CYBER MONDAY SPECIAL — BUY ONE GET ONE FREE AR-9 lowers. Limited time. While supplies last.

AR-9 Builders… it’s your moment.
For a limited time, when you buy one AR-9 lower, you’re getting a second one free. Start one build now and keep the other ready for the next idea, the next range trip, or the next flex in your collection.

Two lowers. One price. Zero excuses not to build.

Mil-spec fit for maximum customization
Our AR-9 lowers keep everything tight and true with full mil-spec compatibility, giving you the freedom to run your favorite parts, uppers, and internals without fitment games.

Why builders pick these lowers

  • Built to take the harshest punishment. Precision machined from aircraft-grade billet aluminum for superior strength and long life.

  • Broached, flared magwell for faster, easier reloads.

  • Heavy-duty integral trigger guard for winter use with gloves.

  • Rear takedown lug pocket completed for smooth assembly.

  • Threaded bolt catch release hole, and threaded rear takedown detent hole for easier lower parts kit installation.

  • Includes Bolt Catch Screw Set, Polymer Lever, and AR9 Hardware Set. (Aluminum levers are offered as an upgrade)


Limited run for Cyber Monday only. This bundle is excluded from other discounts and promotions. Free AR-9 included while supplies last. Add it to your cart before they disappear.

Customers will be charged for the item of higher value, and the lower of equal or lesser value will be provided at no additional cost.


Lifetime warranty against manufacturing defects guarantees impeccable quality.

We manufacture our lowers using US sourced aerospace grade 6061 aluminum which is more resistant to corrosion and is much easier to mill than any other alloy used to make lower receivers. Our 80% lower AR receivers carry a lifetime warranty.
