    This kit is high quality and a good price. I used this for my first ever AR build. Parts were nicely arranged in different small bags and the shipping was quick.

    I’m starting my first AR build, and it didn’t take long to discover that parts are very hard to find. When you do they’re usually kinda high (supply & demand, right?). The Black Rifle Depot had AR lower assembly kit including the stock assembly for a fair price. My order shipped fairly fast. I would recommend BDR to anyone who is building/repairing a rifle.
