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.

    Another great lower

    Posted by CAYLAN ALLMAN on 5th Mar 2018

    I purchased a pink lower to make a build for my wife. She was very happy with color and how it matched up with her Pink ERGO grip. Went together well with zero issues.

    Perfect Fit

    Posted by Trey on 5th Dec 2017

    Fast delivery to FFL and couldn’t be any more pleased. Color was consistent throughout and matched Magpul OD green perfectly. Really tight tolerances with parts kit (DMPS kit) and once the upper was attached (Hardened Arms) it was a really tight fit. Out of the box the lower had no burrs and was completley smooth. I had to do no alterations or shaving of the lower to make parts fit. I will definetly be a return customer. Great product and I love supporting local businesses.

    Best polymer lowers on the market

    Posted by Samuel Groom on 31st Dec 2016

    All of my lowers from on out will be tnarmsco hybrid polymer lowers. I've had multiple polymer lowers from other companies that I've put through stress tests and they have almost all broken. Tnarmsco lower sustained more stress than some billet and forged aluminum lowers. These lowers are phenomenal. Finally someone has gotten it right! Do not have doubts when purchasing these lowers. They are all well manufactured and require little to no work to assemble for use with the upper of your choice. Bravo tnarmsco. Bravo.

    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

    Posted by Ken G on 22nd Nov 2016

    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.
