I would absolutely NOT recommend the M-223.
One member of our team, as well as a couple of our Facebook followers have had nothing but problems with the turrets.
They are VERY easy to bump off zero, now normally I would just deal with that, and make sure to dial back to "0" once you get ready to start shooting but surprisingly enough, they are also easy to bump into the "unlocked" position which allows the turrets to turn freely without manipulating the sighting system.
This is a huge problem, because there is no way to tell if the turret was on zero, when it became unlocked, or if it was already off zero when it became unlocked.
We looked at this issue pretty close and it's a pretty bad design flaw.
If you're just taking it to the range, go ahead, but make sure you inspect your turrets before you start shooting.
Not something I would consider after seeing the issues, and getting conformation from others as well.
