i have a pretty deep scratch under my rails from my LT150…just wondering if anyone else has them. not really worried abouit cosmetics but more the return to zero. i have taken my aimpoint of maybe 10 times so far
i did not post on the other site because i know so many idiots are gonna tell me not to worry about scratches :rolleyes:
Take pics.
Actually, you might have it backwards: we’re the ones that will tell you not to worry about scratchs 
However, if it’s digging into the metal then please do as Rob_S suggested and try and get some pictures.
Also please post who manufactured the upper receiver. The great thing about the LaRue mount is that it’s adjustable. I had a similar thing happen with an ARMS mount an there was no way for me to adjust it to fit tight against the upper receiver. As long as your LaRue mount is tight you should be fine.
Who made the receiver? I am afraid that a lot of upper receivers are NOT class III HA so the levers might dig in (especially if they are over tightened).
The lever should be tight enough so that the mount doesn’t move when you do a “push/pull” test. So you kind of half to play with it to find the sweet spot.

Yup, if you follow the directions all should be GTG. Most guys OVERTIGHTEN and induce the damage themselves…

Mark told me: “Adjust levers to where they are tough to close and a bitch to open.” When it comes to optic mounts, I’ve found that most people overtighten them.
Roger that… I was thinking I am entirely on the wrong forum there for a second 
The only upper I saw have problems was a CF C8 upper that we had intially put a 1.93 on a Colt upper then pushed it on to (via two people) the Diemaco upper.
(yeah yeah yeah) – I like to learn from my mistakes…
I swapped several LT mounts (1.93 for the SD and a LT EO) on Colt and LMT uppers for a few months with no issues.
i really did not know about the adjustability, hmm i’ll try to get some pics up by the end of the weekend…i guess cerro made the receiver, its a 6920
I hate to ask such as silly question, but what did you think the wrench that came with the mount was for?

…umm, a gift?..like the 'dillo opener or an LT cap!
Between this and the “scratch thing”, this has got to be a set up for the new moderator…I am not falling for it;) .
There is a tag in the package that says “Danger” Read Instructions".
Reading is fundemental, but apparently, also ignored…
Just as long as the “Fit and Finish” are good…(That was for you Pat…
)
When I was active duty we had a saying R.T.F.M. 
Now that I’m in the corporate world I have to use the politically correct version: R.T.M.
And yes, it goes largely ignored
Mojo58,
I’ve quit saying “bitch to open”. Because it turns out that one man’s bitch is another man’s queen. :-/
Some folks idea of a “bitch to close” means a five pound hammer and I foolishly did not take that into account.
The revised instructions will have “color glossy photographs with a paragraph on the back of every one” - Arlo Guthrie
Jokes aside, it appears that the better method is to adjust it to where the lever meets solid resistance at about 30-45 degrees from the centerline of the rail. Another method is to adjust until the mount cannot be scooted back and forth on the rail…turns out that that’s about 45 degrees.
If anyone can 'splain that better, I wish you would, because I need an easy set of revised instructions to send out with the mount products.
We have shipped tens of thousands of the lever stuff and had but a couple of complaints…due to over-tightening. Out of the thousands we’ve made, none have broken yet and that’s testimony to the 17-4 stainless we machine them from.
I do see pics of a lot of stuff in use over there that our stuff is mounted to and none of it seems to be in “mint condition”. :-/
Oh yeah, and we know that an occasional drop of CLP on the lever minimizes even the littlest smudge - as always, everything is better when it’s wetter. 
Mark
well i’m looking for the camera, i packed(about to PCS) and i got the mount from CT Supply used…hmm i feel like at TOS now its weird
Actually at “TOS” most would have advised that beauty is more important than function. You will not find that here. Reliability and function are king here. Looks are dead last on the list. I think most here would prefer the 6ft drop over the shoulder onto gravel to make sure everything is secure on the weapon.
I do however understand that you were concerned that something was wrong with either the mount or your receiver and wanted to double check that everything was ok. As you found out, the lever needed to be adjusted so I hope you got the info you needed.
C4
Rats, bought it used, probably didn’t get the wrench or instructions. :-/
We do adjust the levers here to the middle of the the 1913 spec…but a used unit could and probably has been reset to some other rail and …
Again, for those of you obsessed with “absolute mint condition”, occasionally put a wee bit of lube on the cam area. No biggie.
