Took my brand new ar10 to the range for the first time to zero the sights.I was very upset to find that it hit 2 feet low at 50 yards.To make a long frustrating story short,I turned the elevation up to 600 meters and cranked the windage knob to get it to hit straight.Being a DCM shooter I am familiar with ar rifle and I am not a "happy camper"Guess this 1600.00 gun goes back to Armalite.Anyone else have a problem like this.
