    I have a similar build with a Tennessee arms lower the tac-9 and a 3" fm9 upper but I am having I guess ejection issues or possibly feeding issues anything u could help with as I see urs runs good.

    Good Video! I really hope these lowers have changed, I bought 5 of them all finished 556 lowers from Tennessee Arms and they were all out of spec and garbage, plastic flashing left all over, trigger pockets so warped fire control groups would not fit in, and the ones that were not warped, warped after first couple outings, rear tower out of spec and cockeyed so carrier would stick in the crooked buffer tube, mag catch slot out of spec and causing mags to sit to low, hammer pins turned oval on 2 of them within 300rds and on and on, they were all a nightmare, out of the 5 i bought only 1 is even currently on a functional firearm and works but it has a out of spec tower and warped trigger pocket, one of them i got so mad one day i just dropped it from about 3 ft onto the dirt range, and it shattered like a piece of glass. I am a fan of poly lowers, I really like the ATI omni gen 2 hybrids, also had good luck with ep armory and new frontier, I tried everything to make these lowers work and there was just so many issues for each lower it was just a losing battle. The customer service was horrible, I called twice and both times got treated like their lowers are perfect and never have issues and it must be something i did or the parts i used were out of spec. These lowers were so bad I cant believe they passed QC, I have no idea how to trust this company ever again with my money. With the price of a endo mag conversion which work well, or a magwell adapter which even the promag works great, its hard to beat a regular $30 anderson lower for a 9mm build

    That’s a sweet ar9 for sure… I just finished my build also using a TN Arms lower… No issues with it as of yet… She shoots smooth… I’m liking it a lot… Quick question for ya… I’ve noticed that everyone seems to mount their backup sights differently… I just got a set Tacticon flip-up irons in, but can’t make up my mind which way they should be facing… I tried to find a video out there on it, but the ones I did find didn’t actually show how to install em… Any recommendations…? This might be a video you could make…! Thanks…!

    Watching this for probably the 5th time I just remembered another YouTuber had issues with the KCI glock mags that he ended up addressing with Wolf springs. Kinda like putting lipstick on a pig but…

  5. Matt Fleming on February 24, 2023 at 2:24 am

    Could you put a 26 mag in there?

  6. Justin Credible on February 24, 2023 at 2:24 am

    Very pretty gun. You can always change the lower to something better. Last round hold open not huge deal though. Ak47 and mp5 don’t have them and they’re very popular

    Hey bud I noticed you shooting at targets where you may not be able to see where your bullet flys. Probably your property but it’s always good to know what’s beyond your target. This is something that was instilled in me at a very young age. 1:15 and I feel likes it’s every gun owner, sportsman and hunters responsibility.

  8. Alex Hueramo on February 24, 2023 at 2:25 am

    Very nice looking gun. I’m crossing my fingers they have since corrected these issues. I just ordered a Tac-9, 308, and AR 15 lower from them. I bought them because of their affordability. So it would seem you get what you pay for? Thanks for the information.

    I love mine. Only issues I had was I had to grind the ejector flat and I wish the magwell didn’t have so much play/wiggle room. And being a AR9 I have feed issues but that’s another story.

    The springs on those korean mags are thrash, just change the springs for wolf springs or +10% power springs and they will work fine

  11. Brandon Turner on February 24, 2023 at 2:35 am

    Where did you order your upper receiver and parts kit from?

  12. Derrick White on February 24, 2023 at 2:39 am

    What size buffer are you using?

  13. Warthog 71 on February 24, 2023 at 2:39 am

    It’s still running well, minus the Kormags. Looks great too!

  14. ROBERT LAMETTE on February 24, 2023 at 2:40 am

    Is there a drum Compatible with these tac9 lower??

  15. Isaac Gomez on February 24, 2023 at 2:42 am

    Did you have any figment issues with your lower and upper?

  16. Zeph318 on February 24, 2023 at 2:50 am

    Can you make a video on how to ensure the tac 9 will run reliably and a build breakdown

  17. DILLIGAF on February 24, 2023 at 2:54 am

    I have one of these lowers and I’m not impressed. I hope yours works out for you. Me personally I’ll be getting another lower as soon as I can

    I don’t believe anything likes Korean Mags. To me, Glock & Magpul mags are cheap enough that I don’t bother with anything else. The ETS’s have been mostly ok. Even though I have the awesome American Resistance Gear lowers. I might build a lower like that. For $30 bucks, I’m in 👍🇺🇸

    *tennessee arms seems to have exit scammed i have $150 on order since april 2021 and they are no longer responding to emails*

    Problem with the Korean mags is interesting. Reverse engineering isn’t that hard. I’ve seen them with polymer overmolding before though. All my mags I disassemble, clean, squirt some silicone, and give a yank on the spring before I use them. My thinking is that is basic maintenance and if there are any loading problems at least I can rule out Korean cigarette ash as the reason it didn’t feed.

    So my Tennessee Arms AR9 lower is to tight on the magazines and I’ve tried 3 different brands. Any one else have that issue? How did you fix it?

  22. Radom Guy on February 24, 2023 at 3:09 am

    I bought a lower from them and it was perfect. So I decided to buy another one, this time an 80. I had the same problem with the wall of the detent for the rear takedown pin. in addition,, the rear takedown pin holes were off spec. It’s ridiculously difficult to get the pin in with its upper (I tried other uppers and lowers and the problem is definitely with the Tennessee lower). I bought a takedown pin set that comes with a detent that is about twice as long as a standard detent so it can utilize the meat of the wall behind the area where it broke through. I had tried a KNS push button takedown pin that does not require a detent at all. The problem was that because the takedown pin holes are not within spec, it’s very tight going out. That makes its push button difficult or impossible to operate.

    I contacted Tennessee Arms twice: once sending an email to two of their contacts (the owner and April). No response. I then sent it via their web form. Still no response.

    At this point I did not call because we are in the middle of the whole ATF receiver rule so I am currently giving Tennessee a pass, as the gun is functioning, just not as smoothly as it should be. Call me a sucker but despite this, I ordered a blem TAC9 80 on clearance before the ATF deadline went in effect. Hopefully I won’t have problems with it but it could go either way.

    I know that you said it took about two months for them to get the lower back to you. How was the warranty experience overall?
