They shoot loose if you run 'em hard, based on what people are saying who use LaRue mounts. I don't, so I cannot comment from experience, but every higher (500+) round-count course I have read AAR's on, LaRue mounts are full of fail, even when properly tightened (have to use Molle straps to remove them) before hand. I'm sure Mark will be in shortly with his shake-machine video and a wall of photos and military contracts and whatnot, but the fact remains that on .30 cal weapons, hard-mounts are best. Nightforce, Geissele, KAC, Leupold, etc.
Here is one such AAR:

Note: The Bobro also broke, although the poster (another site, not TOS), said that it seemed like an anomaly, that should clue you in to how much stress is placed on a mount in that application.

Just heard of too many issues with LT mounts on .30 cal weapons. I'd not. On a .30, hard mount it.
Please elaborate............

I saw 5 out of 7 LaRue scope mounts loosen on .308 guns in a Shrek "Heavy Carbine" class that I hosted in late 2013. John claimed that he saw similar results in every "Heavy Carbine" rifle class he teaches regardless of how tight the LaRue mounts are set-up due to the extra pressures inside of the .308s. My Bobro mount cracked at the cross bar that rests between the rail sections after running it thru the Shrek class on a .308 LaRue PredatAR.
For 5.56 guns I have never seen one loosen that was set-up properly. They are fine on 5.56 ARs. For .308 ARs I would only recommend a fixed/non-QD scope or optic mount.

Not sure if it was a fluke or not. I haven't seen anyone else have it happen. My Bobro did retain its zero on the .308 during the class. It didn't crack until a couple of months after the class when I moved it back to my 5.56 AR and fired several hundred rounds of 5.56 thru it.
Like I said, seen a lot of LaRue's on 5.56 mm guns and 12 ga shotguns without any issues. Use non-detachable mounts/rings on .308 and bigger calibers. ---Gary Roberts

Interesting. I've had nothing but positive experiences running Bobro mounts on both variable optics and RDS. First time ever hearing about a failure. Nevertheless, I won't run LaRue mounts. I have my reasons, and you just hit on one of them.
