Description

Our new and improved billet AR-9 80% lower is here!

Featuring an updated design with better aesthetics, a new magazine catch and ejector fasteners, our second generation AR-9 80% lower is better than ever. Made from quality billet 6061-T6 aluminum. Compatible with standard AR-15 lower parts kit components, and all 9mm AR uppers.

ONLY compatible with standard 9mm GLOCK® OEM magazines.

  • LRBHO (Last Round Bolt Hold Open) – Since our AR-9 lowers do not house an internal linkage for the bolt catch, you’ll need an upper receiver with integrated LRBHO to keep the bolt back on an empty magazine. Double-check your upper’s specs to ensure full functionality.

    Have not finish my build yet.

  3. Chris Pozniak –

    Instructions Would Have Been Nice

    US

    Everything went well in the long run I guess but when it came down to assembling the lower parts kit all I was able to find was a video for standard AR15.It helped some but not exactly the same components so a bit frustrating.Ended up taking longer than it should have.

  4. John Gale –

    good deal

    US

  5. Rod BENNING –

    Nice lowers

    US

    At first glance they look nice out of the box. Just what I expected. I didn’t get a chance to mill them yet. I’ll post more later.

  6. Derek J –

    It’s nice but has a flaw

    US

    I will say the lower looks great shipping was on time. My only issue is and maybe it’s just me complaining. But it comes with a very nice mag catch with a machined area for it. my concerns are the burrs that were left in the area it installs into. I can tell is was from the Cnc machining of the pocket for the mag catch. 30 seconds with a file before it was all coated would’ve made it 5 stars. Now I have to damage the coating in the area to remove the burr before I can assemble it. Still a very nice lower. It’s going to be a shooter not a safe Queen. But the machinist in me is crazy about the over sight.

  7. Jason Canchola –

    Great

    US

    The experience was great it got here fast and every thing was there

  8. Paul Zitterbart –

    AR9 lower

    US

    Received the product very quickly after placing the order, excellent quality. Had one minor problem with the latch pin being oversize. Contacted customer service, who responded immediately and sent a new pin ASAP. Now everything fits perfectly.

  9. Michael Martorana –

    Very Happy with the AR 9 Lower

    US

    its a good blank it has a flaw that the mag release sticks and once you put the mag release pin in there no way of getting it out. rest of the lower every fastener is screw in thats a plus!!

  10. Mack Gross –

    Easy to complete

    US

    Awesome.
