I have an ACRO P2 on pre-order at Euro Optic. Still waiting for it's release.

There are one or two guys who shoot a lot that have had to send their Holosuns back a couple of times to get one that worked. We're talking the HS models that are all the rave.

Check out the Trijicon RSO. You don't have to remove it to replace the battery.
