Adjusting LaRue Tactical Locking Levers
video version, for the reading-impaired Unload and check firearm before proceeding. LaRue locking levers are adjustable in infinite increments to accommodate any MIL-STD-1913 (Picatinny) rail, even those that are worn, or out of spec. Properly adjusted, the mount and optic will be fully-snug on the rail (you should not be able to move or “rock” the optic and mount). The tension on the locking lever is adjustable with very slight movement of the locknut, using the supplied 3/8 inch wrench. The locknut requires only SLIGHT MOVEMENT to adjust tension. Turning the locknut clockwise makes it more difficult to remove the mount. Turning the locknut counterclockwise makes removal easier. (Never completely remove the locknut) To adjust the lever’s tension: 1. Place mount and optic on the firearm, in your desired location. Move to another lug space if necessary to get proper cheek-weld and eye-relief. 2. Rotate lever(s) into locking position. a. If they can’t fully seat, rotate the locking-nut counterclockwise, until closing it requires some effort to fully seat the lever. b. If the lever swings too easily, rotate the locking-nut clockwise, until closing it requires some effort to fully seat the lever. 
As a general rule, adjust the tension until the lever is at a 45° angle when it makes first contact with the rail, then requires about 8-10 pounds of pressure to fully seat (about the same amount of pressure as pushing a thumbtack into dense drywall). Remember, NEVER EVER completely remove the locknut! 3. With levers locked, firmly hold the optic firmly with one hand, and the firearm in the other, then try to slide optic forward, reverse and rotate on the rail. 4. If the optic moves, slightly rotate the locking-nut clockwise until movement stops. 5. Now that you’ve adjusted the mount’s tension, mount the optic and zero the firearm as per optics’ instructions. Remove and reattach on same lug space then confirm zero. 6. If the optic does not return to zero, increase tension on the locking nuts very slightly, and try again. The Locking Slider: The Locking Slider keeps the lever from accendentally opening The Slider slides parallel to the mount. forward to lock and back to unlock (If it’s forward, DO NOT ATTEMPT to PRY the lever OPEN, it’ll damage the mount) |

I've often wondered, just what happens if you DO completely remove the nut?
The LT Tac Team comes and shoots your dog? Lifetime ban from future LT purchases? The Dillo Repo Team comes and snatches up all your dillos? |

Thanks, but now my wife is mad about all of the thumbtacks I just put in the wall calibrating my thumb.   Seriously though, great write-up. |

After reading this I got curious picked up the stealth grabbed the aimpoint and sure enough there was a slight fore and aft movement tightened the nut a little checked for movement had none,removed aimpoint and replaced applied 9.6 thumb pounds of pressure to the lever locking it and checked, no movement.

I have a SIG 522 that appears to have an out of spec rail - it mics out at 0.818" instead of the spec 0.835". Can a LaRue mount be adjusted down this far? What about an earlier LaRue mount, one without the locking slider?

No need - the used mount arrived today. I was able to adjust it down far enough, but it was close!

Thanks. I just discovered my eotech mount and BUIS both had fore/aft movement. I thought the lever were tight enough. I guess not.

Okay, 6-months ago I tightened all my LaRue mounts per the above instructions.
Today i noticed my BUIS and RASII aimpoint mount were loose again. Ive fired about 1,200 rounds in that time frame. What am I doing wrong? |
