"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.

    AR-308 Lower

    Posted by Joe on 2nd May 2018

    I just received my lower receiver. I am please how well built it is. My .308 upper hasn't been delivered yet so I can't comment how it worked on the range, but I have high hopes.

    Good price, excellent product and customer service

    I received my 308 complete lower a few days ago and I could not have been happier with the result. It took a little longer than expected to receive it, but it was well worth the wait. Very light and it seems really strong.
    Customer service has been excellent throughout too.
    I'll definitely be ordering more for subsequent builds.
