Building Out Your TAC-9 Receiver (blog entry for FAQ and build data)
Love all of the TN Arms products!
Had to make a few minor adjustments for the take down pins to fit
So far I've got about 250 rounds through my tac-9 lower with no problems, mags lock in perfect, ejector works flawless, and my trybe 9mm bcg has no problems feeding or ejecting spent round.
Would recommend to anyone looking for a lightweight polymer lower!
Worked great with my PSA upper, would buy again.
I purchased this to build a 9mm pistol to have as a truck gun and I couldn't be happier. Pulled it out of the box and had all the internal parts put in in under 15 minutes. Only problem I ran across was the ejector needed a little bend to one side because the gun would jam after the second or third bullet but that's a quick and easy fix. Highly recommend, would purchase again!
Overall, I'm pleased with this lower. The only issue that I had was with the installation of the trigger group. I used a Hyperfire EDC trigger, and it wouldn't fit without grinding off the front corner of the aluminum block which has the serial number of the receiver on it. When I contacted Tennessee Arms about this, they asked if I was using one of the drop in triggers. I haven't measured the Hyperfire to see if it's wider than milspec, but that may be the issue. Regardless, once I removed a small amount of material from the block, the trigger fit correctly, and has given no problems. If I decide to build another pistol caliber AR, I will probably use a Tennessee Arms lower again.
This company has quality products and great customer service. I would definitely recommend.
I’ve always wanted to build a ar9 when I got
Lower seems well built. Lower parts kit fit well. Tried two different, high quality, uppers and both were extremely difficult to mount. Shooting impressions were the same. I had reliability issues With bothering uppers and all magazines.
