"I honestly can't find any sort of practical test that would harm this receiver or make it in any way inferior to an aluminum one."- Tom @ Apex Gunsmithing Experpt from a Third Party Review at


Federal law requires that you be 21 years or age or older to purchase a stripped receiver or frame. If a frame or receiver can only be made into a long gun (rifle or shotgun), it is still a frame or receiver not a handgun or long gun. However, they still are "firearms" by definition, and subject to the same GCA limitations as any other firearms. Please enter the phone number, city, and state of the licenced dealer you would like it shipped to when ordering.

    Overall the lower is pretty nice. It did fit my upper a little loose. More so that the other two 308 AR's I have that are aluminum. The rifle I built with it is kind of a "poor mans" SCAR and in that it is very light and runs well. This is my first polymer lower.... But probably not the last one I'll buy from Tennessee Arms.

    Excellent for the price

    I have yet to mate this with an upper as the product I am looking to buy is out of stock. That said, the lower appears to be of good quality. It does have a bit of a cheap, plastic-y feel to it, but it seems to be quite sturdy.

    Havent shot it yet but it fit well to my aero precision upper. Seems pretty solid no flex to it. I cant say it's not exactly what I ordered up to this point I'm still waiting for BCG and charging handle. Otherwise its seems like good quality.
