I don’t care about “Nike Swooshes”, and I don’t want to discuss the founder’s personality or worth as a human being. I am curious about the interface, and how it’s done for people who’ve beat the crap out of it. A lot of the newer mounts have larger surface areas/clamping surfaces. I am curious if there is any merit to the idea that over time (such as Grant of G&R tactical alluded to secondary to his claimed high-speed videos of weapon mounts during recoil, where he claimed that the LaRue system could create a dent which grew and grew with use), the rail could be dented and zero lost/the mount needing to be adjusted again. Especially after an impact to the optic/mount.
Anyway, legitimate design shortcoming, or BS? Anyone seen the nut come loose, the rail dent, the mount loosen up, etc. in the real world?
a bunch of years ago I had an acog mount turn into a paperweight, the mount came apart at the QD lever and they wouldnt replace it. Then when the 45 degree offset mounts became popular I had one that the material stripped out while I bolted the optic to it, without me knowing until the optic fell off after heavy use. They wouldnt replace that one either.
The thing I don’t like about Larue is the levers/clamp rotates directly on the upper receiver. And yes, with removing the mount enough times, this could gouge the upper receiver enough to produce the results you explained. It’s not very likely, but it can happen.
Honestly, I think ADM has the best QD mount out there. The Bobro is an excellent mount don’t get me wrong, but I have my woes with the lack of adjustability. The springs in the Bobro rail interface just don’t seem like they would hold zero under really hard use. I can throw the zero off on my Bobro-150 by twisting the Aimpoint PRO. I could do the same with the ADM mount, but not nearly as much. If Bobro would add an adjustment to make the springs in the rail interface tighter, they would have the perfect mount.
I just don’t see how this is possible. The Bobro is under constant spring tension. If you manage to minutely compress those two springs, they will return as soon as you let go. So unless you deformed the metal…I don’t understand? Have you verified this with live fire?
It’s not thrown off much, but it is thrown off a little. And no it does not return when you let go. It is off a little. I would compare it to removing the optic and re-installing. Is it good enough? Probably, but that’s subjective. If the rifle gets dropped, I wouldn’t trust my life to it still being zero’d. I definitely don’t think it is bulletproof like some of the other mounts.
Personally, I want my mounts to not move at all. Even if the rifle gets dropped.
FWIW, I am currently using the Bobro mount with my Aimpoint PRO, so I do think highly of it. But through my experience, ADM retained zero better.
I own three Larue mounts on three different rifles. I have had zero issues with them. I also own an ADM Delta mount for my SCAR-17 and so far so good.
I know many people personally with Larue mounts who have had zero issues with them as well. Occasionally, they sell a stinker or they can wear out. However, it’s a good product compared to the original ARMS mounts they were meant to replace. I have yet to see any data showing ADM or Bobro mounts to be superior. They appear to be on par with Larue, but not necessarily superior. If someone can get ten mounts from each company for an Aimpoint ML3 and torture test them, that will settle part of the debate. They can then do the same for similar style scope mounts, etc.
I’ve owned a LT-150 in QD and in VFZ and one two different rifles bolt mounts would walk fore and aft on the rail. Yes, I know how to adjust them and I had the QD tightened to the point it was no longer QD and there was still noticeable movement after dropping the bolt a few times.
The recoil lug on the bottom is way too small and allows the mount to walk.
The LT-103 BUIS with VFZ I have is fine, but it’s much lighter than an Aimpoint + mount so it doesn’t gain enough momentum to move.
I have no use for LaRue optics mounts, the Chinese made cantilever mount that came free with my Aimpoint from Primary Arms was more solid than the LaRue.
Two Aimpoints in M68 CCO mounts which have been dropped many times in classes and never lost zero. Taken off multiple times for cleaning and not lost zero.
I have a NF 2.5-10x32 in a LT104 which was dropped directly onto the scope and did not loose zero. Taken off for cleanings and did not loose zero.
I also have a Steiner 5-25x56 in a LT112 but it has not been tested for toughness yet.
I have not noticed any significant gouging or marring on the underside of the top rail where the cam interfaces with the rail. There was a small amount of finish removed on my BM rifle, but nothing on the BCM upper, VLTOR upper, or LaRue uppers.
4 Larue mounts total. 3 on aimpoints one lt 104 that rides on a 5.56 gun. I have repeatedly removed the scope and put an aimpoint on with no ill effect.
Basically, I am in similar situation with two Larue mounts (EOTech riser & LT111), an older Knight’s set of rings, an ADM Delta on my SCAR, an ADM Recon on another rifle, and a Spuhr on a bolt gun. The Larue mounts have been durable and haven’t had any of the “internets” issues with levers or other things. I also have Larue mounts for bipods, weapon lights, etc. No issues with quality control, fit, durability, etc. I had the LT111 on my SCAR until the ADM Delta came out in 34mm. The only reason I changed was that the ADM is a bit slimmer and has more room for my fat fingers around the charging handle - not that anything was “wrong” with the Larue mount and I didn’t like the angled charging handles very much. The SCAR is the only rifle where optics are swapped with the barrel, so the QD features get used seldomly on everything else. Because of this, I can’t honestly say how much wear on the levers and clamping mechanisms I have really done.
From my own experience, Larue makes a good product, so does ADM and KAC. Spuhr, on the other hand, makes functional art.
LT optic mounts are the only ones that I own. I have one mount that I have had since 2005 and it is still good. As Customer Service goes I have found no better. I have messed up some stuff ( totally my fault) and they have always been very descent. I have tried both Borbo and ADM and I was far from impressed.
Currently I have 4 ACOG mounts, 3 SPR 104, SPR 193, LT152, LT110, 2 RMR mounts, DBAL mount and about 8 light mounts. So you can say i have a wide test base to make a judgement. No issues with any of them.
All of my optics come on and off my rifles and I have never had an issue with a loss of zero. As far as I am concerned there is no better mount.
I have a handful of Larue mounts, for several Aimpoint’s, ACOG, a few scope mounts, etc - no issues with any of them. I don’t know about Grant’s testing, but I have had zero issues with mine, when properly adjusted. I’m pretty far from a ‘hard use’ case, though I suspect. I tried two ADM mounts, once for a Micro, one for a scope as they both came with them, and just didn’t care for the adjustment system. But I’m sure they are fine mounts, plenty of folks like them. Haven’t tried the Bobro, but to be honest I’m happy with my LT mounts so really haven’t seen the need to look elsewhere. Mark’s a bit of a lightning rod character and seems to have more detractors b/c of it - whether deserved or not - which tends to spill over into reviews/comments about his products, unfortunately.
Very disappointing. Part of the reason I buy there stuff is this:
Our strong point is our guarantee - “If you ain’t happy, then we ain’t happy”. This “Lifetime” guarantee means as long as I’m alive you can return any defective LaRue Tactical manufactured part for a full refund or exchange.
For your two anecdotes did they use this as an out?
Warranty does not apply to any problems or failures that arise from improper installation, improper maintenance, improper storage, improper use, or modification by other than LaRue Tactical.
Repair to damage outside of these terms is not the responsibility of LaRue Tactical, and will be handled on individual basis.
I own 2 LT mounts and one ADM. All three seem like good quality items. The only “hard use” I have done with any of them is the LT fixed rear sight on one of my carbines. The gun and I exited an ATV at about 25 MPH and my whole weight landed on the gun, which impacted the ground “rear sight first”. The sight dug a 4" x 2’ divot in the soil, but did not budge. The pigs I was after were lucky in that the sight was so full of dirt that I could not use it, but it otherwise did not damage or move the sight at all.
I have a micro sitting in a LT mount on my duty rig. Its my 3rd LT mount. I’ve only removed it a handful of times. I don’t baby my equipment - the gun has been banging around in my squad car for 2 years now. It hasn’t gouged the receiver, loosened, or lost zero.
I’m under no illusion there may be better mounts out there - actually, my next aimpoint mount likely will be a GDI. But LT mounts, to me, have proven duty capable.
