Welcome to TPM ARMS, LLC


TPM Arms specializes in developing and producing precision parts and components for the firearm enthusiast.  We are extremely proud to say our products are AMERICAN MADE.  Our lower receivers are forged using the highest quality materials available and held to tight tolerances.

We take great pride in our manufacturing processes and quality products.  If for any reason you are dissatisfied with your purchase we'll do everything in our power to correct it.  If you find our product is defective, we’ll replace it. No questions asked, just return it (in like new condition) for replacement.  It’s as simple as that. 

  • All lower receivers are manufactured using 7075-T6 Aluminum.  We do not take shortcuts in manufacturing and cost cutting by using 6061-T6 Aluminum which is not nearly as strong as 7075-T6 Aluminum.


Material Statistics:             Tensile Strength                 Brinell Hardness

7075-T6 Aluminum                      83,000 lbs                                 150

6061-T6 Aluminum                      45,000 lbs                                  95

As you can see the numbers speak for themselves.  These two materials are considerably different in strength and hardness due to their different chemical analysis.

We strongly recommend that no matter where you purchase your Lower Receiver(s) that you always insist on 7075-T6 Aluminum which is the material required for mil-spec lowers.  Forged or Billet, insist on the best and safest materials.  There is a very good reason why  the US Military insists on this; the safety of our troops and the reliability of their weapons.  Don’t you deserve  the same?

We invite you to browse through our store and shop with confidence. We invite you to create an account with us if you like, or shop as a guest.  Either way, your shopping cart will be active until you leave the store.

Thank you for visiting.
