    Ordered this kit recently for my first AR build. Kit came pretty quick, withing about a week. I opted to not get the 80% lower as I already had a spikes pineapple grenade. I did however upgrade to the stainless barrel and the titanium nitride BCG. Setup was quick and easy, parts for the lower are in color organized bags to make it easy for first time builder. Took it out to the range yesterday for the first time and it worked great. My friend was envious. He said he thinks its lighter than the AR he laid a grand for. The trigger breaks pretty light for stock. Not like other heavy stock triggers. I’m happy with my purchase and I will buy another kit from daytona again. Thanks for my first AR!

    Bought this one for my first build. Came out perfect. With no experience at all i had it all done in half day and was shooting it that afternoon. Just ordered my next ar15 kit from daytona tactical as well for the wife to have her own.

    This was amazing. My only complaint is that the trigger guard wasn’t a magpul fde. I got the kit without the lower because I already had a lower. Awesome that they give you the option to not receive a lower. Got nothing but complements on my rifle.

    Great kit, this was my first build. The kit was great quality,the parts to build were in separate bads which made it easier to build, overall quality of the Ar was top notch. I would definitely recommend and i will probably buy again.

    I’ve purchased 2 of their 16″ flat dark earth 80% kits. Love the service and the quality of their product. I have recommended them to everyone interested in building their own.

    Bought this one for my very first build last summer. Came out perfect. With very little experience I finished in less than two hours (including some time spent looking for a detent I shot across the room). I took it out the next day and worked great with metal magazines. Had some balkiness with plastic ones which I hope will be cured with more breakin.
