"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.

    This is a great lower as I have shot around a thousand rounds through it already without one jam.

    I was a little skeptical at first! But after purchasing the AR 10 complete lower I was truly amazed. Very sturdy built and looks great! Thank you Tn Arms for such a great affordable product.

    Great lower so far!!

    Posted by Ethan Schrick on 23rd Mar 2022

    This has been a great lower so far. I’ve put 100 rounds or so through it and it has held up. I love how light weight it is and look forward to buying another one for a new build here soon.

    I now have 3. 1 on a 308 and 2 other .243’s. Love them. I have one .243 down to 6.3 lbs with 16 in Wilson Combat ss barrel. Functions great. Shipping/customer service is on point as well.
