This upper receiver is very well made and I'm glad I purchased this item. Fit and finish is excellent and I highly recommend to anyone who is looking for a good quality upper.

Well to start off, the dust cover looked worse than my factory one. They say it's new, but you'll never convince me otherwise. It looked like it had been ran over by a dually about 50 times. They say they get them new from DPMS. My answer is: NO WONDER! DPMS makes garbage. I finally get my rifle together and take it out on the range. I fire 1, yes 1 round and the forward assist falls apart inside the chamber and jams against the bolt carrier. It was almost impossible to get apart, but I finally did. I'm willing to bet it's also made by DPMS. I will not buy from Tactical Innovations ever again, and I suggest you look elsewhere.

I recieved it very quickly and the finish is beautiful and my barrel screwed in as it were made for each other. The barrel was from another company but I just purchased the STAINLESS STEEL SPIRAL PHANTOM FLASH. I cant wait to get it. You can not get it cheaper anywhere or better quality.

I am very pleased with the upper I received

This is actually an A4 upper. Rifle feed ramps. An M16A3 is an A2, full auto instead of burst. An A3 would be the same as an A2. Anyway, this is a great value. Mine was an Anchor Harvey. I mounted an M16A2 barrel to it. Fit and finish was great. These are good people to deal with. Communication, shipping, and turn around time was great. I would recommend them to anyone.

I recently purchased one of these for an AR build and am Very glad I did good quality Great price

The quality and construction is not too bad, the only problem is that they just don't fit any of the lowers I have. After I mounted the upper on my lowers (CMMG, DPMS, and Yankee Hill) they just wobbled, horrible fit. I would not recommend these for any of the above lower.

This upper receiver was so I could convert my A1 mutt to an A4 mutt. The receiver is nicely finished and functions just fine. My hopes were that it would fit tighter to my lower than the previous A1 upper did but there was no improvement in upper to lower fit. The fit could be better but I've had other brands just as loose. My upper had the take-down pin holes machined after anodizing. I hope this doesn't affect long term durability but only time will tell. I'd give it 5 stars if it weren't for my concerns over the take-down pin holes.

I have no purchased 4 lower receivers, and 4 upper receivers from Tactical Innovations. I've always received parts that were new and tight fitting (especially when mated with each other) as a receiver. I've never been shipped used or damaged parts. If you are looking for quality, with added features you won't find in parts from other manufacturer's, these are the guys to buy from. I've purchased several barrels, both 22, and 5.56 and again find them to be top quality, well finished parts that fit with precision. I purchased their SARC system for my AR's and had a problem with it initially, I sent it back, and they found no problem with it, but gave me the choice of either a refund or a new replacement. No questions asked. I give them 5 stars for quality, and customer care.

I purchased my upper and lower from tactical innovations on my first ar build. They mated up great and when I was breaking in my barrel the forward assist broke on the 5th round. It is easy enough to fix but that is the only problem I have had. With that being said it is a good product and its hard to beat the price.
