The "2011" of AR-15s

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
