"Very nice upper! I've paid more for lesser units. Finish is perfect! Fit is excellent! Can't believe this is the cheapest upper I could find! Bought it to build a carbine and Duracoat it, but it would be a shame to cover it up, gonna strip another rifle and replace it with this one and coat that other one. I'm very impressed! The coating is a nice flat black and the T marks are etched beautifully! Too bad I ran out of lowers... I'd buy more of these!"

"Well I was shopping around and this fit my budget. I recived it today the 24th and hurried and put it on. I will test it out when i get the chance to. I dont know why 1 guy put 3, maybe he is a snob and doesn't know what a good cheap buy is or he needs to cry about something."

"After reading some of the reviews I was skeptical but I went with this upper anyway and I gotta say I am highly impressed with it. The finish was great and it mounted to my century arms lower and barrel flawlessly. Best bang for the buck in my book."

"I was a little skeptical when I first placed this order but it fit into my budget for this build. I was very pleasantly surprised when it arrived. Finish was perfect, fit was nice and tight with no gaps or rattles at all. Color matched my Spikes lower very well. I was very happy when I realized that the dust cover and forward assist were already installed, saving me some time on assembly without having to deal with those two pesky items. A good quality upper for a very reasonable price. I am already ordering another one for my son's build."

"I've ordered several things from CTD in the past and always been satisfied, but this exceeded my expectations so much that I was compelled to write a review, which I literally never do. On the product great fit and finish. I\uFFFDve seen cheap uppers where the ejection port cover doesn't close just right. Not the case with this just as good of upper as you could pay twice as much for. Now for the part that blew me away....... the service. I ordered this part YESTERDAY morning, it arrived at my house at about 1:30 this afternoon. It was shipped from Fort Worth, which is about a 12-hour drive from where I live. I literately could not have driven to their store, picked it up off shelf and been home faster and this was standard shipping.Thank you Cheaper Than Dirt!!!!!!!"

"First of all, I experienced a very smooth transaction and super fast shipping to lower Alabama. Secondly, this flat-top AR upper feels very durable and matches the shade of my Olympic Arms AR perfectly. I purchased this item to convert my carry handle upper to this style and it only cost me $50 to have a local gunsmith switch everything over. I've already put 200 rds down range and am very impressed with the quality and great fit to my lower. So far, there is no play between the two receivers and it is just as accurate as before. I definitely recommend this item. At this price, you can't beat it. Thanks CTD! Be safe and happy shooting, guys!"

"This Upper came with the finish inside looking thin in some areas and thick in others. This does not affect the function of the bolt, just looks like it is sloppy finish in the quality control."

"Great Upper At a Great Price. And The Finish is Perfect. I used a DSA Arms M4 Barrel with M4 Feed Ramps. And it Performs Outstanding. Nothing Bad To Say About Del-ton.."

"Bought two of these for my first builds with extreme skepticism. They arrived and installed flawlessly. They are not range tested as of yet, but for the price you can't beat it with a stick. #truth"

"After reading other reviews and going thtoughy build budget i ordered one of these to complete my rock river arms lower. I was worried about the quality because the price was so low... but when it arrived 2 days later it was not only pf high quality, but it perfrctly matched my rra lower and rail. Put 150 rounds through it in less that half an hour with absolutly no issues. Great buy. I know ill be buying anputh for my pistol build"

"I bought this upper based on the reviews of others. The delivery was quick as usual from CTD. It went together fine but the finish is not the best. It appears weak and seems to come off easily form normal use. I assume it is milspec and so some slop in the fit with another milspec lower is to be expected. However, mine was really sloppy and required a JP tension pin to make it fit correctly which added to the cost of the upper. I know they say it does not matter, but I will never be convinced that if your upper flops back and forth while shooting it you are going to have good groups. It violates the laws of physics. I will probably pay a little more for a better quality next time."

"Mated this with a Mas Defense 10\" pistol barrel and headed off to the range. Shot 100 perfect rounds. Everything worked and fit perfectly. The finish was consistant when put together with my lower, looks like they were made together. I would buy another if I needed one."

"I purchased this upper for my first AR build, I have had no issues with it and it has performed flawlessly and I'm planning on buying the same upper for My next upcoming build. I can honestly recommend it to anyone building a rifle."

"Quality is what you'd expect from a much more expensive receiver. Color match is perfect, and it fits on a Sig M400 better than the factory upper receiver. Finish is perfect and feels very sturdy."

"This was my starting point for my first DIY AR-15. I'm running it currently with a palmetto premium BCG, magpul stock, ALG Defense Mil-Spec trigger (gieselle house brand). Stag Arms 1:9 16\" barrel. With a Black Dawn Lower. Guns flawless, the upper has been perfect throughout several rail changes. Thousands of rounds fired. Fixed sights, scopes, red dots, micro red dots. It's strong and comes ready to build on. I will never recommend spending your money on any upper other than a Del-Ton Mil-Spec. Anything else is paying for a name or emblem."
