    AR 15 Lower Parts Kit

    I've ordered multiple times for BRD and it's for a reason. Great price, fast shipping and a good product. This kit fit's the bill for a lower price build if your looking for a range rifle to poke paper. Like the last few I've bought here it works just fine. Can't go wrong with this kit at this price.

    Great lower parts kit for the price. I have nothing bad at all to say about it. I like that it was organized in different bags.
