    *As this barrel is likely to be used in full-auto applications, we are opting to stick with a 5.56 chambering to ensure absolute safety for our customers. 

    **Due to the short dwell of the barrel, the gas port will be larger than most barrels. Customers are encouraged to use an adjustable gas block for optimum functionality.
