    I’ve ordered multiple times for BRD and it’s for a reason. Great price, fast shipping and a good product.

    Great starter kit

    Building my first rifle and got these parts to go along with my stripped Anderson lower. Parts came packaged in mini packs to keep everything labeled and well organized. As a beginner, these parts are well worth the price. The grip is also a good placeholder.
