Hello,

I picked up a LT-104 off the EE and I was recently informed that the recoil lugs are broken/messed up. Is there any way to fix them or am I out of luck? Here is a picture of the mount:



Any help is appreciated Thanks.

Looks like it was installed on a Weaver rail or not locked down on a pic rail correctly and fired multiple times. I'd dremel off the excess damaged material from the lugs and see if it locks up tight with no forward or backwards movement.  Did you know it was damaged before you bought it?

I knew it looked like that before the purchase but this was my first LaRue mount so was unaware that the small knicks would affect the end product.

Im going with this also.

I would go with a long file for more control only because I tend to slip with a dremel. Get those lugs back to as square as possible and you should be fine

I would send it in and see what LaRue can do for you.

Will still function fine on a regular 1913.

OP bought a used mount he knew as in rough shape and the first thought is to send it back to LT to see what they can do for him

You lost me

Especially when it will be completely fine on a regular flat top rail as-is.

This ^^^

That will work just fine on a AR.  Those little sections of material that were moved will not come into contact with anything on a flat top AR rail.  As stated, it looks like it was installed on a Weaver rail.

Thanks for the help everyone. I'll take a file to it tonight and just keep it on my beater upper. Just wanted to make sure I wouldn't ruin the mount more by taking some material off. I'm not mad at LaRue in any way it was my mistake for buying it.

I wouldn't even bother doing that, but you won't hurt anything taking the little burrs off.  The problem is rails like these, not enough contact between the lugs and the rail, so the corners get beat to shit.  This is just an MPX in 9mm though, which has virtual no recoil so it's a non-issue.  More powerful is where you see problems, as long as your rail isn't scalloped like that zero problems (and you probably got it for cheap, so good buy).
