Long barrel, tight groups - Aero Precision M4E1-E 20in 5.56 Complete Upper with Flash Hider

I have only shot about 550 rounds through this upper, but it handles so well and is very accurate! I took a fellow from my church shooting, first with handguns, and his self-defense gun was hard to keep on steel at 25 yards (very compact handgun), but when we went to a 100 yards with the AR, he couldn't miss! Granted, an AR15 is inherently easier to shoot, but it lends to the point: put a decent optic and get it zeroed, and this puppy is a real tack driver! No failures yet, though I may try to get a Daniel Defense BCG for easier cleaning and continued reliability. Wholeheartedly recommend!
