    I ordered this kit, upgraded the BCG and swapped to the 20″ (was only charged the diff in barrel cost) stainless spiral fluted barrel. Fit and finish were excellent, shoots great!!

    Great kit. Good value can’t complain. This is my third kit from Daytona and have never had a problem. No jams or missfeeds. Highly recommend this kit. I do live in a restricted state so i can’t use there lowers but my mill spec spikes works great with it. Great job!

    I’ve built 29 Daytona kits and they are the only ones I want to use, they’ve been great. Want to order another but it’s out of stock. Hope they get back into the game soon.

    This kit was amazing, the 80% lower was premium, and all the components were setup in individual bags for each step in the building process.
    Cycled flawlessly all 90 rounds at the range on first shoot.
    I would buy again if this kit would ever get back in stock. Great 1st Build.

    Fast shipping from Daytona. Never received a confirmation email but luckily my browser saved the page for me to get my order number. I only have 4 ‘complaints’ about this build kit.
    First being that the only missing part in my kit was a bolt catch spring. I had to purchase an oops kit from a local shop to finish the build since I didn’t want to wait days for 1 spring.
    Second, I’ve never owned a firearm with a cerekote finish. The handguard arrived with a few nicks on it and the lower scuffed up pretty easily while being completed in a jig. I’m not too sure if this is how all cerekote coatings are or if a cheap finish was used, but it’s still pretty good quality.
    Third, the receiver end plate included was way out of spec. It did not allow the charging handle to move. I swapped it with another end plate and it did not want to fit my other buffer tube either. My old end plate went on this new kit without issues.
    Lastly, this rifle seems to make alot of rattle noise when being handled. I’ve completed many builds recently and have not had any issues like this.
    Overall the finished product is a very nice looking rifle, will be ordering again if I Co across another good deal since many companies don’t include full kits like this anymore.
