My team got the daniel defense 10.5 in barrels before our last deployment to the stan and they performed extremely well. Everybody was tagging steel and personnel
out to 600m no problem. SOPMOD DD upper is Free floating and comes with front flip up site and runs like a champion. Every-time we have a shot out barrel and it fails a gauge, we send it in to get re-barreled. I am not convinced when this process happens anything really gets done. When I got the DD upper I think it was the first time ever in the military I received a brand new barrel which is sad but Im glad it happened a lot of bad guys in the dirt courtesy of those little guys.
