5 of 5 Fantastic Product and Prompt Service February 15, 2021
Reviewer: Eric K. from NC  
I just wanted to write to tell you about how pleased I am with your build kit quality.  I received my first kit the other day and was impressed with the staking and attention to detail it looked like was given to torquing the fasteners on everything on the upper assembly.  Also, the B5 grip that you all supplied is fantastic compared to the magpul grips that other brand kits typically use.  I also appreciate the fact that there was an aluminum trigger gaurd provided with the kit.  For the price of this kit, I am very impressed with the initial quality.  I was not able to test fire on a sled yet but if the accuracy of the barrel is anything like the quality of the rest of your kit I am sure I will be pleased.  You all will get my business in the future.  I just wanted to say thank you.
