First off (and it's a shame I even have to say this) don't turn this thread into an ARMS sucks/LaRue is great flame fest. Let's keep this discussion civil & unlocked folks!

I just have to ask... do YOUR LaRue mounts leave wear marks on your receiver??? I T&E'ed a LaRue Aimpoint mount about a year ago, and it started to leave pronounced wear marks on my receiver's rail (Bushmaster) after about 7 or 8 dismounts and reinstalls. A few others on this board have also reported similar wear problems, so I'm not alone or imagining things.

The vast majority of LaRue customers however, report no wear at all, so I'm left wondering... what gives???

I really want to like (and use) LaRue mounts, but I just can't be sure that I won't have a repeat experience.

Why did I experience wear (yes... the throw lever was adjusted correctly) when others have not???

Thanks.

No

At least not enough for me to worry about.
Link Posted: 9/19/2005 3:03:28 PM EDT
Yes, the levers are a harder metal than the upper IIRC. This will result in wear.

It is less wear than the Badger rings I've used.

I have only used an Aimpoint ARMS mount so I don't have a good baseline, but the ARMS Aimpoint mount does leave heavier MARKS, not necessarily wear, than the Larue ACOG mounts I use.

HTH...

Both my Larue and ARMS mounts scratch the park off when mounted.

I can't say they *wear* the rail, but they leave a mark.

Link Posted: 9/19/2005 3:52:44 PM EDT
Mine didn't. But I wouldnt mind wear marks. My rifles arent safe queens

Mine actually dented the aluminum slightly. It's my fault because I tightened it up too much and forced the lever shut, though.

ETA: And I don't care about the dent, either. It still functions properly. I'm talking about a very slight dent, and the mount re-zeroes perfectly every time.
Link Posted: 9/19/2005 4:18:40 PM EDT
Yes, but not excessively so, and not enough to interfere with function.

I've removed and replaced my Larue Eotech mount at least 20 times, and it goes back on as tight as it came off, and the marks are not any worse than after the first time or two.

Don't worry about it.
Link Posted: 9/19/2005 4:24:43 PM EDT
Hate to say it "Yes"
Link Posted: 9/19/2005 4:34:26 PM EDT
Yes my EOTech mount has left some marks on the finish. But hopefully with repeated removal no actually wear will accure. We'll see. Love the mount though!
Link Posted: 9/19/2005 5:07:09 PM EDT
Yes, every receiver I have seen that used Larue mounts had wear marks from the throw levers.
Link Posted: 9/19/2005 5:12:48 PM EDT


No, I didn't tighten it too much. That's what it took to stop the mount from sliding back and forth. Receiver is RRA.
Link Posted: 9/19/2005 5:20:45 PM EDT
Link Posted: 9/19/2005 5:24:03 PM EDT
yup./ kinda comforting though.
Link Posted: 9/19/2005 5:37:09 PM EDT
Who worries about this stuff? Not me. How is it going to clamp tightly and not leave a mark?
Link Posted: 9/19/2005 5:43:48 PM EDT
Is there a mount that won't leave ANY marks/wear available? I don't think there is. At least with the LaRue you can adjust to the wear accordingly.

My LaRue BUIS left a slight smudge looking mark. I have only had my ACOG mount for about 2 weeks and there isn't any marks yet.

Does the same on my AR receiver too.

ARMS mount have the little pads that shield the rails, none of mine needed adjustment though I've seen a 19S loose on Meateater's receiver, and on mine too. The pads are slightly annoying, they have to open up before the lever can be thrown in position.



My LaRue Aimpoint standard height mount was loose with longitudinal movements. I tightened it until it wouldn't move anymore, then the lever was so tight I couldn't unmount it without inflicting pain in my fingers. Maybe that's the way it's supposed to be mounted, alas my LaRue mount came with no manual, it was fun figuring out to tighten the bottom screws first, then top ones

Yup, mine have worn the anodizing. Doesnt worry me in the least, because Ive seen ARMS mounts do it too.
Link Posted: 9/19/2005 6:40:38 PM EDT

Enough to smudge the black, but not like its down to the bare shiny metal. The levers are just enough tight to kind of make a "crunch" sound when pressed in. And although I have them adjusted for a tight fit, I don't need a friggin' screwdriver to pry them open like some of the other company's products I've used needed.

All throw lever mounts wear the rails despite what some asshat might try to twell you to promote the sales of ARMS products. Problem is the ARMS rails cant be adjusted and wear the reciever just as much. If its a concern just hit the spot with some aluma black and remove about 90% of the shiney area.
Link Posted: 9/19/2005 7:55:38 PM EDT
If you have to ask, you don't want one.

or any other thing that may mark your pretty receiver.

Paint???

I don't know where you buy your upper receivers, but all mine are hardcoat anodized.

And that's my point... the lever was cutting through the growth layer of the hardcoat in very short order, and I'm sure it would have continued down to bare aluminum if given the chance.

What is the point of this post? ALL mounts will wear eventually. Your bolt will make some marks inside your upper if you shoot it enough too. Aren't you the same guy that started a thread like this in the past about a LaRue marking your upper but could never produce the pics?

I keep a couple of upper receivers in reserve. They are disposable parts after all and easy to replace.

Well it looks like I committed the grand heresy of even questioning the superiority & perfection of LaRue's throw lever design.

I beg everyone's forgiveness & I give my solem oath that it will never happen again.

Wow... and I thought Colt owners were bad.

Well, the LaRue mount costs more than the receiver. What did you expect?

It has nothing to do with you bashing on LaRue. It's the fact you started a thread you already knew the answer to. I must sound like a broken record but, ALL mounts will wear/rub/mark your receiver period. So why ask people to "be honest" when the answer is a given?

Relax.

The majority of posts say "Sure they leave some marks on the receiver, but it's no big deal."

I agree.

There's your answer, now go stock up on the mounts of your choice.

No Lumpy... give me a break.

I currently own & use two Aimpoint mounts (an ARMS & a PRI), and while it is true that both have left scuff or wear marks on my receivers, neither has produced the "gouging" that I saw & experienced with the LaRue mount in just a few installs & dismounts.

I'm just asking: why me? What did I do wrong that others have not?
Link Posted: 9/19/2005 8:49:12 PM EDT
No kidding NYP, you should never ask questions that you are genuinely curious about. You should just know all answers to all questions at all times...

GG&G Accucams don't tend to scratch or mark uppers. They are a retractable bar system though, as opposed to a rotating lever.

You mean yours has scratches, smudges, smears and dents? You didn't take it out of the shipping plastic did you, and if you did, PLEASE tell me you didn't take it outside or touch your bare hands to it.

ETA-sorry not trying to be a dick, just angrily avoiding studying for a test, and trying to joke around.

Airborne

ETA again...look at my post number; it's a shame we had to experience something that makes that number even stick out in our minds.
Link Posted: 9/19/2005 9:35:59 PM EDT
ARMS or LaRue (and I have both) all leave marks of some sort. The best point I've seen here relates to just buying replacement stripped uppers if you value appearences. The fucking price of these superific mounts is 50% more than the upper. So, if you want a sturdy optics platform in a quick-detach construct, they're gonna leave marks/gouges/ whatever it takes to make the optic not move.

Oh yeah...my charging handle leaves marks, my brass leaves marks on the deflector, and the dog gone collapsible stock is marking up my buffer tube. Everything is going to hell

Gimme_A_Carbine
Well, you are coming across as a dick.
I have 9 ARs. Of which, 5 have optics mounted.
All LaRue mounts. And if you remove your optics frequently
you increase the chance of wear marks, scratches and smudges.
As my 5 favorite rifles have. GG&G, LaRue ARMS etc given time
will leave marks if repeatedly removed-replaced.
Your belittling: "You didn't take it out of the shipping plastic did you, and if you did,
PLEASE tell me you didn't take it outside or touch your bare hands to it
"
reflects more upon you, than I.
My original reply to this thread was constructive,
ARs that are used, will be succeptable to finish wear.
Understood?

Everything you mount on a rail will wear the anodizing. Railpanels (even ones that are 100% polymer) and vertical grips will even do it.

So, to answer you question, yes the LaRue rings leave wearmarks. No worse than LMT or Troy BUIS, ARMS or Aimpoint factory mounts, KAC rail panels, or Surefire thumbscrews. Honestly, my sling wears on my sling loop almost as much.

But then again if you look at my personal AR, it'd be hard for me to name what device made what scratch, ding, wear mark, or whatever.

If the marks that LaRue (or any other) mounts make bother you, then you should be appalled by the brass marks and "wear" on your shell deflector and the wear on your lower from the ejection port cover.

God forbid your rifle ever hit a doorframe when clearing a room, or that you ever have to clear a spent casing by striking the buttstock on the ground.

No offense intended.
