Tennessee Arms Company is proud to offer our AR-308 complete lower receiver. All colors are molded directly into and throughout the entire receiver so you never have to worry about wearing it off unlike a painted finish.

The AR-308 series does not have a specific set of industry standard dimensions like the AR15 has. We recommend the Bear Creek Arsenal, Aero Precision, Head Down Products, JSE Surplus, and the PSA Gen II series for the best fit.

TAC Patent Pending design is Reinforced Nylon 6-6 with Marine Grade Brass threaded inserts molded into the material for strength and corrosion resistance.Our receivers are designed to accept any quality lower build kit. Using the Metal inserts into a high impact polymer receiver make the Tennessee Arms Receiver truly the Highest Strength/ Lightest weight hybrid receiver (6.2oz) on the market. We ARE the best receiver on the market and always will be.

"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 Expert from a Third Party Review

This is my second complete lower in .308. I was super impressed the first time and even more so the second. Thank you for being artists in your profession!

This is a great lower as I have shot around a thousand rounds through it already without one jam.

Great lower so far!!
Posted by Ethan Schrick on 23rd Mar 2022

This has been a great lower so far. I’ve put 100 rounds or so through it and it has held up. I love how light weight it is and look forward to buying another one for a new build here soon.

Blog Post About Product

Washington and Illinois AR15 Bans

Washington and Illinois have both recently passed laws banning the sale and distribution of assault-style weapons, high capacity-magazines, and switches that convert handguns into assault-style firearms. Both laws were met with strong opposition from gun rights groups, and in response, both states have faced lawsuits.
