This Mil-Spec buffer tube allows for six different stock positions, providing flexibility for shooter comfort and adaptability during use. You'll commonly find this assembly paired with builds utilizing a carbine gas system in 5.56 NATO caliber rifles, making it a versatile choice for many AR-15 configurations.
