[QUOTE="Turpentine21, post: 2706372, member: 124909"] You use an adjustable gas block to regulate the speed of your bolt carrier. If the carrier starts coming back to early before your fired brass shrinks you can get case head separation. If it’s over gassed the extra bolt speed can also be tough on the gun. An Adjustable block allows you to tune bolt speed. And get your ejection angle correct. You can also tune with buffer weight and spring stiffness. There is likely a large dwell time difference between his gun and yours because of barrel length and gas system length. One may also be over gassed or under gassed due to port size. Even the difference in chamber sizes will make a difference. [/QUOTE]
