PICKED UP MY FIRST DD a few weeks back and i must say it stands alone in quality of the AR's ive owned so far.The fit and finish is superior to the stag,colt,bushmaster and dpms i have owned.Before taking it out to the range i gave it a good cleaning then went optic shopping.I looked at eotech and others but desided on the trijicon acog in 4x.My first outing with my new prize was at the 2nd meet.The v4 was very impressive from the stock charging handle was smooth and trigger has crisp.Ran through 2 30 round mags and was an awesome shooter.I could have stayed their for hours shooting but didn't want to hinder my ODT brothers from their time on the range.Over all great shooter and well worth the exta cash.
