    Lower AR 15 build kit

    Posted by Robert Mobray on Jun 5th 2020

    I am pleased with this complete lower set up. Everything was packaged well and all metal surfaces had plenty of shipping oil so as to rust up. Everything was there and shipping was surprisingly quick. Especially with everything going on in the world today. The mil spec parts are just that, mil spec Nothing out of the ordinary and no defect parts. Great Job BRD. I will be purchasing from you guys in the very near future.
