Great pvs 14 mount for the cost - TRYBE Optics PVS-14 J-Arm Head Mount Adapter

This is the no nonsense way to mount your PVS 14 to your helmet. You can spend hundreds more for "Tactical" mounts, but this gets the job done just fine.

There will be a small "wobble" with the PVS 14 attached. Don't crush the mounting hand screw, that's not where the issue comes from. This is actually a designed in feature that, once you have completely and correctly adjusted the PVS 14 to your eye, will go away thanks to the flexibility of the eye cup. After I tried it, I actually didn't mind the "wobble" because it allowed me to look through the lens from slightly different angles and expand my overall field of view.

If you really can't stand the "wobble," which might be an issue with the PVS 14 in the up position, there is an easy fix. Take one of the spongy "Pluck-To-Fit" pieces that you kept from making that custom fitted case for you favorite rifle, and fold it in half and insert it into the female end of the bayonet adapter for the J arm, with the open end facing out. Make sure you insert it far enough so that the locking lug in the female side will still work. Push the two ends together. Make sure the locking lug is fully engaged, and you should see a big improvement.

This is a solid piece of gear, that is one of those really big cost effective items for your kit.
