  1. OUTSTANDING procedures that ALL others I’ve read (and failed) are completely confusing not to mention even if one isn’t familiar with BDC sights that’s obviously wrong. Now maybe I’ll really start using my le6920 across the course and know this site as goood as my M1A’s. THANKS again.


    • Kick ass. I’m glad that it helped. I had a 20″ Colt HBAR for 15 years and I never really understood the nuances of the sight system. After all of this research and experimenting I hate that I sold it. I now have a 16″ Smith & Wesson M&P Sport that I purchased so that my kids could wear out the barrel with steel case ammo and .22LR with a conversion kit. I put a Rock River Arms A-2 sight on it and set it up with the Revised Improved BZ Method. I have an exact setting for 25 meters (I can’t shoot enough to tell a difference at 25 yards), 50 yards, and 100 yards. I can then put it on the “3” or “4” setting and hit steel targets at 300 and 400 yards. I’m pretty sure that I’m making occasional 500 yard hits, but 5.56mm doesn’t hit the steel hard enough at that distance to be heard very well. The next time that we are shooting it at the range I’ll have someone spot it for me and let me know if I’m getting hits.

      Please keep us posted how it works for you.
