According to a number of people, the recoil on an AR should be less since a good portion of the recoil energy is directed towards cycling the bolt. I've got a few AR-10s that seem to kick worse than a bolt action .308. I think the movement of the bolt increases the felt recoil to the shooter.
If you are considering the LaRue but are concerned about perceived/felt recoil, consider swapping out the muzzle brake. The Little Bas$&rd supposedly reduces felt recoil between 30-50%. Not sure if the reports are accurate, but something to consider.
I've got a Savage 10BA in .338 LM. The thing has a huge muzzel brake, and as a result, the recoil is comparable to a 12ga slug. It is UNGODLY loud and will blow everything off the bench, but it does a good job of reducing recoil.
Just my $0.02.
