I really like the PRI mount, and the fact that it's adjustable means it is compatible with any other gear. It is expensive, and unlike the LaRue Tactical mount you can't leave the helmet mount arm attached to it.
You decision depends also on what other mounts you use. I use the ARMS/Cantilever mount on the Aimpoint and a SAMSON Flip Mount for a 3X Magnifier in place of the PVS-14 for day use.
And if the ARMS throw levers ever loosen up I can replace them with LT 17 & 17S replacement bases if I elect not to send them back to ARMS.
However, I really like the GG&G setup also, as you can easily switch the 3X and the PVS-14 on and off the same base.
And the LT mounts for both the Aimpoint/PVS-14 are also superb.
It seems, for tactical use, a SAMSON Flip Mount for the PVS-14 would also be valuable as it is for the 3X magnifier. For instance, transitioning from dark outside to illuminated inside.
Of course, if you get an IR laser, this is all immaterial as then the helmet mount is the way to go, but I still like the option of mounting the PVS-14 on the weapon or weapons.
