    PRI Fat Boy Replacement Gas Tube for M4 Carbine

    The PRI Fat Boy replacement gas tube for M4 Carbine is a replacement gas tube for M16/M4 rifles that uses a 9.8” long tube. One important benefit of using the Fat Boy gas tube is that it minimizes the weapon’s cycle time to 700/850 rounds per minute. It was made for use with the known buffer system and replaces the standard gas tube with no changes to the firearm. The Fat Boy gas replacement tube is perfect for barrels with length of 12” and 14”. Failing to hold open on the last shot is one of the common signs of over buffering a weapon.
