"The only reason I didn't give this 5 bullets is because, despite the kit including a few extra detent springs, the bolt release lever assembly was missing it's detent spring. Easy enough to locate from a local FFL who was more than happy to sell me an $11 lower spring kit. Since the upper comes completely assembled, combining your own stripped lower and a little bit of time to install the trigger group, take-down pins, bolt release lever, pistol grip and buttstock will leave you with a nicely functioning rifle. Note: This rifle kit doesn't include any kind of rear sight, so if you plan on keeping the front gas block/sight assembly, you will need to acquire either a carry handle with integrated rear sight or a rail-mounted rear sight. Installing optics may require replacing the front gas block/sight assembly with a low profile gas block."

"I purchased this kit thinking they would have things worked out by now and all parts would be included, I was wrong. I called CTD and they sent me to Del-ton and said they would mail the parts out. I received great service from CTD and Del-ton and my parts were shipped without any cost to myself. I Wouldn't hesitate to buy this again."

"I purchased two of these, for my first-time builds. They were both well packaged, complete and CTD had theirs at my home in less than 24 hours of ordering! The fit and finish were great (IMHO) and the kits built into my lowers in no time at all. I have open A2 style sights on one, a red dot on the other. 100 rounds through each with no failures what so ever! I WILL be getting more...."

"everything assembled as expected. A1 quality. price is great. UPS beat up my box pretty bad, CTD should double box their kit for that matter."

"Bought this kit as part of a gun build. All the pieces were bagged and packed in egg crate foam. All the needed springs/pins were included and it went together without a hitch. Only gripe is there is no mention that a rear sight isn't included. Not a huge deal, but would have been disappointing if it had not been mentioned by another reviewer."
