Tennessee Arms Company is proud to bring to the market our newly designed TAC-9 style lower receiver.

The TAC-9 receiver is the newest member of the Tennessee Arms family of receiver. Using our fiber reinforced polymer and metal inserts we have delivered the lightest and best designed Glock Magazine compatible lower receiver on the market today. This receiver comes with our proprietary ambidextrous magazine release already installed. The rest of the lower receiver parts are standard AR design.  These parts are in stock and ready to ship. 

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. The ejector is permanently embedded in the material. 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.

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.  

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.

    Great Lower!

    Posted by Jason Clark on 18th Dec 2019

    Great Lower! All the pieces of my lower parts kit fit perfectly (better than my last build with aluminum lower), Glock mag fit great. I had to file down the ejector arm a little per the instructions, but I have already ran about 50 rounds through my AR-9 without issue. I'd totally buy another one especially considering the price difference between this one and all the other dedicated AR9 lowers.

    Very tight very nice

    This lower is very tight on some standard Aero precision uppers I have, has a ambi magazine release which I like, wouldn’t accept a strike industries anti walk pin set but this lower is very tight and should work great once it’s broken in.

    Only time will tell but so far this lower has functioned exactly as I hoped. Putting it together was just as easy as using an aluminum lower. Fit and function has been good so far. Plan on attempting a 308 very soon.

    The lower seems to be very durable, however the extractor was too tall by about 3mm (this could have been tolerance stacking however) on top of this though, there was too much material at the forward end of the threads for the buffer tube resulting in the lower rubbing on the bolt carrier. I was able to fix my issues with a dremmel.
    However this lower took about 3.5 weeks to ship to me.

    Takes Some Work

    Posted by DMTX1010 on 13th Sep 2019

    This receiver looks great and is really light. I installed an Unbranded AR ELG LPK and Strike Industries Anti Walk/Rotation pins with no issues. I used a buffer tube with the anti tilt retaining ears as suggested. I do not believe a tube without the retaining ears would have worked at all for my build due to the placement of the buffer retainer hole. I finished out the build with a Zaviar Complete Upper from 22Mods4All. This upper required major adjustments at the pin holes and buffer tower. It took me a couple hours sanding and filing little by little to get a fit that was just right. Things are still a little tight, but it will break in and loosen up with time. I chose an FM9 BCG for the build which also required major fitment. The ejector was sitting much too high and required much more to be filed away than was implied in the TNArms instructions post. After filing the ejector and checking clearance repeatedly, I finally got to an acceptable clearance. Test firing the rifle went great overall. The receiver held up well and functioned as expected. My final feedback is on magwell clearance. The magwell allows enough slop on Glock mags that if the gun is not held completely flat then the mags cant left or right just enough to cause the bcg to smack the back of the mag. Both of my metal lined Glock mags got damaged and required filing to repair. I did find that Magpul GL9 mags fit much tighter in the magwell, which reduces the slop and prevents the mags from canting far enough to be damaged by the BCG. I will be using Magpul mags exclusively in this lower going forward.

    Overall the receiver works well and is very functional for the price. If you pick this up then be prepared to put in the time and patience needed to make it a perfect fit. Regardless of the issues I had, this lower is still a very solid option for a lightweight and/or budget build.
