    Incomplete Lower Built...

    Posted by Benet Gaytos on Apr 21st 2021

    Unfortunately my kit came incomplete as the castle nut for the buffer tube was not included. As I waited for other AR parts to come in I didnt open up the kit as I assumed it would be complete. When I finally had all my AR parts and started to build my AR was when I found out my kit was incomplete. It really sucks because you know once you get into the mindset to start this was a great disappointment as I had to stop my build. However, BRD really stood by their product and sent the castle nut which I am currently waiting on! I love that the company stood by their product and I would recommend this company and their excellent business practice to anyone--- but the delay was really a disappointment. The castle arrives when I have other plans so now my build will have to wait another week after it arrives.....this is the only reason I gave them 3 stars was the quick response of BRD otherwise I would have gave them a 1. If the part was there I would have given them a 5 stars.
