Utilizing a gas-piston operating system, the Stag model 8TL will run cooler, cleaner, and more reliably than a standard AR-15. Featuring a 16", 4140 steel, chrome lined government profile barrel, this rifle will take anything you can throw at it. The free floating Diamondhead rail improves accuracy, and provides an unlimited number of combinations with removable rail sections (not included). The flat-top upper comes pre-mounted with Diamondhead flip up sights, and the six-position stock is adjustable to fit shooters of all shapes and sizes. Includes one thirty round magazine.
