"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.

    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.

    I ordered this for my 13 year old daughter's .243 build since she is small framed I wanted to save weight where I could and liked the color variety but surprisingly my daughter selected black instead of any other color. Unfortunately because of all the craziness of this year there was a shipping delay but I knew they're would. Tennessee Arms quickly communicated about the delay and April was awesome and let me make changes on the assembly before it shipped. I had zero fitment issues putting it on my Aero .308 upper and my daughter's BCA .243 upper. Definitely going to be looking here for the next build
