First of all - you should have one heck of a gun. Ron used to make guns here in the Kansas City area and he built super guns that are still in use (and winning) in local PPC matches. Anyway, the "wings" on either side of the front sight are to block light/reduce shading on the front sight. Don't worry, as you start out, that in your haste to get the shot off you find you are using one of the wings for a front sight rather than the proper front sight blade - I'm guessing that most of us have done that once or twice. As far as aim point: I think general concensus is center mass at the 7 and 15 yard line; neck hold for 25 yards (though I have seen several top notch shooters using center hold here also); and, universally, neck hold at 50. I have a post - WITH NO RESPONSE YET - on what to do for the "quick 6" - center mass or heck hold??? I am still working on that one. Good luck, ken
PS I believe Ron is still alive and kicking. His son(s) are running the business (www.powercustom.com) in case you need anything for your gun.
