The Stag Arms Stag 15L Left Hand Tactical Nitride Upper is a complete AR-15 upper receiver assembly built around a 16 inch 5.56 NATO barrel. Designed specifically for left-handed shooters, it combines a durable anodized finish with a nitride-treated barrel and a slim, extended handguard that offers generous mounting space while keeping weight balanced and manageable.

This 5.56 mm NATO upper uses a 1/2-28 threaded muzzle and a 1:7 twist rate to stabilize a wide range of bullet weights, making it a versatile choice for training days, range work, or general-purpose use. The medium contour barrel and full-length rail provide a solid foundation for optics and accessories, while the left-hand configuration helps deliver a more natural shooting experience for southpaw shooters. Stag Arms is known for purpose-built AR platforms that emphasize reliability, thoughtful ergonomics, and consistent performance.
