The Ronin Competition Left-Handed 16.5-inch Mid-Gas 1:7 5.56 NATO AR-15 Complete Upper is engineered for precision shooting and versatility. Featuring a 16.5-inch "Satellite" barrel made from 4150 Chrome Moly Vanadium with a QPQ Nitride finish, it provides enhanced durability and accuracy. The barrel's 1:7 twist rate is optimal for stabilizing a wide variety of 5.56 NATO ammunition.

The freefloat 15-inch M-Lok handguard, crafted from 6061-T6 aluminum, allows for secure accessory mounting while minimizing weight. The left-handed dedicated upper receiver is a Black Diamond Series slick slide design, anodized for improved wear resistance. This complete upper also comes with a premium left-handed bolt carrier group and is threaded for standard AR-15 muzzle devices. This build is ideal for left-handed gunsmiths seeking functionality and performance in a streamlined configuration.
