This must be sent to an FFL dealer, this IS a firearm


Tennessee Arms Company is proud to bring to the market our light-weight, incredibly strong, AR-15 style lower receiver.

Manufactured from a fiber-reinforced Nylon blend with extreme resiliency. Using our patent-pending technology, Marine-Grade Brass inserts are permanently molded into the receivers at the Grip Screw & Buffer Area. These metal threaded inserts increase durability without sacrificing weight savings of the composite bodies. Colors are injected throughout the receiver during molding thus eliminating the worry for a scratched or marred finish.The end result is a sturdy receiver that is light to carry without compromising functionality.

Sporting a redesigned bolt catch area, a repositioned buffer retainer, and all the upgrades from previous models, this design is optimal. Enhancements are from customer-expressed opinions that we valued & then turned back into our product. Our receivers are constructed to accept any quality mil-spec Lower Parts Kit. With an unmatched versatility for parts, customers are pleased when the builds are completed. Tennessee Arms Company is unceasing in our efforts to improve our design for our customers' future builds.


Our AR-15 has the ability to be modified to fit Fixed-Stock Tubes (A2). If you are aware that you will be using this type, please let us know and we will modify the lower for you before shipment. If you are in possession of your lower, and do not wish to send it back, it can be modified at home. .0625" (16th) needs to be taken off the back for the tube to engage the retainer. (We recommend a belt-sander). 


ALL TN ARMS CO Products come with a lifetime guarantee. We stand behind our products 100%. We believe the finest way to show this is through impeccable customer service which includes a warranty that stands firm. We invented the hybrid lower receiver, and we work continuously to keep it second-to-none. 

  • Nylon 6-6 Body
  • Marine Grade Brass inserts in Buffer Tower and Pistol Grip
  • Lifetime Warranty against Breakage or Failure
  • Available in Magpul Matching Colors
  • 5.6 Ounces Stripped


Federal law requires that you be 21 years or age or older to purchase a stripped receiver or frame. Even 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.

Upon ordering, please list the contact information for your desired FFL.

    light weight

    Posted by Unknown on 29th Nov 2016

    First impressions when I pick this up. It is very lightweight, and very strong and very stout construction. Everything that has threads has brass reinforcements which is a nice touch, I have not seen this on any other polymer lowers.
    My only reservation of this product is that the quality of the finish isn't super great. There are a lot of rough edges and the finish is not as smooth as I expected. That being said, it's nothing you can't fix with a half hour of trimming.

    Great stuff

    These receivers fit and work great. The warranty is great peace of mind for SBR builds, and their customer service is great. I've been a gunsmith for almost 25 years, and right now all of my personal AR rifles are built on these lowers.

    A Must have!

    Posted by Adam on 22nd Oct 2016

    Fit & finish is great! All parts went on perfectly and no clean up was required for fitting. If you're finicky a small file works well to clean the corners. The upper fits tightly with no need for an accus wedge. Color matches Magpul very well! If you are interested in the polymer lowers this is a must have! Feels quite solid. It takes a good amount of force to flex it. Not wimpy at all!

    mixed feels

    Posted by Justin on 2nd Jul 2016

    Let me start by saying the lower functions fine and I understood there would be some diy involved before buying.

    The lower does need some sanding here and there to fit, totally fine. My biggest problems were the pistol grip fitment and the sides that cover the trigger assembly are bowed in sightly.

    Once installed, the milspec grip sticks out about 1/4 of an inch where the webbing of your hand would be. The same grip is flush on a normal receiver.

    The bowing of the sides make the safety switch stick out from the receiver. Probably gonna make it hard to trade or sell someday.

    Still functions great and I can deal with these issues. Awesome service and fast shipping to ffl.

    next gen guns are here!!!!

    Posted by scott on 1st Jul 2016

    When I got the box I thought it was empty, that's how light this lower is. After leaving the gun shop I threw my lower on the ground and ran it over with my Fullsized F 150 and expected it to shatter low and behold it retained shape and mags drop freely. Best lower for the price and color is close to the magpul od green. A shade lighter.
