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.

Spikes lowers, the rest mostly came from PSA, my favorite company. Super charging handle, HK sights

Would recommend and buy again, perfect budget rifle build!
initial impression was a very clean looking upper. Lightweight, nice finish, clean lines. Assembly went smooth on everything except the trigger. I had to do a lot of filing on the sides where it pivots to fit my lower. 2 diff triggers went in my lower fine so must have been a minor manufacturing defect. Not worth knocking points off. Final assembly left me with a awesome ar for sub $400. Not including optics obviously. Would deff buy again and recommend to anyone looking for a budget build!
