So recently a friend of ours we had review our FX3 3X optic flipper mentioned he had astigmatism which was making it slightly difficult for him to operate his red dot, magnified or un-magnified. He suggested we make a mount for the Primary Arms ACSS Cyclops which is what we've done! Not only can you mount the Cyclops, but it also works flawlessly with our FX3 3X magnifier flipper. Currently we're running a promotional sale that makes the FX3 $20 off for the month on June. The Acss Cyclops mounts using our T-1 micro dot version low mount.
