4 Pack- TNARMS 15

You Pick The Colors!!! 

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 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.


Excerpt from Guns and Ammo Book of the AR-15 #5 2014

 "TAC has effectively reduced weight and boosted aesthetics while maintaining functionality and durability"

 Excerpt from a Third Party Review at

  "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

    Great lower, fit is great. I have purchased 5 lower for builds and have no issues with quality of the product. Great for budget priced lowers for home use. I will be purchasing more of these items.
