"This kit was great. Took about 1 hour to build. Everything went together easy. Upper was fully assembled just build out the lower and pin it on. Very accurate and smooth shooting."

"I purchased this AR kit because of the price and reviews it had. I wanted to get all the parts I needed at one place because it was my first attempt at an AR15 build. The lower parts kit was very complete and good quality and fit my stripped lower without any problems. Highly recommend!!!"

"This is the one and only AR build I have done so I can't compare it to others but I will tell you I was a bit leery of \"building\" one. The AK build I did took forever and the purchase of special tools and equipment (shop press, jigs, etc) and wasn't much fun in the end. I finally bit the bullet on this with tax refund though, had to give it a try since I had a stripped lower sitting around anyway. Glad I did!! A rusty old hammer, some duct tape, an old punch, and some youtube videos is all I needed, an hour and a half later I had a top notch AR built. As far as I can tell, great quality all around and a price you can't beat. Comes with completed upper and headspacing checked... shoots great! Would, an will, build more now."

"I had the striped lower. Purchased this kit and it went together easily and without problems. No instructions were provided so I referenced the CTD videos. This was my first build and I laid out all the parts based on the video instruction provided by CTD. I was then able to put the rifle together with ease. I have yet to fire the rifle but anticipate no issues."

"Everything you need if you have a lower receiver. Upper assembly is already put together for you. Took me about 20 minutes to put it all together with my lower."

"This was my first build kit to mate to my Del-Ton lower that I purchased earlier. The parts went together without a hitch, everything fit fine. My gunsmith double checked my build and said everything was high quality. He was expecting that I paid a lot more than what I did (that's always good to hear)! The assembled gun performed flawlessly at the range and accuracy was above what I expected!Overall, I am very happy!"

"You cannot find a better value anywhere for this setup I did my first build with the ARR-706 (CTD Number) As a matter of fact I slapped this upper half on my 80% lower and was amazed how the pins lined up perfectly I did some dry fire testing, then loaded a magazine went out to my range and did live fire testing. My wife even noticed how giddy I was! It's great I'm hooked now looking to my next build."

"Just bought this delton kit everything you need is included. Everything fit into my Anderson lower like it was built for it. Very impressed by the quality and fit. I haven't put any rounds down range yet but I don't foresee any issues with functionality or accuracy with it. Thank you to CTD for the fast shipping."

"Couldn't ask for a better kit. Price was decent and assembly of the lower was simple. I had the entire kit put together in under an hour. Plenty of room to customize. I would recommend this for anyone looking to get a good rifle with a budget in mind."

"I bought this kit to finish my first AR-15 and it went together great. It took me a little over an hour to put it together but it got done. I have not had time to take it out and shoot yet but looking forward to doing this really soon."

"I purchased the 16\" mid kit along with a Del-Ton lower to complete my first ever rifle build. At the same time my father and I were working on another rifle from parts from different manufacturers. I could tell while building that I was having a much better experience and had made a wise choice to stick to all Del ton parts. I was going for a \"Plain Jane\" Mid-Carbine only varying from the Del ton design by adding an ambi single point sling attachment and a \"winter\" trigger guard. All of the parts went together easily. I took it to the range this weekend for a test fire and barrel break-in. It performed flawlessly, while we had numerous issues with the other (not Del Ton) build. It was also very accurate without a formal zeroing, with just the stock front sight and a basic UTG Compact rear sight. Stock trigger was decent too. Smooth and precise. No desire to run out for another trigger anytime soon. If the performance over time matches my experience so far this will be a great rifle."

"Fit was good on lower, kit was good for first build. however:Lower parts kit was missing bolt catch plunger - Other pieces in LPK had to be cleaned or filed burrs to function properly (take down pins + detents and fire selector).Plastic handguard had scratch, but replaced anyways for quad rail.Next build will go for better quality LPK."

"Giving this item 2 bullets because it came with two magazine catch pins, and no fire select lever. Otherwise is a good quality kit. Hopefully ctd will correct this issue."

"Great kit for an already assembled lower or stripped. All the parts needed to build or slap on and have a bunch of spare parts. CTD has a great price on this quality upper & parts kit for a fraction of the price for other high end AR's. I mean c'mon, its just an AR ... Why folks spend gobs of $ on varmit calibers is beyond me. Save it for big boy cartridges like .308 and beyond. At any rate thanx for a great deal and fast shipping on another great product CTD."

"It is my first build and it was a great experience and loved the kit. The only thing I've changed so far was the pistol grip and the trigger guard and I love it. Would recommend to anyone and allredy have."

"I had already put together the lower receiver minus the adjustable stock, so literally one minute to put together. It looks and shoots great. The only thing I would do to improve this would be to include a picture with labels to figure out what each pin and spring is for. All in all, A GREAT BUY and I will be buying another one, eventually."

"Verry good kit had no parts missing to complete it. Had it put together with in an hour, it is my first AR-15 so I was very excited to put this together. I had a few failure to feed problems with scared me but after using a pmag my friend had it worked perfectly. Surprisingly accurate for the price. Would recommend to anyone for a first build."
