone who see it will think I am styling ?

Cause I stand by my statement, if you removed the names and blindly listed the specs, and detailed the pros and cons you would go else where. It's only when you in Insert the Top Name Here, do people defend their compromises.

People should say, "we are happy to compromise as long as it comes with name recognition"
 
#14
OK. So maybe I should just ask this.....
I have listed the specs of my rifle and my intent. What do you guys recommend for a unimount in the $200 price range?

I am by no means dedicated to any one company and actually prefer to just get what works for me regardless of the maker. I have had LaRue's and have heard good things about ADM's. Both are right in my budget, thus my OP concerning both. I am open to any brand, unfortunately my wife won't let my wallet be open to any.

I was also looking at the Nightforce unimount, but it is a little more than I have to spend at this time.

At around $200, I'd buy Bobro before anything else in QD.

If GDI brought their prices down to $300, I'd probably change all my mounts to GDI. Since they're in the stratosphere of $500+, Bobro is the next best thing.

Not a fan of Larue mounts nor ADM.
 
#18
If you really care about precision get regular, permanent attach rings. That is how I have always gotten my best groups, IE good rings like seekins torqued to spec.

That being said a regular ADM-RECON mount would be just fine for what you are talking about, assuming it's an AR in 223 or 308. And don't bother with the 20MOA mount as that scope will have around 35-40MOA of up when zeroed no problem.
 
#20
I looked at the Badger One Piece Mount, but I was only able to find them in 34mm. I did find one in 30mm, under their ring section but it is .885" tall and isn't longer than any of the other manufacturers. Do they make the One Piece Mount in 30mm?

I have Bobro. It kicks ass. I actually spoke with him on the phone and he told me all about his system. I didn't really understand it. He has a double lever mount meant for Precision rifles.

Lowlight--can you comment on Bobro

A double lever mount for precision is something I'm definitely interested in. Any mention on cost or model number?

I'm not saying you're wrong, I'm simply saying that more info was needed and instead of trying to solve the OP's specific query you took the opportunity to point out the shortcomings of LaRue's product. The truth of the matter is that while your information is accurate and informative, it isn't worth fuck-all if the person reading it is shopping for a mount destined for a 4MOA "DMR" rifle because any shortcomings in the systems, short of flat out consistent failures, are grossly irrelevant at that point.

In the interest of full disclosure and to dispel the perception of LaRue nut-swinging - I bought one of their OBR optic mounts for my OBR and it is currently sitting on the shelf behind me. I personally don't like their scope mounts at all and will use Badger Ordnance for everything I possibly can (OMG an OBR with steel rings rather than a LaRue mount?! Blasphemy!).


CTown137 - If I were building a similar platform, I'd be looking very hard at either the BO one piece or a Bobro mount. I've never owned anything from Bobro but their designs intrigue me and I've heard good things about their company from industry professionals. I have owned some ADM mounts and never had issues with except for the fact that I don't personally like how their levers function and moved away from them. That is a personal preference thing and says nothing to their functionality.

The only ADM optic mount I kept is for a T1 on my M&P 15-22 because - wait for it - I thought it was less likely to break the plastic rail on the upper than the LaRue mount due to increased surface area and very different clamping method.

I feel similar... minus the cursing. ;)

For red dots, Larue, ADM, doesn't really matter to me... but for precision rifles and magnified optics, I don't really like either one.

Now that Bobro is nearly out with a T1 mount, i'll be selling off my last ADMs and replacing with Bobro... not that I feel a 2 moa non magnified optic really NEEDS it, but more because I prefer Bobro's lever.

Yes Sir, this is why I love Seekins big fat ass rings. Borbo and Spuhr are good for this as well, very chunky and lots of contact surface.

I went from ARMS to Larue to ADM and I have been happy with each progression. I use a dedicated NV scope hence the need for QD. I have no problem with RTZ or accuracy but if I didn't have the need to take the scope off for NV then I would opt for regular rings.
 
#31
Take a look at these two pictures and you'll understand what LL is saying. Larue makes a good product, but there are better choices for certain applications:

Nice pic, Mute. The ADM Delta mount eliminates the 3 piece set up (that both Larue/ADM use)to a base/ring top design. Right at $200, seems like a no brainer at that price for a QD mount.

I'm somewhat new to the board but would like to recommend the AAD mount. It's the same price as the bobro at SWFA and is a beast. I own one ADM mount and one AAD mount and the AAD mount is superior in every way except QD. The best feature is it's horizontal rings. I hate mounting scopes on vertical rings, much harder to level reticule. However my ADM mount has ran flawlessly and holds zero on my PST1-4 very well. It really all comes down to personal preference.

this... and i have 3 ADM's.. but bobro didnt make a 35mm 20moa mount... they are working on it now
 
#41
Anyone ever heard of 1-x scopes (eg..MK6 1-6x20) experiencing "optical distortion" when set at 1x in a 20moa cant mount? I had not heard of this until Jon from AAD gave me a heads up that this can happen, before ordering it! Which I thought was very cool of him, he could have just took my $ and I would have never thought about it. +1 to Jon Aadland

Kinda leaning towards 2nd choice of JP 34mm flat top scope mount if the AAD 20moa doesn't work out.

It's not 20moa but you still might consider the JP mount. I just ordered the 34mm version from Brownells for $165.52(mil discount) the 30mm version for your PST is $164.99(Civ) $154.29(mil)! I would have went with the AAD but I didn't want the 20moa and it is more $. +1 for Brownells price, in stock and $5.95 shipping!!

I would recommend the Bobro 30mm mounts. It looks like we have similar weapons. I had to go with Bobros 34mm mounts for a Leupold Mk6 3-18 for my Recce upgrade project.

As everyone has stated, he offers 0 and 20 MOA options. His mounts are designed to provide a solid interface with 1913 specification rails which results in excellent return to zero capability.

Now that he has his T-1 mount in production I am waiting for his off-set ring mount for my back-up/CQB T-1.

Andrew Bobro has had 34mm, 20 MOA, two lever BLAC setups for a while now. Our first mount in this configuration was rec'd last Sep. That's the problem with websites; they are generally way behind what the companies really have for products. Give him a call and he'll get you set up. He marks his 20 MOA mounts with a dimple under the front ring.

As far as ADM, we have used the bi-pod mount on an Atlas for some time and have been very happy with it. It's tough to find a bad mount these days if you're willing to spend at least $200. I would agree with Frank's comments though on matching the mount for the mission.
