The Mustang Armament Chesty 11.5" 5.56 NATO pistol brings duty-grade performance and suppressor-optimized reliability to a compact AR platform available at Battlehawk Armory. Named for Lieutenant General Lewis B. “Chesty” Puller, this custom billet build is engineered without compromise, combining a premium billet receiver set, proprietary barrel system, and enhanced operating components into a cohesive fighting pistol ready for hard use. Every element is selected and tuned for consistent cycling, reduced gas blowback, and precise control whether suppressed or running open.

At the heart of the Chesty is an 11.5-inch barrel system paired with suppressor-optimized gas dynamics, an advanced recoil system, and fully ambidextrous premium controls. The platform ships configured with a Sig Sauer Romeo8T-AMR red dot and 3x magnifier, Holosun RAID weapon light, and SMS Trinity Visible/IR laser with IR illuminator, plus two 30-round magazines. The result is a turnkey, night-capable defensive and duty platform that delivers rapid target acquisition, positive identification, and reliable function under pressure.
