    AR-15 Lower Receiver

    Vey impressive lower. Well built, chunky, includes several premium features like adjustment screw for adjust of upper and lower as well as the option to install buffer detent under the grip rather than the end plate. I had to look at it for quite some time to find the blem and when I did I had to laugh: it's hiding in plain sight. Great lower at a great price.

    I used this lower to build a new .350 legend for the upcoming night hog season. This lower is a spectacular, tight-fitting design, With a great finish and a ridiculously awesome price for what you get. Order one today.
