USED Stag Arms STAG-15 Model 3L Left-Hand 5.56 NATO 16" – Diamondhead Rail & Flip Sights

The Stag Arms STAG-15 Model 3L is a factory left-handed 5.56 NATO carbine built specifically for shooters who prefer the controls and ejection pattern reversed from a conventional AR-style setup. Stag was one of the early manufacturers to offer a genuinely left-hand upper rather than simply adding ambidextrous controls, making models like the 3L especially appealing to left-handed shooters. Factory documentation confirms the Model 3L used a left-hand forged upper receiver and was chambered in 5.56 NATO. 

This example has a 16-inch barrel marked 5.56 NATO with a 1:9 twist and is fitted with a Diamondhead free-float style handguard, Diamondhead flip-up sights, vertical foregrip, adjustable carbine stock, and a rail-mounted light. The left-side ejection port and mirrored bolt arrangement are clearly visible in the photos. A flash hider and full-length top rail round out the setup.

The overall condition appears very good, showing normal handling and use marks but no obvious major damage. It comes with the pictured hard case, magazine, cable lock, paperwork, vertical grip, flip sights, and mounted light. The exact manufacturer/model of the light is not clear enough from the photos to identify confidently.
