Abstract
A barrel assembly for use in a semiautomatic firearm, including a barrel and a takedown lever. A rear portion of the barrel includes a follower lug and a rear lug extending from an underside of the rear portion. A pin of the takedown lever includes a notch with a vertical face configured to contact a vertical face of the follower notch when the firearm is in the locked position. The rear lug is configured to be supported by a portion of a locking block of the firearm prior to firing and during a portion of the recoil period. A fitting pad extending downward from a rear lug of the barrel can be adjusted to provide a customized fit of the barrel to a frame of the firearm. The modifications to the barrel assembly result in increased dwell time and accuracy of the firearm.
