The Quattro-15 is the next evolution in AR-15 design, utilizing the increased capacity from the QMAG-53, 53-round polymer magazine. The flared magazine well supports a quad-stack to double-feed the magazine. A magwell adapter kit allows the use of traditional 30-round magazine and provides backwards compatibility with STANAG pattern magazines. The Quattro-15 Lower includes an Ambidextrous Bolt Catch, Magazine Release, QD Sling Point, and upper receiver tensioning set screw. MIL-SPEC compatibility accomodates parts from across the AR-15 market. Machined from a 7075-T6 Aluminum Forging, and finished with a Type III Hard Coat Anodizing

Introducing the Loadout Kit - your all-in-one solution for firepower and versatility. This kit includes 4 QMAG-53 magazines and the Quattro-15 Magwell Adapter, combining to provide you with a complete loadout of 212 rounds in a single package.

QMAG-53

The QMAG-53 is a 53 round magazine and is compatible with the Quattro-15 lower receiver. The Quattro-15's 53 round magazines give patriots the ability to carry a 210 round loadout with only 4 magazines instead of 7. That's 50% less reloads and an 8% lighter loadout weight. The QMAG-53 is a single spring, single follower design which allows for unrivaled reliability, especially during suppressed fire.
