Would buy again
This was my first build, and I'm hooked. Simple to put together. Palmetto was nice enough to put parts that go together in separate bags, so no shuffling through a bunch of parts to find the right one. Once assembled, I threw a set of mbus pop-up iron sights and a vortex strikefire ii on there and took it to the range. Fired green tip half the day and not a single issue. My next rifle will be a Palmetto for sure.

First Build
Using this to start my first build. Great intro and already finding ways to tinker more. Fully recommending this to friends & family as a way to get into the game before it's too late to do so.

I caught a hell of a deal!
$299 kit (in June) with $30 Reaper lower. Added Vortex spitfire and POF 4.5 lb trigger and shoots 3/4" at 100 yd. Never missed a beat or had any issues. Still looking to trip over this deal again. Everyone that shoots it, loves it.

You’ll love this rifle
My first build. Near and dear to me. It was simple to complete and she’s been always great to me. Feeds any ammo I throw at her. Stays reliable and a constant upgrade magnet.

Shoots well
Definitely looking to own a few more. The reason for the 4 star rating is the bolt seems a bit " gritty" when charging, I have ordered the Nickel Boron BC to see if it is better. Other than that, good looking piece.

The perfect rifle kit
For the price you really can’t beat it. Very good material and functions just like it should. Built my first AR lower with all the parts and actually came with an extra detent which was nice just in case I had lost one. Fit and finish is perfect and I’ll definitely be purchasing more! First day at the range I put 320 rounds through it and she worked like a champ with federal 55 grain. Since this doesn’t come with an optic I threw a atibal low profile red dot on it and love how it looks on the upper.

Besides a slight nick in the rail, it is perfect and getting better weekly, along with last years PSA upper, spikes lowers

Spikes lowers, the rest mostly came from PSA, my favorite company. Super charging handle, HK sights
This years and last years, both are awesome, no issues
