The Tennessee Arms Company, hybrid receiver specialists, is taking pre-orders for their highly-anticipated pistol-caliber AR lowers. Their new AR-15 lowers are lightweight, affordable and compatible with Glock-pattern magazines.
Called the TAC-9s, these are “small frame” receivers built for 9mm Luger, .357 SIG and .40 S&W components. They have snug but drop-free magwells with ambidextrous magazine release buttons for left- and right-handed use.
The Tennessee Arms Company has been developing the TAC-9 for more than two years. The company has been wildly successful in the lightweight receiver business, proving that the technology and materials are there as alloy alternatives.
The company is taking pre-orders for stripped receivers (magazine release components are included) for $89, with custom engraving optional for an additional $10. They are also taking orders on complete lowers with MIL-SPEC M4 Carbine parts for $189.
Delivery is expected in the next six to eight weeks. Existing customers will enjoy an additional ten percent off with the discount code “PRIORCUSTOMER” (without quotes).
Like their other lowers, these new receivers are hybrid glass-filled nylon lowers with brass inserts for improved strength and reliability. Additionally, these receivers are heavily reinforced and overbuilt for use with direct blowback uppers.
The buffer extension and pistol grip are molded around threaded brass reinforcements. Not only do these add strength at key locations, they also allow users to install and remove pistol grips and buffer tubes without having to worry about stripping the threads out of the receiver.
Because the bulk of the receivers are polymer, they offer some improved function over conventional cast or milled lowers. The polymer is flexible and can bounce back from hits that would permanently damage an alloy part. And the finish is embedded throughout the material, making these lowers somewhat scratch-proof.
Direct blowback uppers can be hard on lower receivers since they put a lot of stress on the buffer extension. The flexibility of these lowers works to their advantage. With full-auto testing complete, Tennessee Arms is ready to kick off mass production and take orders now.
The reduced weight helps offset the added bulk of pistol-caliber AR uppers, which should give these better balance than conventional assemblies.
Tennessee Arms’ lowers are available in a wide range of colors. The receivers are color-matched to Magpul parts. Because they’re a cast hybrid design, they can sell them for considerably less than the bulk of Glock-mag-compatible AR lowers, too.
Everything else is oversized and overbuilt. The magazine well is flared and the receiver sports an integral trigger guard. Despite the added structure the receiver only weighs 7 ounces, stripped.
For anyone still concerned about hybrid receivers today, these lowers come with a lifetime guarantee. If you have any problems with them, the Tennessee Arms Company will be there to help.
