Great upper, no major problems but did have the forward assist launch out while firing it found all the parts and reinstalled it works still. Rails are very beefy MBus forward sights get hung out some but still a good upper (Posted on 8/12/2016)

With six children and seven grandchildren this farm doesn't lack for hunting guns. We have several AR's in both 223 and 308 that we use for hunting varmints, deer, bear and even moose. I wanted a light weight quick handling carbine for around the farm and farm truck use for coyotes and other varmints. Something that could be tossed in and out of trucks and equipment that didn't cost me a small fortune. This upper fits that need perfectly although it really is to nice to beat around in a farm truck. The fit and finish is outstanding. There are zero marks or blemishes anywhere and the hand guard rail is seamless to the upper. The best fit I have encountered on any upper thus far. The color matches up perfectly with my spikes lower and two of my Windham lowers. The Keymod hand guard is very light weight compared to a Midwest Industries I have. I placed a Leupold VXR 1.25X4 scope on it and stepped out back on our range. To check function I fired several different brands of surplus ball ammo from 55 grain to 62 grain along with some cheap Brown Bear 62 grain hollow points. Not one malfunction of any kind and the ejected brass on all brands landed 6 feet away in an 8" circle at the 4:30- 5:00 o clock position. Shooting off a bag with 55 grain surplus ball ammo I was shooting just a hair under 1" three shot groups at 100yds. My Hornady hunting loads with a 55 grain SP at an avr 2850 fps were shooting between 3/4 and 1", 3 shot groups at 100yds. I am sure once it gets broke in better it will be an honest 3/4" gun with the Hornady hunting loads. The parts were shipped on time and packaged VERY well. Everything was sealed in plastic and wrapped in foam and/or bubble wrap. It made the trip clear across country in good order. This was my first purchase of an Aero product I am so impressed with the value and quality that my plan is to order two more one in 300 Blk and another in 6.5 creedmore before this year is out. Great service and good prices on quality built parts! (Posted on 3/24/2016)

I purchase the 15'' quad rail hand guard on the 16'' barrel. It is a complete upper that is worth twice its price. The hand guard is very well made and a home defense weapon by itself. The upper and finish are flawless. I replaced the A2 birdcage with a VG6 Gamma and it really completed the look I wanted. This is my second build with AP and it wont be my last, I have another lower on stand by. (Posted on 1/7/2016)

As a former Marine and having worked on quite a lot of M16/M4 and AR's of a few buddies of mine,must say this upper receiver is amazing and fun to shoot. Ordered this upper a couple months ago,got around to shooting it last week and must say it runs very smooth!! Along with their nickle boron BCG makes this upper very fun to shoot!! Best bang (no pun intended) for your buck. (Posted on 12/19/2015)
M4 Enhanced Upper Review by Douglas

This is my first AR15 build, and I am highly impressed with the quality of the Aero Precision parts. Fit and finish are excellent. I purchased the M4E upper with a 15 inch Mloc hand guard. This was mated with an Aero Precision short throw safety selector lower. What impresses me the most is the usability of the rifle. With the long hand guard, and a Magpul Mloc AFG the rifle can be securely rested without affecting the barrel point of aim. The hand guard is very rigid, and all stress goes into the receiver. Terrific design, light weight, and also very cost effective. I am very happy with my rifle. (Posted on 11/24/2015)
