Ordered one from Brownless and they said it is ambidextrous. Got it today and don't know if it is. On the sling mount, the ball indent is on the right side of the mount, so the sling attachment faces to the left (for a righty). But on my shotgun, there is a little nipple looking thing where the cap screws on, so that the sling ball indent does not match up with the shotgun. I put it on and it seems to be stable, but I won't be shooting the gun until spring. These things ARE ambidextrous, right? I don't want to attach something to my shotgun that is not reliable.
