"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.

    Wonderful fit and finish, better than expected. Is very light and looks great with the camo laxer engraving.

    Mates perfectly with my aero upper. Solid and tight and can’t beat the price.

    Recived the lower. Still waiting on my upper from another source but the lower seems to be very solid and the workmanship is superior! cant wait to complete this build. Only negative is I ordered FDE and got black... no worries thought as I don't really care :)

    Buffer tube wasn’t screwed on enough. The pin the holds buffer and spring in tube came out first couple rounds. Just turned buffer tube one full turn and everything is fine. It was barely holding pin before I did that.

    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.
