"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 was skeptical about this lower being a polymer, but I am impressed with it. It a little loose on my upper. Definitely going to be careful with it don't think it could handle anything to rough.

    This item is NOT DPMS compatible. I have a 308 upper that won't fit with this lower. Now I have to spend more money. Plz indicate what compatibility your items are with
